Very interested in this discussion…
We have a steam system with boiler. When the water level gets too low, a low water cutoff kicks in (pictured below) and the boiler stops boiling water until I manually refill the system. During the winter this has been happening every 3-5 days! And it always seems to happen at 3am. (Why do these things ALWAYS happen in the middle of the night??) We’ll wake up to a freezing house and I’ll have to scurry down to the basement to refill the system.
I’ll admit that I could make refilling the system part of my nightly ritual, but that’s no fun and we have busy lives.
Right now I’m using the “It’s Too Cold” Smartapp to alert me when the temperature drops below my thermostat’s threshold. This works during waking hours, but not really in the middle of the night. I tried to set up an IFTTT recipe to call my phone when the temperature drops to a certain level, but it has never worked. Not sure why. Regardless, these alerts only work when the temperature is already way too cold. I’d love a warning like the Ecobee gives so we don’t have to freeze our butts off.
The low water cutoff is, as I understand it, just a simple switch. When the water is low, it shuts down the boiler. I’d love to hack something together, attaching this to a z-wave switch or something so I get an alert when the cutoff has been activated. Perhaps using a door sensor and putting it on the circuit between the cutoff and the boiler? As someone said above, it’s not for the faint of heart. I’d have to get an electrician or HVAC person.
