Just a quick note on those DHT11/DHT22 sensors

Thanks for the information. It might help to explain what I am thinking of doing...I might be wildly off with my plans...

At home, we have a smart thermostat. It is controllable by Alexa and remotely from our phones. It is supposed to have geofencing but doesn't handle having two people connected. Sometimes, I will go out, and the heating will turn right down, which would be fine if my partner were not still at home wanting the heating!

I've also noticed that the thermostat can read 18 degrees in the summer, and we feel nice and warm. Yet in the winter, the thermostat can read 20 degrees and we feel chilly. So, something more than temperature is at play. I am guessing at humidity.

My plan iswas to fit a DHT22 connected to a Raspberry Pi Zero in an enclosure outside. Then, to have a more powerful Raspberry Pi inside with a DHT11 connected. That would allow me to measure the indoor and outdoor temperature and humidity and set the heating accordingly. Some experimentation would be needed to set it up correctly, but that would be a software issue once the hardware is set up.

It would be nice to have the heating keeping the perceived temperature constant throughout the year rather than the absolute temperature.

I only have to worry about switching the central heating boiler on and off - here in the UK we don't have air conditioning. Only me office has that luxury.
