on my GrovePi board i’am using a DHT Pro sensor, the high accuracy I2C barometric sensor, a temperature sensor and a moisture sensor on analog ports, an I2C relay board and some digital input/ouput modules.
I read in the forum a few threads that the sensor values are messing up sometimes when using DHT and analog sensors together.
I have exactly the same problems. When i add a time.sleep after each read of a sensor value it is getting better, but at least after about 5 minutes, the analog temperature value is not updated anymore and returns from now on always the same value.
I have seen the thread with the new firmware release and read that the new firmware should solve the problems.
So I installed the new firmware 1.3.0 to test if things are getting better.
But now ,with the new firmware the DHT sensor returns only 0.0 values for temperature and humidity.
But at least it looks like, that the mess up on analog ports is gone, so values from analog sensors
seems to be fine over a long time.
