I basicly have the same question. Got 11 rooms with TRVS and one thermostat downstairs. Multiple zones. Is there, by NOT using the app, a way to turn al TRVS off using the thermostat.
Click on the "Home" button and set the status to "Away".
(not sure about exact wording as I have another language)
Have a look at IFTTT app on your phone. People have made Tado 'applets' that allow you to add one button widgets on your home screen to turn all heating off and/or all heating on - (on Android). There are many other decent things you can do with IFTTT and Tado. It's quite simple to use.
The Tado thermostat is a minimalistic design that can do almost nothing. The system is designed to be used from the app or the browser.
