Please be aware, the Viessmann Climate Sensor moves all control of your boiler to the ViCare App. There is no in-home control of heating or hot water.
This means if you have internet connectivity issues you will temporarily lose connection to your boiler.
If you would prefer a physical thermostat for your new boiler in your home the Viessmann Vitotrol 100-E smart thermostat will be a better option. However it is only available on the 100-W and 111-W series boilers for now.
