Temperature values "Zuluft / Fortluft" #5

How did you get the temperatures of "Zuluft" and "Fortluft"?

chrishrb commented 2 years ago

I installed seperate sensors, read them over a small c script and connected it to home assistant. So it has nothing to do with the hoval system because it doesn't provide this two values.

If you are interested which sensors I used and how I integrated them into this system, let me know so I can write you a small tutorial.

ok, I almost thought so. Yes of course I'm interested in how you did it. A few sentences of explanation are enough for me. If I would do it, I would probably just stick some zigbee sensors into the device.

I used a pair of DS18B20 sensors [1], a ESP8266 microcontroller [2] and some resistors, cabels etc. I don't have the exact layout of the board here but I'm sure you will find the necessary layouts on the internet. I soldered the microcontroller on the board an programmed [3] it to transfer the values of the sensors to a mqtt broker where I can read it from my home assistant setup.

Thanks @chrishrb ! Can you also tell me where you placed the sensors? Maybe some pictures? I think i will also add those but maybe connect them directly to the raspberry pi.
