insteonaus

I just upgraded my ISY994i to v5.0.16C and my Insteon thermostat 2441ZTH is no longer working. The temperature field is blank. I believe the other values are still accurate, but I have not tested thoroughly. The "Setpoint Up" and "Setpoint Down" buttons throw errors. I deleted the thermostat and re-linked it, but that did not solve the problem. Any suggestions on how to resolve this issue would be greatly appreciated. Below is the screen shot and the result of a query. EDIT: I logged back in hours later and now the temperature is showing up. I don't know what changed, but I tried manually querying the device earlier and that did not make the temperature appear.
