Hi all, I’m new to Home Assistant. Hopefully I’m not being ignorant of something, but I’ve been all over all the docs I can find, and I’m unable to answer a question -
I’m working on integrating Home Assistant and a custom lighting controller I’ve built. The controller should ideally subscribe to a few MQTT topics to get configuration from HA. I’ve seen the light device here, and it is very close to what I’d like to achieve, but it’s not a perfect match. The controller I’m working on has a lot of custom effects with parameters I want to control via sliders.
My question is this: is it possible to make a composite device from various MQTT entities I’ve defined in configuration.yaml? I have successfully been able to control the device as a switch, but I would like to expose more configuration all under one logical device. My hope is that clicking this device in HA can show a bunch of fields like when I click an RGB light in HA.
For clarity, I’m hoping to do this entirely via configuration.yaml or other configuration files. I’m sure this can be achieved by creating an HA add-on, but I’m guessing that’s a lot of work, and I’m not very keen on getting a development environment set up to make on device that is hardly more than an RGB light.
