Problem pairing extension kit
I had a problem pairing the extension kit. I was holding the pairing button on the extension kit (for 4 seconds) and it failed to pair with the internet bridge.
FIX: I learned the correct pairing procedure is to press the pairing button on the internet bridge AND the extension kit. Both these devices must be in pairing mode at the same time for the extension kit to pair.
Suggestion to Tado: This correct procedure was not made clear in the user instructions. Instructions on this process should be improved on the online web portal.
