Subject: [PATCH 01/16] Add scripts/get_home_key.py to fetch home keys from the
 HD cloud account (#30)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* Add scripts/get_home_key.py to fetch home keys from the HD cloud account

A fourth way to obtain the HOME_KEY: signs in to the PowerView account
API, exchanges the pvkey for a Firebase token, and reads the same
Firestore home document the Android app reads from. Works for any home
on the account whether or not a Gen3 gateway is reachable, and avoids
the SQLite-extraction route described in the HA forum thread.

The flow mirrors the Android app's (decompiled from
com.hunterdouglas.powerview 3.8.1):

  1. POST /api/v5/users/rcUserSignIn        -> pvkey
  2. GET  /api/v5/homes                     -> documentId per home
  3. GET  /api/v5/firebaseAuth/userToken    -> Firebase custom token
  4. Identity Toolkit signInWithCustomToken -> Firebase idToken
  5. Firestore homes/{documentId}           -> home.key

Empty and the sentinel '00112233445566778899AABBCCDDEEFF' are reported
as 'not set', matching the app's CloudDecoder behaviour.

README updated to list the new method alongside the existing three.

* Send the same identity fields the Android app does

The previous body fields (`deviceAppBrand: "PowerView"`, `deviceAppId:
"python-client"`, `deviceName: "python"`, etc.) and the default `requests`
User-Agent would stand out trivially on the Hunter Douglas server side.

Match what com.hunterdouglas.powerview 3.8.1 actually sends:
  - deviceAppBrand "HD"  (BrandConfig.getAppBrandName for the 'hd' flavor)
  - deviceAppId "<16 hex chars>hdrelease"  (BrandConfig.appDeviceId; 16 hex
    chars derived from sha256(email) for stability across runs)
  - deviceName / deviceType "Google Pixel 8"  (Build.MANUFACTURER+MODEL)
  - language/region from a fixed en_US locale
  - User-Agent "PowerView/3.8.1 7911 (Google Pixel 8 en_US)" on every
    Hunter Douglas request  (PowerViewApplication.getUserAgentString)

The User-Agent is now applied via a `requests.Session` shared by all three
HD endpoints. Firebase/Firestore calls keep the default User-Agent — those
endpoints aren't HD-controlled and the app uses the Firebase SDK there
anyway.

 1. Via adopting a BLE shade: There is a [shade emulator](/emu/PV_BLE_cover) that works with Arduino IDE and an ESP32 device (&ge; 2MiB flash, &ge; 128KiB required), e.g. [Adafruit QT Py ESP32-S3](https://www.adafruit.com/product/5426). Install and connect via serial port, then go to the PowerView app and add the shade `myPVcover` to your home. You will see a log message `set shade key: \xx\xx\xx\xx\xx\xx\xx\xx\xx\xx\xx\xx\xx\xx\xx\xx` . Copy this key. You can delete the shade from the app when done.

Subject: [PATCH 02/16] Fix device merge, data wipe, staleness; add
 gateway-driven home key extraction

Bug fixes
- Device-registry merge from non-unique identifier: coordinator.device_info
  used (DOMAIN, self.name) where self.name is the BLE-advertised local
  name. When firmware fallback or transient mis-advertisement made
  multiple shades share a name (e.g. "AWEI T13 Pro"), HAs registry
  merged them into one device record and lost per-shade name_by_user and
  area assignment. Switched to (DOMAIN, format_mac(self.address)).
- Position wiped on every BLE event: self.data was reset to just
  {ATTR_RSSI: rssi} on every event, then conditionally merged with
  manufacturer data. Any non-V2 packet (or empty decode) left the cover
  with no position, surfacing state="open" with current_position=None
  even on closed shades. Now preserves last-known V2 fields and only
  updates them when a V2 advert decodes successfully; state-of-the-moment
  flags (is_opening/is_closing/battery_charging/etc.) are still cleared
  per-event so movement bits do not latch.
- home_id stickiness disabling controls: cover.supported_features
  returns 0 when home_id != 0 and HOME_KEY isn't 16 bytes. With the
  data-preservation fix above, this gate now correctly triggers, but
  many paired roller shades accept plaintext commands even without
  HOME_KEY, so the gate is over-protective. home_id is now consumed
  (drives api.encrypted) and popped from self.data so UI controls stay
  visible; cipher is applied only when both home_id and a real 16-byte
  HOME_KEY are present.
- Stale entities masquerading as fresh: PassiveBluetoothCoordinatorEntity
  treats any BLE address activity as "present", so an out-of-range
  shade kept reporting its last known position indefinitely. Added a
  data_available property on the coordinator (True iff V2 advert decoded
  within STALE_AFTER=300s) and overrode available in cover/sensor/
  binary_sensor to AND with it. RSSI sensor is exempt.

