I have a gas water heater that will occasionally get the pilot light blown out by West Texas wind gusts. I have my Netatmo alerting me through Hubitat when I receive wind gusts of 25+ mph but that doesn't always mean that the pilot light has blown out. For the record the vent plumbing is all correct. Temperature sensors don't seem to be able to tell me they seem to give me false positives when the pilot light is still lit. So it got me to thinking. If I could find a device that would read voltage, I could wire it into the thermopile and get a notification that would tell me 100% if the pilot light is out. Any ideas?
Thermopile voltage would be from 0 to 750 millivolts.
