Thermostat swap danfoss

BurkieDaddyo

I have danfoss tpone-m two zone thermostats in my home but they do not have access to the Mobile app. I want to get access to the app and wondered if it’s as simple as swapping out the old thermostats for newer. Danfoss tpone-s thermostats for example. Or do I need additional changes to make the app available (receivers)? I want to keep the same size and style thermostats so there is no mess when they have walked out on the wall. Thanks in advance for any help or advice.