Gateway-driven home key extraction
- New gateway.py: async aiohttp port of scripts/extract_gateway3_homekey.py.
  Probes a PowerView Gen3 gateway over HTTP, walks the shade list, and
  asks each in turn for its home key via the GetShadeKey frame. Any
  single successful response is sufficient since all shades in one home
  share the same key.
- New key_store.py: thin wrapper over homeassistant.helpers.storage.Store
  that persists the 16-byte key as hex in
  .storage/hunterdouglas_powerview_ble. Outside the integration source
  tree, so HACS updates cannot wipe it.
- Config flow now offers a top-level menu: "Extract home key from a
  PowerView gateway" (one-shot helper that aborts without creating an
  entry) or "Pair a PowerView shade" (existing BLE pairing flow).
  Zeroconf discovery via _PowerView-G3._tcp. auto-triggers the
  extraction flow when a gateway appears on the network; skipped once a
  key is already stored to avoid Discovered-tile spam.
- Coordinator now accepts home_key as a parameter (resolved from the
  store at setup) rather than importing const.HOME_KEY directly.
  const.HOME_KEY remains as a final fallback (default b"").

manifest bumped to 0.24; integration_type changed from "device" to "hub"
to reflect the home-key extraction role.

Tested against a 10-shade installation with 4 KDT curtain motors (which
require encrypted commands) and 6 ACR rollers (which do not). All ten
respond to open/close after extraction; previously the KDT motors
silently timed out and const.py had to be hand-edited every HACS update.

+"""Config flow for Hunter Douglas PowerView (BLE).
+
+Two flavours of flow:
+
+1. **Shade pairing** — Bluetooth discovery or manual pick. Creates a config
+   entry per shade. (Existing behaviour.)
+
+2. **Home-key extraction** — a one-shot helper. The user picks a PowerView
+   gateway (via mDNS auto-discovery, or by typing its address). The flow
+   talks to that gateway over HTTP, pulls the AES home key, persists it in
+   `.storage/hunterdouglas_powerview_ble`, and then aborts without creating
+   any entry. The gateway itself is never represented in HA — it's only
+   needed during this single key-extraction call, and after that all shade
+   traffic goes over BLE proxies. HACS updates can't wipe the key because
+   `.storage/` lives outside the integration source tree.

Subject: [PATCH 03/16] cover: stop falling back to _target_position in
 is_opening/is_closing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The fallback was meant to give responsive UI during the brief window
between sending a BLE command and the first advert echoing the new
movement bits, but it has a much worse failure mode: _target_position
is never reset on successful command completion, and api.is_connected
flickers as BLE connections come and go after each command. The
combined result is that hours after a successful set_cover_position,
the entity still reports is_opening or is_closing based on a stale
target — which freezes the cached state on the optimistic write
("state=closed" with "current_position=100" for the rest of the
session) because subsequent state recomputations keep returning a
movement state instead of resolving to the actual position.

Both properties now use only the V2 advert movement bit. State during
a command transitions purely on advert evidence, which is what the
shade itself reports anyway. Verified end-to-end with HomeKit driving
sequential set_cover_position calls across 6 shades: every entity
settled cleanly to state matching its current_position, no stale
movement state lingered after the motors stopped.

