Time to say thank you to HC3 – and I switched to Home Assistance. HC3 only started working for me as a receiver. The amount of integration I can do with Home Assistance compared to what I've believed in for over eight years is a bit excessive. In my opinion, it's a dying system, light years ahead of others. Thanks to everyone for the good suggestions on switching to something that makes more sense these days. I won't regret Fibaro.
