I’m building a 12v trigger relay for an external subwoofer amp. It will be housed in a 4x4 steel electrical box.
Trying to see if there is a surface temperature sensor that I can stick to it that can monitor the temperature and if it goes over a certain level, that can warn me. Ideally integrated with my Smartthings ecosystem.
More of a “safe vs sorry” sort of thing, probably overkill.
