I wasn't thinking monitoring GFCI only but if that is a concern then yes.
I have a plant I do work for that has steam boiler that provides steam for processing as well as some heating. Several years ago after boiler shut down a couple different times on very cold nights and caused other issues when things froze up in the plant we put in Sensaphone system - landline phone connected. We have a temperature sensor in the room that is pretty much entirely heated by the boiler as well as a relay contact tied into boiler controls that opens a contact anytime the boiler control power is lost or if the boiler goes into alarm status. By default the unit also makes calls if AC power to the unit itself is lost, so even though the general use receptacle circuit it is on is not too likely to trip anything, it still goes out if utility power is lost. If there were to be other critical items to monitor we could easily tie a monitoring contact or even temp sensor directly to another input zone and monitor that item.
Certain plant employees are on the auto dialer list and it goes through each number until someone enters an acknowledgement code. one potential drawback is I believe it only goes through the number list 100 times then ceases dialing on that particular alarm instance. But if another zone or alarm condition would happen it will go through again.
Majority of alarm calls have been either boiler ignition failure or maybe low level conditions because of feed pump failure of some sort. Employee gets the alarm call goes to plant resets the locked out boiler control and it either starts up again or fails again and they possibly end up calling me if they don't know how to fix the problem. I've been called at 2 AM when it there is problems he can't fix, especially on cold nights. But also may still get called in middle of night in summer if they are planning to need boiler for processing the next day as a lot of products they make need steam for part of processing. I'm far enough away they don't want to have me come in and reset it and nothing fails again.
