Hi, I have the Pironman v2 case. When using the regular raspberry pi OS, the OLED display worked correctly. I have now switched to home assistant OS. I have followed the config instructions and also installed the add-on. In have disabled protection mode. However the display just says “Power off”. Here are the logs: ## s6-rc: info: service s6rc-oneshot-runner: starting s6-rc: info: service s6rc-oneshot-runner successfully started s6-rc: info: service base-addon-banner: starting ## Add-on: Pironman Pironman support ## Add-on version: 1.0.7 You are running the latest version of this add-on.

1、Please provide a video of the problem to us, so that we can analyze and solve the problem. 2、You can try to use two power supplies to power the pironman and raspberry pi separately to see if they work properly. 3、You only connect a power supply to the pironman motherboard, and start the pironman work, and then use a multimeter to measure the output voltage of the GPIO 5V, GND pin, to see how much the voltage, the normal voltage is about 5V. Please provide measurement data or pictures of measurement data. ---

I tried using a 100w laptop power supply and everything now works correctly. What is the minimum power supply you would suggest I need? ---

It is recommended that you use a 5V 3A power supply for power supply, do not use a power supply with much working voltage. It is easy to damage the motherboard.
