Hi, I have DSC Power G PG9905 with wired probe and I installed it in my sauna. The rage of the Power G device -22F- +158F . I installed the prob to the height where the temp is never gets above 130F at max heater.
Now for a day my alarm.com page and the web page show that I have 124 F there, while it is 73.5 inside.
I ran a test of the PowerG device from my panel and the device has strong connection and shows correct 73.8F, but it is stuck to 124 F at my alarm.com app and the web. I think the problem with temp probes came back with new firmware.
There is an issue we noticed with the IQ Panel 4 with regard to the PG9905 where in Alarm.com the temperature never changes unless the device exceeds a threshold or returns to within the thresholds. It only reports the one change to Alarm.com (or ADC only processes the one). The same issue is likely occurring in your case with the IQ Panel 2+.
Alarm.com released some commercial specific monitoring package options for PG9905 temp monitoring not available to normal residential Alarm.com accounts. We reported this PG9905 behavior to ADC and Qolsys. Qolsys was working with ADC to find out if this was an undocumented behavior that is now expected without commercial specific temp monitoring features (which I would say is a terrible decision if true) or if it is a bug with the implementation. I haven’t heard confirmation one way or the other, so I just reached out again to our contacts about that.
