No Audodiscovery and no Play/Stop

[ValiEne]

Hi,
First I want to thank you for sharing your work with us.
I've tried to add my cats' Petoneer Dot but unfortunately I didn't succeed.
I'm running HAOS on an Intel NUC machine which has a buildin BT adapter that works fine.
When adding the Integration I'm unable to auto-discover the Dot so I'm adding it by manually entering MAC address, which works, or at least it looks like it's working.
When clicking the Play button I can see in the logs something like this:
2024-04-26 15:48:49.254 DEBUG (MainThread) [custom_components.petoneer_smartdot.button] Current game mode: medium 2024-04-26 15:48:49.254 DEBUG (MainThread) [custom_components.petoneer_smartdot.button] Connecting 2024-04-26 15:48:49.870 DEBUG (MainThread) [custom_components.petoneer_smartdot.button] Sending command 2024-04-26 15:48:49.871 ERROR (MainThread) [custom_components.petoneer_smartdot.button] Connection: BleakError: Characteristic {char_specifier} was not found! 2024-04-26 15:48:49.964 DEBUG (MainThread) [custom_components.petoneer_smartdot.button] Disconnected

I'm doing something wrong or what else should I try?

Thanks

Hello. The fact that your Petoneer SmartDot is not discovered through discover and the subsequent error in sending the command most likely indicates that there are several different firmware modifications for the SmartDot at Petoneer.

I was basing this on data from Marco Colombo from the hass-addon-petoneer-smartdot.

I actually just had my toy break and I've ordered a new one. I'll pick it up today and check if its firmware is different. If so, I will make changes to the code and at the same time ask you to provide additional data for debugging. I will show you how to scan Bluetooth devices so that you can see the SmartDot identifier and the service it provides.

Thanks Vadim, no hurry :)
Let me know if you need any info from my side

I received the new Petoneer Smart Dot and unfortunately, the manufacturer has significantly changed the protocol in the new firmware. The previous Petoneer SmartDot was model PTY010, the new one is TY011.

The previous model had firmware version 1.09, while the new one has 1.2.

Old

New

The controller board has also visually changed:

Old

New

I attempted to debug the new protocol, but unlike the previous version, the packets that the phone app sends to initiate various types of games are no longer static. Each time, the app sends new data when accessing the Smart Dot. When I tried to send a packet with the same content through a Python script, nothing happened.

I wrote to Petoneer support, but I'm afraid they won't provide me with the protocol documentation.

In my case, I simply swapped the controller board from the old model to the new one. Everything worked, except that the eye's centering was slightly off. It looks a bit to the side from the center in its default position, but I'm willing to live with that.

I'll leave the issue open, perhaps Petoneer will respond. For now, I'll add a note in the README about the supported firmware type.

I'm very sorry that the manufacturer changed the firmware of the device, thereby complicating the integration of the Smart Dot into Home Assistant. However, they did not add any functionality to their app.

Thanks a lot Vadim for your time.
My board looks similar with the new one you got - I've opened the case few months ago to swap the BT module with an ESP one running Tasmota but unfortunately it didn't worked and I had to roll back to default module.
Later edit: this is what I've tried and failed: https://templates.blakadder.com/petoneer_TY011.html

Looking at the components on the board, it resembles my board from the new version of the Smart Dot, but it still differs. Your board has a marking with version v0.20. It seems that Petoneer has changed the controller board more than once.

I also looked into replacing the Bluetooth chip with an ESP32 and the project at blakadder, but I was lucky with my board. Now that I have a new controller in hand, I might try to replace the chip. If I manage to do it, I will write additional information about it.

I will also post in this issue if Petoneer support responds.

getting the same error, I was very excited but I guess I am also on the new version of firmware problem, correct?

[verdel]

I think you also have the new version of the model, where the manufacturer changed the interaction protocol by adding encryption.

A little earlier in the issue, it's described how to distinguish the old version from the new one.

Bummer. I will try a way with Bluetooth gateway works with Tuya. Hopefully I can get it working with that on HA. It is important for me to be able to operate it outside network. I exhausted my tries with direct Bluetooth...thanks

[verdel]

I was lucky that I got an old model, and when the previous toy broke, I just transferred the controller to the new version. The center of the eye shifts slightly, but it's not significant.

Unfortunately, I still haven’t found a way to work directly with the new version of the controller and firmware.

[fate8383]

I wonder if Bluetooth gateway will help...they are not expensive but they are used mostly for temp humidity sensors with blue...not sure if this will work with it...waiting for delivery.

[verdel]

I use ESP32 board like this with ESPHome firmware as a Bluetooth Proxy for HA. However, the Bluetooth Proxy will not solve the problem if the Petoneer itself uses a controller with a new firmware version. In that case, my plugin still won't be able to control the toy.

[fate8383]

hey ble gateway for Tuya, size of a box of a match, worked perfectly. I am able to operate it remotely now with full functions with Tuya app. I will explore more possibilities to go local via HA but that's complicated already. I see DPs but not recognized with any existing integrations yet. Even official Tuya integration finds it but says unsupported...

[fate8383]

success. with local tuya fork integration it works by adding sub device and its DPs. Now fully local homeassistant controlling and HomeKit as well.

[verdel]

@fate8383, great! I’m very glad that you were able to connect the Smart Dot to HomeAssistant and HomeKit.
Could I kindly ask you to check which model is indicated on the bottom of the Smart Dot (TY011 or PTY010)?
Also, could you describe in a bit more detail how the Smart Dot appears in the Tuya App and in HomeAssistant?
