I think the best thing to do is wait for https://github.com/8none1/zengge_lednetwf to be added to flux_led and led-ble

Hi @bdraco,

I’ve bought this LED Strip which is also some kind of Triones device that gives the same error as @SunilKhusal reported. It is discovered by HA right away but gives a Failed to Connect error upon connecting with the same CharacteristicMissingError error in the stacktrace.

If you could let me/ us know how I can execute the script in HA, I’m more than happy to do that. I already tried it in the HA Core container but that doesn’t work because python does not seem to be available in the terminal (or I’m wrong).

Thanks in advance! Wesley
