Hallo,
please, can you help me how to make GPIO working in HA at Odroid N2+? I see /dev/gpiochip0 and gpiochip1, but cannot make them working. I have tried some Raspberry GPIO integrations from HACS, but doesn’t work at all. UART at GPIO header works fine, but binary I/O doesn’t.
Any chance you found a solution? I’ve been running an ha supervised install for years on the N2+. I use the GPIO pins to interface with wired alarm sensors. Under standard Debian for ARM you can install the gpiod package for easy access to the GPIO pins. I just did an Debian package upgrade and sadly the HA containers no longer start. As such I’m trying to use Home Assistant OS. I’ve been searching the forum for details on utilize GPIO pins under Home Assistant OS and both sadly and surprisingly, there isn’t much information. The only promising thing I’ve found is here. If you’ve figured anything out, please let me know. Or if someone reading this has some thoughts, please comment. I’d really like to switch over to HA OS, but not having GPIO functionality is problematic.
The response from the HA development team is that GPIO capabilities will not be support within HA OS. In order to switch to HA OS I had to move features off my HA controller. This was the solution I put in place that served my needs.
