How likely is it that SNMP integration can be done for this device? I just bought 2 units; not really into home automation and I would like to have the units monitored by PRTG or similar, not to mention that this would make the device viable for a very wide range of applications and scenarios out of the box.
AFAIK, the device doesn’t expose any servers (at least with the stock firmware). Your best bet might be a minimal snmpd that exposes custom OIDs, and populates the values from the AG REST API. The Net-SNMPd “extend” operator is probably insecure, but seems like it would work: https://www.puppeteers.net/blog/extending-snmpd-with-custom-scripts/ , https://geekpeek.net/extend-snmp-run-bash-scripts-via-snmp/
Have “extend” invoke any script or wget/curl/shell script that outputs only the requested value.
If you’re mostly interested in PRTG itself, not other SNMP agents, REST API monitoring: check availability and up to 50 values with just one sensor might be able to poll the REST API natively.
