enhance flood and freeze sensor for heat

It’d be cool if we could use the floor and freeze sensor to detect high heats as well.

This would be useful in basement utility rooms where things like boilers are installed. This would make the “floor and freeze” senson more of a “climate” sensor.

It should be able to alert us if temperature rises above a set thresholds, or drops below a certain threshold.

floor = flood (typo in original post)
