As @skender85 has already pointed out, the Ally room sensors are only temperature sensors. However, in combination with the thermostats https://www.galaxus.ch/de/s2/product/danfoss-ally-thermostat-13686149, or the StarterPack Danfoss Ally Starter Pack, control can be realised. Alternatively, the Allys can also be integrated into a home automation system such as OpenHAB or HomeAssistant via ZigBee, e.g. via RaspBee Dresden Elektronik RaspBee II or ConBee USB stick https://www.galaxus.ch/de/s1/product/dresden-elektronik-conbee-ii-usb-stick-smart-home-hub-11045397.

With this item and the associated Danfoss Ally Starter Pack , the temperature can be controlled very precisely.
