In my house I have a boiler solution that turns on a lamp whenever there is a problem with the machinery. Example: The fire runs out, the lamp goes on, giving me an indication that the system is down -> I can check it out to find a solution.
I was wondering if there is a device, that can be installed on the power cord for that lamp, as a monitor for the electrical signal?
To be more precise, as the boilers run normally, the device would recieve no electricity, then when the system goes down, the device would recieve electricity and send a notification to me, still turning on the lamp.
Since it depends on coming home to a cold house, I am looking for a solution that notifies me instantly with a push notification or SMS.
Is there a device, suitable for my needs?
