At first glance, none of these support Zigbee which would be the optimal. But OK. Which brand should I trust the most in terms of great HA integration, no cloud and app requirements?
I can’t speak to any of the others, but I’m using RainMachine successfully. I have cloud disabled and it works fine locally over WiFi. For the most part I let RainMachine control nearly everything itself because it’s good at that and I prefer devices running their own mission so they continue to operate in case Home Assistant or the WiFi goes offline. I have one sprinkler zone that I control from Home Assistant to fill my pool, which works great.
