Pod 4 / FreeSleep degraded state: SQLite readonly + SSH unavailable + feature failures

[RevoGap]

Device

Eight Sleep Pod 4 running Sleepypod (before yesterday, running FreeSleep)
Local IP: 192.168.178.29
Device reachable on LAN

⸻

Summary

Device is reachable and core services are running, but multiple system features fail due to persistent database write errors and missing SSH access.

⸻

Network / access state

• Ping: OK
• SSH (port 22): Connection refused
• Web UI: OK on port 3000
• WebSocket/API: OK on port 3001

nmap result:

• 111/tcp open (rpcbind)
• 3000/tcp open
• 3001/tcp open
• 22/tcp closed (connection refused)

⸻

Live backend behavior (3001 WebSocket)

Device stream active and stable:

• Temperature reporting normal
• Water level: OK
• Left/right systems active
• No hardware faults observed

⸻

Core error (repeated)

SQLITE_READONLY: attempt to write a readonly database
DeviceStateSync: failed to write device_state
DeviceStateSync: failed to write water level

⸻

Impacted features

• HomeKit integration fails
• Sensor calibration does not work
• Gestures / presence detection fail
• Device state changes do not persist
• UI operates but state updates do not save

⸻

Observations

• System is partially functional and continuously streaming state
• Scheduler and services reload normally
• No evidence of hardware failure
• Issue appears related to database write permissions or filesystem state
• SSH service not running or not present in current runtime state

⸻

Suspected root cause

Likely filesystem or SQLite storage mounted read-only or corrupted, causing persistence layer failure and disabling dependent services.
