Is there a way to monitor the input supply voltage of a TRB255 via an SNMP query? We are using the TRB255 to backhaul off-grid weather and various other sensors and would like to monitor the voltage state without adding more equipment. I see we can jumper the supply voltage over to the Analog input but is there an SNMP OID I can monitor to log this value? Attached is an example of how we monitor this using SNMP on our Sierra Wireless RV50 cell modems.
Yes, it is possible to read the voltage value of the analog input on TRB255.
Analog input voltage range: 0-30 V.
