NOTE: There's a bug in the fan controller; if you enable automatic fan control it will forget any previously-set target despite it appearing to be set correctly (i.e. `cat /sys/class/hwmon/hwmon5/fan1_target` will display the correct value).

# Set battery charge rate
Set the charge rate: `echo {rate} > /sys/class/hwmon/hwmon5/maximum_battery_charge_rate` where `{rate}` is the charge rate in mA, between 250 and 2500 mA.
That file is write only, so changes cannot be directly observed.
# Set battery charge mode
There exists a binary which may or may not be executable (depending on which SteamOS version) which can be used to set this and other things. [More details in the issue](https://github.com/NGnius/PowerTools/issues/50).
Refer to [util.rs](https://github.com/NGnius/PowerTools/blob/main/backend/src/settings/steam_deck/util.rs) for how the firmware interface works.
