I know there is OpenWISP. However OpenWISP is just for configuring the OpenWRT APs. Omada Controller provides valuable information like what client is associated with which AP, connection time and a lot more.
Example:
I am also looking for a central controller for OpenWrt.
I have several routers / APs distributed around the house and would like to manage things like WLAN SSIDs + passwords or create VLANs via a central point.
An overview of connected WLAN devices with IP / MAC and speeds would also be quite good.
Displaying current software versions and pushing new images would also be cool.
I have already looked at OpenWISP, but it is far too complicated for "simple use".
It's a great project, but somehow not for me.
