Is there an easy way to use the serial port on a RB532 to monitor AC voltage status?
Some of our sites are at locations with iffy AC power. Things like having a window air conditioner on the same circuit that overloads things when it gets too hot out, etc.
We're working around these, slowly, but in the mean time, we've been using battery chargers, marine batteries, and inverters to power things. This works great, except for the fact that we don't have any way to tell if AC power is offline (and get out there to reset the breaker).
Are there any devices, either SNMP enabled, or serial port accessible, that would let us monitor AC voltage & raise an alarm when the circuit goes offline?
The other option I was thinking of is using a small APC UPS to monitor things via the UPS monitoring support.
