Rungtime error: index out of range [0]

[sliemen]

I keep getting this error when I'm trying to create a connection between Digitalstrom and HomeAssisstant.

It only happens when I use the following parameters: HOME_ASSISTANT_DISCOVERY_ENABLED=true HOME_ASSISTANT_DISCOVERY_PREFIX=homeassistant

panic: runtime error: index out of range [0] with length

Thanks for the report. It seems that this piece of code is trying to access the first output channel of a light item, but apparently the light item has no output, which is weird. Can you list the type of light devices you own please (ex GE-KM200).

I'm using Philips Hue lights that are connected to Digitalstrom in a test setup. See following output:

Thanks a lot, that helps ! I can see "OutputChannels\":null for the Hue. I will try to come up with a patch this week or the next one. I will post here when I realease it.

Thanks!

Release 1.6.7 is out. I don't use Home Assistant, so I hope it helps I wasn't able to properly test.
