I spend hours looking for a wired temperature sensor for the HA. I can find many wireless options, and also wired DIY options, but none of the DIY are really easy enough to setup for someone like myself that lacks the experience to build devices from scratch. I have read many posts on this forum as well, but none of the suggested solution I could find is compatible to what I need and can do myself.
Anyone out there that can advice me on a wired temperature sensor that can be easily connected up with HA without any or very little DIY?
Thanks for the quick response! This solution will involve soldering the DS18b20 on to the NodeMCU correct? And than connect the NodeMCU to an Ethernet cable? And lastly I can easily read the temperature from the NodeMCU into HA?
Last thing I am wondering, has anyone found a way to nicely integrate the sensor in a room. It’s going to be around eye head in a room to get the correct temp. I guess it has to stick out from the wall and can’t be hidden behind a roster as this will impact the measurements.
Putting it hidden behind something or in corners will not work for my situation as it’s going to control underfloor heating and AC at same time to get room temp correct.
Only if there is a “correct” temp. Without (strong?) ventilation it’s probably just not the same temperature everywhere in the room
As a rule of thumb don’t place the sensor on the floor or ceiling as they are the mostly the low and high end regarding the temperature. You obviously also want to avoid to have (close) to a heater - as you have underfloor heating that’s probably not a problem at all as it’s quite “low” temperature compared to “traditional” heaters.
For a start you could also just hook up 3 or 4 temperatures (on one esp) to place them on 3/4 four spots and compare them (watch them couple of days to see how the heating cycles influence them and if there is a big difference between them).
