Yesterday I connectect every DHT22 sensor to HA.
This morning I checked I chart of the temperature and unfortunately I found that sometime the readed temperature is wrong.
Here some examples:
I have a DHT22 connected to a Sonoff. The Sonoff sends temperature and humidity data from the DHT22 to homeassistant via MQTT. I have not seen the apparent wild variability that you are seeing. How do you have the DHT22 connected and how is the data getting to homeassistant in your configuration?
Thanks for your answers.
I think I found the problem.
I don’t want to use wifi sensor so I wired all my rooms.
As you can Imagine there are sensors near PI and sensors far…
Thinking about that I used a ethernet cable in order to reduce the noise.
I discovered the near sensors work properly, but reading from far sensors sometimes I receive this “strange” values.
What’s the best way to solve the problem? Is there any way to discard them?
