I did not really find it via search, so I will address it here. Thank you in advance!
New building in Germany
Approximately 10 thermostats necessary
Smart functions would be great
Battery or connected to the electricity: I’m still unsure
For our new building I am looking for nice thermostats. Our electrician proposes TADO and HOMEMATIC. As far as I know and find, Homey supports TADO. Here, however, comes to me negatively that you probably have to pay subscription fees to TADO, if you use smart features … Is that the case even if Homey managed the “smart functions”? Homematic I think so far not supported by TADO (search on the thermostat page).
What would have liked so far is “ThermoSmart from Thermosmart B.V”. However, I find little technical information or a real purchase option. Seems to be very expensive too.
Visually, I find “https://www.athom.com/en/store/product/plugwise-anna-thermostat/” very interesting and also priced at 99 € / piece. Has anyone had experience with it? The technical data are unfortunately not very detailed (well, I’m also a layman) but I can not see if they send their signal via WiFi and need batteries or need to be powered by 12V or 230V. Do the Anna - Thermostats ONLY work with Tado or would they work on their own, if Homey should not exist in 5 years, etc …
I am really happy about your answers and experiences. Our electrician wants to get in touch as soon as possible … Thank you, Franz
