I have inherited this problem on exactly two tiles - both generic Z-Wave switches. They always show “Off” but operate the switches properly. The other 41 tiles on the dashsboard exhibit no problem. I have tried refreshing SharpTools, unauthorized and reauthorized the devices, and have power-cycled everything but the washing machine.
The problem began yesterday coincident with the installation of a second HE hub, and my discovery that the two hubs were not going to play nice with SharpTools. None of my existing devices have ever been connected to the second HE hub.
