HassOS I2C Configurator
This project enables the Raspberry Pi I2C bus from an addon. You can connect an SDCard and up to two hard disks or USB drives, which are detected as sda or sdb, and they will all have I2C enabled when you click start.
This project is a part of my HassOS Configurator project. The goal of this add-on, similar to root apps on Android, is to make a mole-hill out of a mountain.
Click “HassOS I2C Configurator”, then install.
There is no configuration. This will enable I2C on mmcblk0p1, sda1, and sdb1
Hit the start button and observe the logs. When complete, reboot. This will place the files into the system. After this, reboot again to activate I2C. This takes two reboots. You may uninstall the Add-On when complete.
It didn’t work
Did you reboot the device twice or did you restart Home Assistant? You have to reboot twice.
It still didn’t work
Are you sure you rebooted? Maybe you restarted the supervisor instead? You have to reboot twice
it still didn’t work and I’m sure I rebooted twice
Ok, then perform a hard reboot and run it again, then post your logs.
