Troubleshooting to enable i2c

[eemceebee (Sebastian Scholz)]

Hi, I need to get i2c to be enabled and I followed the instructions from Common Tasks - Operating System - Home Assistant using the Terminal.

But I can not get this to work this way. I need to use the Terminal as I use an SSD drive and can not access this directly due to lack of an adapter

Anyway, according to the docu it should work also directly in the Terminal, but after the reboot I do not have a /dev/i2c-0 or anything similar.

I do see a device when I run lsmod | grep “i2c → i2c 20480 0”, so it is there, but if it does not show up in /dev, I assume it is still not enabled?

Any help ?

So, someone created a nice Addon which is doing the exact thing needed and it works. Not sure what the addon is doing differently, cause in the logs it shows exactly what i did directly in the terminal, but well, it works.
