MQTT RGB light error

Configuration
1

I’ve built my own wifi/MQTT lights using an esp8266-12e and some neopixels. I used this library: Melvanimate

Can someone help me, I’m getting this error in the logs. I think I just need to set a template to massage the data how HASS wants it.

There’s a list comprehension here: https://github.com/home-assistant/home-assistant/blob/dev/homeassistant/components/light/mqtt.py#L148 which attempts to make a list of integer values, notice the int(val). The problem is that the val is ‘[16’ which cannot be converted to integer. You probably have to do some debugging and see why val is taking that value. I’d probably add some print statements and see what is in templates[‘rgb’] in the first place, then check payload and so on.

I know this is an old topic, I was wondering if you had any more luck with MQTT, esp8266 and some ws2812B (neopixels). I am curious about making something like this with some NodeMCU’s but I am a programing fool!
Thanks!

Are you still looking for this? Because I have done it.

Definitely still interested!
