Does anyone make a “Wifi Plug with a Temp sensor”, or know of a diy, I can build myself. I know about using a “Sonoff Basic”, but, it won’t work for this project. oh, and it needs to be a “single US socket”.
You realize any US Plug with a temperature sensor ( I assume that is what Temp means) would be influenced by any heat in the Plug due to the electrical load drawn through it.
The temp sensor could be on a wire. But it will give a reading at floor level which is generally not the same as higher up.
Actually it is for an apartment Attic fan. Can Anyone recommend a Plug, that is really, really, really, easy to modify.
Have a look at Shelly sensors.
DIY Easy to built into the fan:
External sensors
(will need aditional Shelly actuator that controls the fan):
