Can i run Matter server in Docker container in eWeLink CUBE ?
I’m not entirely sure what you mean by that. There is no need to install an additional Matter server on eWeLink CUBE.
CUBE OS already includes built-in Matter Bridge and Matter Hub components. This means that whether you want to bridge your devices into a Matter network, or connect and manage other Matter devices that are already part of a Matter network, no extra installation is required.
Everything needed for Matter functionality is already provided out of the box by CUBE OS.
The matter server in eWelink CUBE has limited device support. I need to run the matter server in Docker for Home Assistant.
