-EQ-3 radiator valves work really well for a home-automation heating system. They are fully configurable vie BLE as well as their front-panel. There are more options available than the calorBT app makes available.
+EQ-3 radiator valves work really well for a home-automation heating system. They are fully configurable vie BLE as well as their front-panel. There are more features on the valves than the calorBT app makes available.
 
-The main problem with centrally controlling them is the limited range of BLE. This makes it impossible to use a single central-controller to talk to all TRVs in a typical house. Therefore multiple 'hubs' are required at distributed locations.
