x708blitz ⚡

This is a fork of x708v2.0 modified to integrate the X708 UPS HAT with RaspiBlitz node

The scripts manage button action, AC power loss detection, battery level, fan speed and ensure a safe shutdown of bitcoind, lnd etc. before cutting off the power

Safe shutdown is triggered by:

• board button
• low battery voltage when AC is lost
• x708off command

Scripts were tested on Geekworm/Suptronics X708 v1.2 board with RaspiBlitz v1.7.2

Contents

• x708.info.py - Fetch AC status & battery voltage. Auto shutdown when AC is lost and battery low
• x708.fan.py - Automatic fan speed control based on custom-set CPU temperature thresholds
• install.sh - Install bash and python scripts, add x708off command
• uninstall.sh - Revert the changes and remove the repository

Setup

On RaspiBlitz patched with HiLivin/raspiblitz:feature-x708-support type:

sudo /home/admin/config.scripts/blitz.ups.sh on x708

You may change the custom values in the scripts:

In file /home/admin/x708blitz/x708.info.py:

MIN_VOLTAGE = 4.0   # (volts) shutdown when voltage drops below this value

In file /home/admin/x708blitz/x708.fan.py:

HIGH_THRESHOLD = 40 # (degrees Celsius) Fan running at high speed at this temperature.
LOW_THRESHOLD = 32  # (degress Celsius) Fan running at low speed  at this temperature.
SLEEP_INTERVAL = 1  # (seconds) How often do we check the core temperature.

Restart to apply changes:

restart

When done you should be able to safely shutdown your RaspiBlitz with x708off command or by holding the board button for 3-7 seconds.

To safely reboot use restart command as usual or hold the button for 1-2 seconds.

Shutting down with the old off won't turn off the X708 board!

The UPS info should be seen on the status screen just right to your node's alias.

To uninstall use this command:

sudo /home/admin/config.scripts/blitz.ups.sh off