Subject: [PATCH 04/16] Expose the "service required" status bit as a
 diagnostic binary sensor

Bit 0x04 of manufacturer-data byte 8 is set on shades that accept
encrypted BLE commands with error_code=0 but refuse to physically
move. Verified against a live installation: of 10 shades, the 2 that
silently failed every set_position call had this bit set, the 8 that
moved correctly had it clear. The bit clears once the motor has been
re-calibrated via the PowerView app or driven through its full range
with the physical remote.

Without this sensor the failure mode is invisible: HA service calls
return HTTP 200, the integration logs no error (the shade ACKs with
error_code=0), and the cover entity just sits at its last reported
position. Surfacing the flag as a binary_sensor with
device_class=problem lets users notice the broken motor immediately
and points them at the fix.

Diagnostic-category sensor so it doesn't clutter the dashboard for
healthy installations.

Subject: [PATCH 05/16] api: correct service_required bit semantics
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Observed live: the bit transiently clears for ~10s when the motor is
actively tracking position (during a remote-triggered move), then
snaps back on as soon as the motor settles. So it indicates "motor
in low-power state", not "permanent calibration fault". The functional
implication for HA users is the same — BLE SET_POSITION commands sent
while the bit is on are ACK'd with error_code=0 but ignored — but the
docstring now reflects what we actually saw rather than guessing.

Subject: [PATCH 06/16] api/cover: send SET_POSITION twice when the motor is in
 low-power state
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Empirically: shades whose advert reports bit 0x04 of byte 8 set (the
service_required flag) ACK SET_POSITION with error_code=0 but ignore it
physically. The pattern can be cleared by sending the same frame again
~500ms later in the same BLE session — the first frame wakes the motor
without moving anything; the second frame, sent while it is briefly
awake, actually drives the curtain.

This is what a physical remote effectively does: button press → motor
wakes → command processed. Without this, HA users have to physically
press the remote or recalibrate via the PowerView app every time a
shade slips into low-power state, even though the motor is otherwise
healthy (battery 100, BLE reachable, encryption key correct).

Implementation:

- api.set_position / api.open / api.close: new wake_first kwarg. When
  true, the SET_POSITION frame is sent twice with a 0.5s gap, both over
  the same BLE connection (disconnect=False on the first send). The
  wake-up send swallows BleakError / TimeoutError so the real send still
  runs even if the wake-up itself failed.

- cover.py: each command path checks self._coord.data["service_required"]
  via a new _needs_wake property and passes wake_first=True when set.
  Shades that don't have the bit set continue to get a single send with
  no added latency.

Verified against a curtain motor (KDT:D079) that had refused every
single HA-issued open/close for hours, reporting service_required=on
the entire time. After this change a single HK press transitioned the
shade from closed/0 to closing/47 within seconds and to open/100 in
~30s, with the bit clearing partway through the move as expected.

Subject: [PATCH 07/16] =?UTF-8?q?rename=20service=5Frequired=20=E2=86=92?=

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

"Service required" implied user action when in practice the integration
auto-recovers via the wake_first send path. The bit is actually a
transient low-power / sleep flag — it cycles off during motor activity
and back on once the motor settles. Renamed end-to-end (decode key,
coordinator pop list, cover._needs_wake, binary_sensor key +
translation_key, English string) to "low_power_mode" / "Low power
mode". Dropped device_class=problem since it is no longer a problem
the user must respond to. Kept entity_category=diagnostic.

Subject: [PATCH 08/16] coordinator: derive cover direction from position
 delta, not advert bits
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The V2 advert encodes is_opening / is_closing in pos & 0x3 (0x2 and 0x1
respectively). Empirically, at least some KDT curtain firmwares swap
those bit meanings vs ACR rollers — symptom was HomeKit displaying
"Closing" while a KDT curtain was physically opening, even though the
position field was climbing from 0 toward 100 the whole time.

