Hi,

I'm looking at getting either this model, or the Tado. The Tado gets good reviews, but pairing it with a separate thermostat would be expensive as the Tado option (rather than the Tapo T310) is £80 a pop. 

Also, I prefer the Kasa approach of not having to remove the whole valve head to replace the batteries.

One question: the temperature range quoted is 0 - 40. So, can you set the temperature selection for the thermostat valve up to 40? The Tado goes up to 25.
