Are all the access point on the same network? Are they all the same model? If so, what model? Last, do AP need to be full power cycled or are you looking for remote reset access?
If you can ping them all from the computer you wish to monitor from, then I would suggest something like Pingplotter and set up some alarms for the different IP for the AP's IPs. See here for instructions. This may be problematic if you use WPS or MESH to connect your AP since the LAN IP won't be accessible. In that case, try a WOL sniffer then can ARP to each AP's specific MAC address.
If the routers were the same or similar model, some manufactures will offer cloud access to each AP via different methods. This requires each AP to have internet access though. Other models have SNMP or SSH or wIPS that you could use in different ways to either monitor or control(force reset).