Position itself is unambiguous. After updating self.data with the decoded
V2 fields, compare the new ATTR_CURRENT_POSITION against the previous one
and override is_opening / is_closing accordingly:
  * new > prev  ->  is_opening = True,  is_closing = False
  * new < prev  ->  is_opening = False, is_closing = True
  * new == prev ->  both False (shade is stopped)

The advert bits are now ignored for direction inference. The is_closed
property still drives the steady-state "open" vs "closed" classification.

Verified live on KDT:3F34 (Master Bedroom Curtains), which was
previously showing "Closing" in HomeKit while opening: post-fix the
state trace is closed/0 → opening/44 → opening/95 → open/100.

Subject: [PATCH 09/16] cover: kill ghost state transitions

Two fixes that eliminate the "closed -> closing -> closed" and "open ->
opening -> open" ghost transitions observed during normal HomeKit use:

1. is_closed uses the same DIRECTION_DEADZONE (currently 2%) that the
   movement properties use, so motors that settle 1-2% short of fully
   closed (common end-of-travel calibration drift) no longer bounce
   between "open" and "closed". Now also correctly returns None when
   position is unknown, instead of falsely reporting "open".

2. The three command handlers no longer call async_write_ha_state() at
   the end of their BLE round-trip. The integration's coordinator
   already calls async_write_ha_state on every BLE advert via the
   PassiveBluetoothCoordinatorEntity update path, so position and state
   stay live. The optimistic post-BLE write was racy: a stale-position
   advert arriving during the ~500ms BLE round-trip caused the entity
   to write inconsistent state (e.g. "closed" at command time when
   target was 0 and position was momentarily reported as 0, before the
   real position re-asserted itself).

Verified live on Baby Room Roller (cover.acr_a67c_shade):
  pre: state=closed pos=0
  HK open(100): one brief "open" transient -> "opening" solid 20s with
  smooth position updates (0 -> 3 -> 6 -> ... -> 96) -> "open"/100.
  No more closed/closing/closed oscillations.

Subject: [PATCH 10/16] cover: write moving state before BLE await to keep
 HomeKit TargetPosition stable
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

HA's HomeKit Bridge resets the HomeKit accessory's TargetPosition to
CurrentPosition whenever the cover entity is *not* in a moving state
(see homeassistant.components.homekit.type_covers.OpeningDevice.async_update_state).
The previous patch removed the post-BLE optimistic write to kill ghost
"closed -> closing -> closed" transitions; the side effect was that
during the ~500ms between async_set_cover_position being entered and
the next BLE advert arriving, the entity could appear in HA as state
"open" or "closed" with the new target already set. The Bridge sees
that brief non-moving frame, clobbers HK's TargetPosition to match
CurrentPosition, and from that point onward iOS computes direction
from (Target - Current) and displays it backwards for the rest of
the move — e.g. "Closing..." for the entire physical open.

The fix is to write state once at the moment the command is registered,
*before* the BLE await. With _target_position set, is_opening / is_closing
already report the correct direction, so the entity immediately enters
"opening" or "closing" and stays there until the next BLE advert
recomputes (and stays in the same moving state because target hasn't
been reached yet). The Bridge never sees a non-moving frame during the
move, never overrides Target, and iOS displays the user's intent.

Verified live on Master Bedroom Curtains (cover.kdt_3f34_shade) from
state=closed/0 to fully open:

  +0.5s   state=opening pos=0      <-- immediate, before BLE round-trip
  +1.0s   state=opening pos=2
  +5.0s   state=opening pos=45
  +10.0s  state=opening pos=93
  +11.0s  state=open    pos=98     <-- within DIRECTION_DEADZONE of target
  +11.5s  state=open    pos=100

No "open" transient between command and "opening", which was the frame
the HomeKit Bridge was latching onto.

Subject: [PATCH 11/16] cover: pin direction during command + skip coordinator
 updates while pinned

Adds two defenses against the race where a BLE advert arriving in the
same event-loop tick as a HomeKit set_cover_position would otherwise
write a non-moving 'open'/'closed' frame that trips HA's HomeKit Bridge
into clobbering HK's TargetPosition (which then makes iOS display the
direction backwards for the rest of the move).

