Connection Issues

[CFenner]

Describe the bug

See https://github.com/lkempf/casambi-bt-hass#reporting-issues on how to enable logs. Please make sure to at least include the log of the first connection with the network (be restarting HA or reloading the integration) and the log at the time an error happens (if applicable).

This stack trace is incredibly weird so not sure if I will be able to help. I've added some additional error handling to casambi-bt and plan to test the changes sometimes this month. There's a slight possibility that these might help. I'll notify you when a new release with them is ready.

I'll also try to reproduce the error by switching the bluetooth adapter into debug but this will have to wait until I have enough time at my parents house.

[CFenner]

Anything I can do by now?

[lkempf]

Sorry I haven't had the time to look into this properly yet.

[lkempf]

Ok I at least can't reproduce this by manually turning on debug logging. Can you report back if this is still happening with v0.1.0?

[lkempf]

Is this still happening or can I close it?

I am regulary having a similar connectivity issue.

after countless restarts of HA or the Add on it gets back on track at least for some time, then back to start..

[CFenner]

Is this still happening or can I close it?

I think the issue still persists on my side. The room where I have the lamps is not used during the winter 🥶 so I do not know how it is currently.

[lkempf]

@schoenis Your error looks like a simple bluetooth issue. Have you tried decreasing the distance between your bluetooth adapter and the network?

[macflei]

Vielleicht hilft es ja auch dem ein oder anderen. Passives Scannen scheint bei mir das Problem mit den sporadischen Verbindungsabbrüchen behoben zu haben. Seit über 48 h scheint die Verbindung stabil zu sein. Vorher hatte ich am Tag auch immer zwischen 10 und 20 Verbindungsabbrüche und es half nur ein kompletter Systemneustart.

mein HA-Testsystem: RasPi 4 Bluetooth: intern vom Pi Core: 2024.3.3 Supervisor: 2024.03.1 Operating System: 12.1 Casambi-Integration: v0.1.1

[CFenner]

Wie stellst du auf passiv um?

I switched on my Casambi in the last days and changed BL connection to passive. Indeed it seems to be stable now.

[Alexei-vk2]

Hello! Faced with this situation: Casambi integration is installed in the home assistant. when the "unavailable" condition occurs, the lights turn on and off.

is there any way to make sure that even after the "not available" state, the devices have the last mode so that they are turned off? can you tell me how to do this?

[Zubredo]

I switched on my Casambi in the last days and changed BL connection to passive. Indeed it seems to be stable now.

Unfortunately, this does not solve the issues with my setup.

My Hardware Home Assistant Yellow with a Realtek Bluetooth 5 Stick.

Versions Latest (HA Core 2024.10.4, HA OS 13.2, Casambi Bluetooth 0.1.3)

Bug Description The Casambi Bluetooth integration looses connection with my occhio lamp every 24h-48h. After that only a restart brings the connection back. Change Bluetooth adapter to passive scan does not seem to stop the connection errors.

From the error logs it seems that the integration somehow messes with the bluetooth hardware. It says that the bluetooth adapter would not exist anymore.

Furthermore, the logs are saying _"[CasambiBt.client] Version too new. Your network version is 11. Highest supported version is 10. Continue at your own risk." No idea what that means.

Any Suggestions how to solve the issue?
