Veralite & Trane thermometer

[Chuck]

I noticed the same issue in the recent update. The Trane setpoint, cool setpoint, heat setpoint are all the same. If I set the cool setpoint for 85 it changes the hot setpoint and the setpoint. Yet it all seems to work, the numbers just aren't right.

And you are correct, it was all from the last update that this all changed.

All seemed to go well with this recent update, but it really is easy to miss changes if one had changed the name(s) of the peripheral thermostat units. Here I am talking about the three 'points' that are created in addition to the central thermostat.

The 'setpoint' in this line should be the current setpoint, regardless of heating or cooling. The 'heat' should represent the setpoint that would govern if the system was in the heating mode, and 'cool' should represent the setpoint that would govern if the system was in the cooling mode.  Interestingly, Vera does know the current setpoint. When one looks at the Vera web page to see the thermostat, most everything is there. Vera knows the correct setpoint, but doesn't report it correctly. I don't know if Vera knows the separately reported 'heat' and 'cool' setpoints, but the are recorded in the actual thermostat. Much of this is a change from a prior version of the Vera software. The reporting was accurate then, and I could change the setpoint through the XTension unit. I don't seem to be able to do that now.

One is marked temperature, one is marked humidity, and one is currently an unknown (although I have a suspicion that it is for the currently-uninstalled outdoor thermometer. I am working on that – punched the hole in the wall yesterday and am dealing with conduit, etc.).

I discovered that Vera had re-assigned these last three point (different IDs=different addresses), and I had used those in my XTRemote displays rather than the base units. I fixed that easily, but was alerted to the possibility of address changes with new firmware and automatic reconfiguration of the thermostat units (in Vera).
