Hey everyone, I know I’m replying to an old thread, but it looks like no one really found a solid solution. I bought a Tado system last week and ran into the same issue while setting it up. In my case, the Bridge connected to my Meraki Wi-Fi without any problems. However, whenever I tried to connect and pair the wireless temperature controller, it failed every single time. I was pulling my hair out trying to figure out how the thing communicates. I went through this thread and applied everything that was suggested,  a dedicated 2.4 GHz IoT network, disabled Layer 2 isolation, and even created a rule in the Meraki Wireless Firewall & Traffic Shaping section to allow IPv6 traffic from “any” to the local LAN. None of that worked. What finally solved it for me was enabling Bonjour and adding a rule to allow Bonjour discovery for all services. As soon as I applied that, the wireless Tado temperature controller paired without any issues. I don’t use VLANs on my local network, so when creating the Bonjour rule, just select VLAN 1, which is the default in most cases.     Hopefully, this helps someone else dealing with the same problem. ...
