Hi, I’m hoping to monitor the temperature in a garage freezer, such that I can get a notification from Alarm.com on my phone if the compressor ever fails and the temperature exceeds some programmed threshold. I have an Qolsys IQ 2 Plus panel. It seemed that the PG9905 temperature sensor might be the best choice for this application, especially when used with the optional external temperature probe.
However, I’ve read the PG9905 is limited in that there is no way to receive high/low temperature notifications from Alarm.com when using this device. Is this accurate and current? If this is the case, is there a less-obvious benefit to using this device that I am missing - would there be some local notification at the panel, instead?
Another approach seems to be using a ADC-S2000-T-RA remote temperature sensor for this purpose, but then I’d be forced to place it directly in the freezer (i.e. no external temp probe), which I imagine could exceed recommended environment ratings at worst, and wreak havoc on battery life at best. I haven’t found any recommended operating temperature for these RTSes; does anyone know what they are? Does anyone have experience in using these for freezer temp monitoring applications…?
