I’ve made a completely new Raspian & MM installation. No other modules installed. the default modules disabled in the config.js.

I Still get no connection. Im running the Home Gatewy V3 in Dev mode. Do I have to change any settings on my router or somewhere else?

Right now I get different error messages. Maybe it helps. I would love to see this module running!

MagicMirror will not quit, but it might be a good idea to check why this happened. Maybe no internet connection?

Thank you for your replay!

When I do so I get a “Connecting to XIAOMI gatway…”

As far as I understand "ENETUNREACH " means Network unreachable. I can successfully ping the Gatway at 192.168.2.107 via VNC & LX Terminal.
Do I have to set up something on my Gateway first?
Any idea what to do?

This is what my error log says:

ERROR! Could not find main module js file for RepositoryForRC

How to figure out the id of the sensor?

Same problem here. I would love to use the occupiedCMD and vacantCMD.
