First of all thank you for this awesome piece of software.
I Love it.
I setup pimatic a month ago and had 2 DHT22 sensors directly attached to the pi through GPIO.
Now i want to add some more and tried to connect then with the Arduino mini.
The problem now:
At least 4 times a day i got extreme values like -3000°C or +200°C.
Also the log is full of Checksum Errors (the cable of the DHT22 is about 20cm long and I had the same Kabel attached to an CAT5.e cabel before, when it was directly connected to the PI).
I tried to set the measuring time to higher values like every 20sec or 1 minute but it didn´t help.
Is it possible to set max value so my statistic graph doesn´t get corrupted?
And how do I get rid of the Checksum Error?
Or is it possible to connect more than one DHT22 sensors on one data GPIO pin on the PI?
thank you for your help
