Here's another idea. I don't know anything about Nagios, but I'm running this screwy setup where I made up my own thermostat(s), and in the living room, the one has a small OLED display for set point, current temp, and also outside temp and wind chill that gets sent from my weather station's weewx via MQTT. I'm sending a few observations along with the current time from weewx. The receivers track to make sure the values are changing, and I get a text message when things are askew. In any case, if Nagios can listen to MQTT messages, this is pretty easy to set up. Chris
