I’ve built a new custom integration for Arduino RFLink gateways that finally replaces the old YAML-based setup with a modern, fully UI-driven experience.
its completelly indepedent from the yaml config from rflink, its all trough UI
and (for your second question) technically i did not plan to add that because i have nothing to test with but it could be a thing yeah
I guess RFlink users will often use binary_sensors for things like doorbells, lights for kaku* devices. I was/are using all domains at some time. I'm not sure about the amount of coding this would add, but most RFlink controlled domains seem to have similar controls.
If you want to add other domains, I could help you test them.
