[DRIVER] APC AP9319 - SNMP Temperature, Humidity and input relay

krynos42 · December 21, 2025, 8:05pm

Support for APC devices for Temperature, humidity and input relay.
Most APC Powernet devices should work.

Driver to follow.

I have an AP9631 with a temperature/humidity sensor that should arrive in a couple weeks... If you want I am happy to provide some feedback on this as it stands now and such (and more once I actually get the sensor).

Do you plan on adding more to the driver, such as reading the current input/output/battery levels, etc? Be pretty interested in getting that information into Hubitat.

FYI there are already several community drivers for the AP9631. I’ve used a couple different ones — they work great. Doubt they’d support the AP9319, but if you’re looking to get battery levels and a bunch of other controls and data into Hubitat, that’s very doable!

I did it for a device with potential for 2 temperatures and humidity sensors (I just support 1) and 4 input relay.
Adding support for a UPS would probably be be easy since it's basic SNMP requests using the APC PowerNet MIB. Maybe a separate driver for UPS functionality could be a good idea.

Sorry. I mentioned it because I saw the APC AP9319 thread I immediately thought how close that was to mine... I did not know there were others out there specifically for the AP9631 (as @mluck mentioned) simply because I never even thought to look for them. Doh. Blind spot I guess. No sense in having you change your driver for things that already exist.

my driver works for the 9630 and 9631. never tried the 9319 (too expensive) you can get 9631s on ebay for around 20 dollars.

That is how I have mine. Card is cheap... sensor probe is like 2+ times more. Of course the AP9631 is discontinued (and the firmware they offer is fairly old).

kahn-hubitat · December 24, 2025, 1:58am

you can update the 9631 firmware I have updated all mine

Same here.

The network card is as updated as it gets (7.2.2 which released in August) which is not bad. I was more meaning the bootmon, mine shows as 1.0.9 (which is from 2019). The APC's firmware is the latest available for it (15.0). The problem with a 11 year old UPS (all the batteries have been replaced recently though, when I got it and the external power pack, so it works fine). Fun times there.

Anyways, sidetracking from @krynos42's main topic here! Sorry for the derailment.
