Hi there - long time lurker, first time poster.
I’ve looked around and haven’t found what I’m looking for, hence the question here.
I have two power supplies coming to my house: the regular electricity and a third-party generator (due to the freq electricity cuts in my country). In the power box, we have installed two lights, one red and one green, so we can tell by looking at them which source is coming through. Regular electricity gives us 30Amp total and is metered, generator gives us 10Amp total and is unmetered. So it’s important for us to know which power is coming through.
I’d like to add a sensor to my ST that would let me know somehow which power source is working now. Either a light sensor I can stick facing the box that would recognize the difference between red and green, either something we can install in the power box that would know if/which power it’s being fed.
Just to make things worse, I have an ST2 hub (US ZWave), but I live in a country with 220V power supply. Battery-powered sensors are obviously a better solution, but I’ve come across stuff that works on 220V with US Zwave.