1. _pinned_direction attribute and _pin_direction(STATE_OPENING |
   STATE_CLOSING | None) helper. is_opening and is_closing check the
   pin first and return True unconditionally when set. Pin is set at
   the top of every command handler and cleared in a finally block.

2. Overridden _handle_coordinator_update that short-circuits while a
   pin is set, so BLE adverts arriving mid-command can't fire an
   async_write_ha_state that would overwrite the entity's pinned
   moving state.

Also widens is_closed deadzone (ENDPOINT_DEADZONE = 5) so brief
position-noise adverts that report 3-4 from a settled-closed shade
don't flip the entity from 'closed' to 'open' right before a command.

NOTE: when the advert handler is scheduled in the event loop *before*
the command handler, the first non-moving frame still gets written
before _pin_direction has been called. The cluster of state writes
that result are within microseconds of each other and HK Bridge's
Target reset still happens on the leading 'open'/'closed' frame.
This commit shrinks but does not fully eliminate the window. See
PR thread for follow-up discussion.

Subject: [PATCH 12/16] cover: pin direction synchronously from
 homekit_state_change event
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

HA's HomeKit Bridge fires the `homekit_state_change` event SYNCHRONOUSLY
inside its TargetPosition setter callback, before the
cover.set_cover_position service-call task is queued onto the event
loop. Subscribing to that event from the cover entity lets us pin the
direction and pre-set the target in the same synchronous frame that
iOS triggered the command from, beating any racing BLE advert that
would otherwise fire async_write_ha_state with a non-moving state and
trip the Bridge into resetting HK's TargetPosition (which flips iOS'
direction label for the entire move).

Only set_cover_position events on this entity are handled; everything
else is ignored. The pin is still released in the command method's
finally block — the listener just guarantees it is set early enough.

No HA core changes — the event listener lives entirely inside the
integration.

Subject: [PATCH 13/16] cover: separate "can command" from "data fresh"
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Previously `available` was gated on `data_available`, which checks
that a V2 advert was decoded within STALE_AFTER (30 min). ACR rollers
back off their advert cadence after a few minutes of idle and may
not transmit again for hours — they still accept BLE writes the
entire time and wake on command. Gating availability on advert
freshness made HA refuse to dispatch service calls when the user
tapped the shade in HomeKit / Lovelace / a script, logging:

  WARNING (MainThread) [homeassistant.helpers.service] Referenced
  entities cover.acr_3cf2_shade are missing or not currently available

When the `homekit_state_change` listener fired and pinned direction
but the service call was dropped, the pin had no command-method
finally block to clear it, leaving the entity stuck at "Opening..."
in HomeKit and the motor unmoved.

Fix splits the concern:

  - `available` now only checks `super().available` (BLE address
    reachable). The shade is always controllable.
  - `assumed_state = True` when data is stale, so HA's UI shows the
    "assumed" indicator without blocking commands.

Also adds `_pin_is_valid` as a defense-in-depth backstop: the pin is
honored only while `_target_is_fresh()` (i.e. within TARGET_TTL of
the last command). If anything else slips a stuck pin past the
command method's finally (unhandled exception, future code paths),
the entity falls back to advert-derived state after 60s instead of
showing "Opening..." forever.

Removed three blocks of debug logging that were left behind from
diagnosing the earlier race (per-property is_opening / is_closing
/ is_closed debug + traceback dump in async_write_ha_state). Kept
the listener; trimmed its docstring to a single block.

No HA core changes.

Subject: [PATCH 14/16] cover: hold opening/closing state until motor settles,
 not just deadzone

Previously is_opening / is_closing returned True only while
|target - current| > DIRECTION_DEADZONE (2%). On a 0->100 open, that
flipped to False the moment the motor crossed pos=98, leaving a "open"
state frame written while the motor was still physically running its
last few percent. HA's HomeKit Bridge clobbers HK's TargetPosition
whenever the entity is reported in a non-MOVING state (open/closed),
so that single transient frame at end-of-move flipped iOS direction
label backwards for the rest of the move.

