I just got my Hubitat last week and have since connected with 20+ WEMO devices. I have three WEMO Makers, but only one of them is showing the contact under Current State, and the contact state is incorrect (shows 'open' no matter what the connected switch state is). The other two WEMO Makers don't show anything for contact status.
All three are using WEMO Maker driver provided by janson0x43. I have reset all three of these WEMO Makers, they are all connected to the Hubitat and responding to switch commands.
