Only 2/3 TRVs open when maintaining temperature?
I have the temperature in a room with 3 Tado TRVs and a wall thermostat set to 19.5 C. As I write this, the temperature in the room is 19.7 C and the heat request indicator in the app is showing 2 wavy lines, but only 2 of the 3 TRVs are open. The third radiator, which was hot maybe 30 minutes ago, is now cold.
Is this normal? Is it how Tado optimizes energy consumption or do I have a faulty TRV? (The app says the TRV is connected and the battery is good.)

As your target temperature is reached as expected I’d say it’s normal. In the room I have with two trvs they tend to open and close in sync but assuming all your trvs are set in the same room on the app, Tado might be aware that the rad it has switched off reaches target temperature quicker than the other two. Or it may just be shutting it earlier to better control overshoot.1

I genuinely don’t know. But if it’s reaching target temperature it’s clearly doing something right. Of course if the third rad is never coming on then that’s a problem.0

Basically the same situation triggered my question: https://community.tado.com/en-gb/discussion/17239/2-trv-in-the-same-room#latest0