Replaces the deadzone with a "motor settled" check:
- record the wall-clock timestamp of every position change in
  _handle_coordinator_update
- is_opening / is_closing return True while target != current AND
  _has_settled() is False (last position change within 1.5s)
- once the position is stable, fall through to the normal open/closed
  evaluation

Live trace, Guest Room Roller 0->100:

  closed -> opening (call_service)
  ... 25 advert frames at "opening" while position rises 0->100 ...
  open (settled)

No "open" or "closed" transient between the moving state and the
final state. TargetPosition stays whatever iOS asked for, direction
label stays correct.

Subject: [PATCH 15/16] cover: _has_settled must require a position change
 AFTER the command
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Previous version of _has_settled treated a shade that hadn't moved in
hours as "settled" the instant a fresh command landed. The next BLE
advert (still at the pre-command position) would arrive after the
command method's pin had been released, fall through is_opening /
is_closing to is_closed, and write a non-moving "open"/"closed" frame
*while the motor was just about to start*. HA's HomeKit Bridge
clobbers HK's TargetPosition on any non-moving frame, flipping iOS
direction label backwards for the rest of the move.

Fix: _has_settled now returns False if _last_position_change_ts is
older than _target_set_at. The motor hasn't reacted to the command
yet, so we are explicitly NOT settled — keep is_opening / is_closing
returning True until the first post-command position change starts
the SETTLED_AFTER countdown.

Diagnostic trace (Kitchen Small open from closed, before fix):
  T+0.000  state=opening pos=0  (my command method)
  T+0.845  state=closed  pos=0  (BLE advert + ghost!)
  T+0.958  state=closed  pos=0  (BLE advert + ghost!)
  T+1.178  state=opening pos=2  (motor started, recovers)

After fix:
  T+0.000  state=opening pos=0  (command method)
  T+0.451  state=opening pos=0  (BLE advert, NOT settled — pos change
                                  ts < target_set_at, returns False)
  T+0.670  state=opening pos=0  (same)
  T+0.780  state=opening pos=2  (motor started)
  ...                            (continuous opening through pos=100)
  state=open                     (settled after motor stops)

Subject: [PATCH 16/16] cover: filter spurious position jumps > 50% in a single
 advert

The shade BLE module occasionally emits a stray pos=0 init/boot advert
(resetClock=False) when the motor settles, and flaky BLE proxies can
re-broadcast a stale all-zeros beacon mid-motion. Either source lands
a single advert with a physically impossible position delta between
two real frames.

On a 100->70 close, that frame was triggering:

  T+0.000  state=closing pos=100  (command)
  T+0.044  state=closing pos=100  (advert, motor not moving yet)
  T+0.096  state=closing pos=100  (advert)
  T+7.893  state=opening pos=0    <-- spurious advert, real motor at ~70
  T+8.113  state=open    pos=70   (good advert, motor settled at 70)

The "opening pos=0" frame fires because target (70) > current (0), so
is_opening returns True. HA's HomeKit Bridge stamps the HK
PositionState characteristic as INCREASING for that frame and iOS
latches the "Opening..." spinner until the next motion - despite the
shade being correctly settled at 70 in HA itself.

Reject single-advert jumps larger than MAX_POSITION_JUMP (50%):
- 50% is well above plausible motor motion between adverts (~7%/sec
  for ACR rollers means even a 5-second gap caps real change at ~35%)
- Rejected adverts don't update _last_position so the next good
  advert is still judged against the last *good* value (e.g. 100,
  not the rejected 0)
- We return early before super()._handle_coordinator_update so no
  state write fires for the spurious frame - HK never sees the wrong
  direction

Behavior unchanged for the common case: every test run that didn't
hit a spurious advert continues to write state cleanly through the
move.
