Only Device I found is Shelly TRV but with my own valve automation my Temperature Control works better than with customers. But than I don‘t need such an expensive Device.
Maybe someone has an goog Idea for such an Device.
Sorry for the delay but I only had problems with Tuya devices in the past. And I don‘t want to use there cloud or hacs Integration. Iot devices shouldn‘t communicate with outside world.
And as I know you only can control them by temperature not valve position. And all devices I tested in the past there pid control is not very comfortable
