Extension kit shows no access
My system is currently in away mode. I have just checked and all my radiator valves except one are showing no remote access. However sharpen I look at the system it appears that the only device without access is the extension kit. That is the only device with the red exclamation mark. It would appear that it is the extension kit that has lost access either with the bridge or with the main thermostat . What is going wrong, This is the second time that the extension kit has lost access. What should it connect with the bridge or the thermostat, should it need repairing or what.
