On/off toggle causes python exception

[valerii-fr]

Hello, I'm using AliExpress kits with following SNs:

• LEDnetWF0200A3628247 (8247)
• LEDnetWF0200A3620557 (0557) And having stacktraces like this if I try to toggle on/off switch or change some modes. Brightness, animated modes and color picking work well btw.

HA is installed in a docker container if it matters.
I'm going to try to research this issue but it will be my first python expreience, so, don't look forward to hear sth useful from me soon  :)

no idea why, but now it works

Glad you fixed it! How do you have bluetooth support on docker HA? Are you using esphome proxys?

[valerii-fr]

Just reproduced again :( No correlation with environment for now

No, I don't use proxying, i've mounted dbus and use bt dongle

Give this branch a try: https://github.com/raulgbcr/lednetwf_ble/tree/8none1/new_models

Check #18 on how to install it

[valerii-fr]

It fixed my problem, thanks! Will report if I have any issues with test branch

[8none1]

I'm reasonably sure that I hit this in the past and that branch should indeed have a fix for it. Sounds like it does. :+1:

[8none1]

Actually, I'm wrong. I can see the bug now. I will address it in the feature branch.
