Add WiFi support to Extension kit to get rid of bridge
Seems a logical option for those folk who have a full Tado installation with HW control.
Add WiFi support into the Extension kit since it's mains powered. This would remove the need for (and failure risk of) a separate bridge
This would almost certainly need to also include an upgrade to mesh capability as many extension kits will be located at the periphery of properties i.e. utility rooms, kitchens
