“Would give it 0 stars if I could, It does associate with the z-wave controller and does report the temperature from its little thermometer but thats as far as it goes. Every 10 mins it tries to calibrate the valve, remove it check it, replace it, same happens every 10 mins or so, battery only lasts a few days because of this. We have eurotronic spirit valves on the other radiators that just work, you can see the temperature and the batteries last 6 months+. My mistake but somewhat annoyed with myself”
