Dear all
This has been driving me nuts and I’ve searched everywhere without any luck.
I’ve installed the HA OS on a Raspberry Pi 3+ using the installer on the HA website and I can access HA and it looks great.
I want to create a Server Room Temperature and Humidity monitor using a DHT22.
I’ve wired the DHT22 directly onto the Pi 3+ and it works using basic code found on different websites.
I wanted to find a platform that could send me emails if the temperature/ humidity is too low/high and I thought HA would be ideal.
My main sticking point is the installation of the libgpiod2 library. I can’t find anywhere to run the sudo apt install libgpiod2 command mentioned here on the HA website DHT Sensor - Home Assistant
I can access the configuration.yaml file to make the changes listed on this official HA page but not install the library.
Is any of this possible using the method I have used so far or am I wasting my time?
Can a Raspberry Pi with a DHT22 directly attached send me email alerts using Home Assistant?
If anyone has any suggestions that would great, or any advice on using a different platform or anything at all!
Thank you
