Trouble Installing

[bradcarnage]

I am currently trying to install the fork gmc3xx by @alex-vg (issues disabled for that repo), for my GMC300e device into HA.

Not sure where the repo/docker container should be installed. I have the USB port forwarded to my HAOS VM at /dev/ttyUSB0.

I've tried:

• adding the repo thru add-ons (not valid repo)
• installing docker image inside HAOS (no "git" command present, unable to dl+run, no package manager to install git)

Pretty sure the way this project works, is that you run it on the device with the USB port connected, and it reports back via MQTT to HA.

I noticed that gmc3xx has removed MQTT in favor of a native HA endpoint use, but not sure where you'd specify an API endpoint with key, or anything. Not sure if this is how "integrations" or "add-ons" data transfers work with HA (internal docker network with API), so someone please let me know on that.

/rootfs/etc/services.d/gmc320/run#L32 of alex-vg/gmc3xx seems to mean that supervisor is an endpoint which could be reached by a docker container. Little to no docs on how to get this working, so if @alex-vg or someone else could help that would help me wonders :)

That fork was just an experiment. I didn't get it to work.

Usually devices have a fixed baudrate. But in the case of the GMC300-E you can simply configure the baudrate in the device menu to 115200 and use the original addon.
