If I want to run at 1100W during the day and 900W during the night and I want two different Fan speeds:
e.g.
Hi, is there any way to automatically switch performance profiles in Braiins OS at any time? I need him to run at full power at night and only low power during the day. I searched everywhere and didn't find it. Thank you
You need to follow these steps (note that numbers are examples, change them to your proper numbers):
1. Set the tuner power limit to 900 and let the device tune and gets stable
2. SSH to the device and run the command below:
cp /etc/bosminer-autotune.json /etc/tune900.json
3. Now back to the device set the tuner power limit to 1250 and let it tunes and gets stable
4. Again SSH to the device and run the command below:
cp /etc/bosminer-autotune.json /etc/tune1250.json
5. log in to the Braiins OS+ web interface and navigate to System > Schedule Tasks
6. Copy and paste the following command to the text area and save it.
0 9 * * * /etc/init.d/bosminer stop && sed -i 's/psu_power_limit = 1250/psu_power_limit = 900/' /etc/bosminer.toml && cp /etc/tune900.json /etc/bosminer-autotune.json && /etc/init.d/bosminer start
0 21 * * * /etc/init.d/bosminer stop && sed -i 's/psu_power_limit = 900/psu_power_limit = 1250/' /etc/bosminer.toml && cp /etc/tune1250.json /etc/bosminer-autotune.json && /etc/init.d/bosminer start
7. SSH again to the device run the command below:
/etc/init.d/cron restart
8. Set device time zone to your proper time zone
9. The device will work 09:00 to 21:00 with 900w as PSU power limit and 21:00 to 09:00 with 1250w as PSU power limit.
