Hi! I bought a couple of these switches to install in my system, they are matter but they are wifi... should I add them directly in hubitat app (and how, because adding the matter 11 digit code is not working) or I should add it first to the tapo app and later to hubitat? Zwave and Zigbee was much easier!
You need to commission them with apple, google, or echo. Once commissioned you can generate a code to add to hubitat. That said, because bluetooth is needed to commission, once the hubitat app is given the ability to use the bluetooth radio in your phone, you will be able to commission directly to hubitat.
Hubitat's mobile apps don't (currently) take advantage of the Bluetooth in your mobile devices, so to pair a Matter device, you'd need to start with an Apple, Google, Amazon device that can use the Bluetooth in your device, then you can generate a pairing code from those controllers to allow the Hubitat hub to add the device without using Bluetooth.
