Python library for the Fan SHIM for Raspberry Pi
Hey guys, the preempt feature doesn't seem to work with 32bit userland 64bit kernel on raspberry pi os / rpi 4b. when i use with the preempt, everything is ok...
If someone takes a fresh Pi 4 and installs a fan shim and nothing else, it is possible it will never spin at all. Any older revision of the Pi...
It looks like in many (all?) cases we can just attempt to read `/sys/class/thermal/thermal_zone0/temp` and `/sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq` to get the current CPU temperature and CPU scaling frequency- avoiding the psutil dependency....
Added basic fan status logging for use with external metrics collectors. Example for Telegraf: ``` [[inputs.file]] files = ["/var/log/fanshim_status"] name_override = "fanshim_status" data_format = "value" data_type = "integer" ```
Fixing the manual mode. After switching modes by long press, once a short press on button is detected the fan will switch and stay in new mode rather than reverting...
Currently the setup script generates a unit file with the settings (on/off temperature etc) hardcoded into the command line. This has a few problems: * The settings are difficult to...
My umask for user pi is 077 because I don't like everything to be world-readable by default. I installed the fanshim library and daemon and it works well. Later, I...
Following up on https://github.com/pimoroni/fanshim-python/issues/19, I made a quick C++ code for the fanshim (no button yet). Anyone interested in review the code for bugs, etc? Note that it's very experimental/rough...
When automatic.py first loads, the python start-up causes a CPU spike large enough to trigger the fan preempt mode. This causes the fan to spin for a few ms at...
