Since I've moved my nest box and replaced the mains power adapter for a solar panel, I look for ways to reduce the Raspberry Pi power consumption as much as possible.
So far I've found the following tweaks for
#dtparam=audio=on disable_camera_led=1 dtoverlay=disable-bt dtparam=act_led_trigger=none dtparam=act_led_activelow=on
- Disable sound and ALSA daemon
- Disable the camera indicator LED
- Disable Bluetooth
- Disable the on-board indicator LED
Also, I disabled HDMI output by adding
/usr/bin/tvservice -o to
Finally, I've found daemon which I don't need:
sudo apt autoremove triggerhappy
A USB tester is on its way, so hopefully soon I'll able to measure the actual current power consumption.
