How to monitor propane grill?

Mea culpa. I left the grill on. For several days.

What kind of sensor would work to detect that the grill stays hot too long? It's in a covered summer kitchen (lanai) so it's outside but not really exposed.

I also need to put a monitor on the underground propane tank. There was a thread about that on the boards somewhere. Need to find it.

I'd weigh the tank using a load cell and use a thermocouple for sensing the heat. An Arduino could get the data back to Indigo.

It's a 500gal underground tank. I did say it ran for several days before it noticed it was left on....

The thermocouple would work, I guess. I was hoping for possibly a Z-wave sensor so I don't need to add lots of new devices to maintain.

You could go the cheap route and put in an inexpensive temperature monitor under the grill, even from a foot away it should be substantially warmer than the ambient temperature.

Yeah, that was sort of what I was thinking. Any specific units you think would work? I don't currently have any temperature sensors at all, except for the Ecobee sensors.

What about an RFXCOM with a temp monitor close by?

Pretty pricey just to get one temp sensor. I could put a Z-wave multi-sensor under the grill for a lot less. But I don't need motion, light, humidity, etc.

Those are probably the least expensive of the prebuilt types.

If you are into to it. Esp8622+varistor. $10 total
there a several plugins that can be used to get the info to indigo. Mqtt and arduino plugin.

But not if you already HAVE the RFX watching the refrigerator and freezer temperatures as I do... plus half a dozen other temp sensors scattered around the house, although those aren't anywhere near as critical as knowing before several hundred dollars of frozen food is about to thaw...
