Drayton Wiser heating

Just buy Wiser. It works really, really well, it can operate without a cloud service, you can integrate it with Home Assistant to add layers on top of the base system and you have a warranty and tech support if you should need it. About the only downside is hanging a(nother) Zigbee network fighting for frequency space alongside your WiFi and any other Zigbee you might already have. Heating is important. Home brew is nice, but you can guarantee it will go wrong or need attention at the worst time - this is an area where an established ‘appliance’ makes sense.
