Hello radxa community,
my quad sata hat is running well on a Pi 4b with DietPi.
I noticed in fan.py that an optional w1-sensor is queried and the max of that value and the cpu temperature is used to control the fans and in misc.py a w1-interface is activated.
Would it work and cause no conflict if I solder a DS18B20 data wire (DQ) to GPIO 4 (pin 7, bcm 4)?
I like to take better control over HHD temperature in case of low cpu usage and spun down HDDs.
The only working way I found to read HHD temperature is by
smartctl -a /dev/sda | grep Tempe | cut -d" " -f 2,37
But this spins up HDDs that are asleep over night to preserve their life span.
