First of all make sure that your devices are in the proper rooms in Thinka. Our ETS import helps you recognise devices and rooms. Alternatively you can do this manually. See this video on Thinka's video channel for more help configuring rooms.
When you are happy with your devices and rooms, you may use the Thinka Setup app from the Apple Appstore to synchronise your Thinka with HomeKit. This way you do not have to manually put all your devices in their rooms again in Apple's Home app.
