@Wayne-TP I can link one temperature sensor to one KE100, but I can link multiple contact sensors to one KE100. sleeping room: 2x T110 (two windows) and 1x T310 linked to one KE100 Living room: also...

@Zenoxi Thx. But Wayne TP is also right: see his Post#2. That's the way to go, if your are using the Kasa App. What you need in this case: KE100 + KH100 (Hub) + Sensor, for instance: T110, T310/ T315...

@Zenoxi You can contact Support also in Tapo App: Me>Help& Feedback>Others>Feedback

@Zenoxi Disclaimer: I'm not an TP Link employee nor working for TP Link. I'm also only a simple costumer. So I can't answer your question. Please contact your local TP Link Support Team. Thx.

@Zenoxi Thats what I wrote before: Account and/or Country (Region) related issue, not an Tapo App issue.
