I have three nest thermostats installed my house, one per level. I use a VERA 3 with UI7. When I upgraded to UI7 and installed WWN app two of the thermostats seem to work properly. The third one appears as a device but does not function with VERA 3. It does not show temperatures, does not respond to mode or temperature change requests through the VERA controller. I have removed and re-installed thermostats and WWN app multiple times but to no avail. The level three thermostats fails to respond or register temperatures. Does anyone have any suggestions for a solution?
