The device you have is pre-configured to work directly in your car. When working it in a lab environment you may need to supply the AutoPi with a controlled power supply. There is a couple of things you should be aware of, before connecting your device:
Always power your AutoPi from the OBD connector. Don’t use the power inputs on the Raspberry Pi. This makes some of the function on the AutoPi not function correctly and could potentially damage your AutoPi device.
The AutoPi has several commands that can be run from the local terminal. Use help to find them, like “
power.status”. All terminal commands can also be run when logged in via ssh. All you need to do is add them to the autopi command, like “
The AutoPi auto powers down when voltage is below 12.2V. This is to prevent draining the vehicle battery. Power it with 12.5V when in lab.
here is a trigger (sleep timer) on the device, that will initiate if there is no COM to the car. You can see sleep timers by running this command “
power.sleep_timer” and you can disable them by running “
