@sdetweil you could make the MM start script fix the config entry
here is a little script you can use to modify the config when MM is started
#!/bin/bash
#
# get the active adapter name
#
adapter=$(ip link show | grep mtu | grep -v lo | grep up | grep -v -i docker | grep "state UP" | awk -F: '{print $2}' | awk '{print $1}')
#
# use the adapter name to get the assigned IP address
#
address=$(ifconfig $adapter | grep "inet " | awk '{print $2}')
#
# use for debugging
# echo address for adapter $adapter is $address
#
# use the address in sed replace of the line that starts with text:"http:/
# -i means update file in place
# file at the end needs the path (~/MagicMirror/config/config.js
#
sed -i "/text:\"http:/ c \ \"text\"\:\"http://$address:8080/modules/remoteControl.html\"," config.js
u could add this to the mm.sh used to start MM on boot,etc…
I don’t know the end of the remotecontrol link… so that has to be fixed too…
just have something in config.js when this runs , this should run before npm start
this works for ipV4… haven’t tried with ipV6 network
the grep "inet " filters out the v6 address “inet6” would select just that address
docs says
Because IPv6 addresses contain colons, they cannot be directly used in URLs because the colons would conflict with both the protocol declaration (http:// or https://) and port numbers. Therefore, when a literal IPv6 address is used, it is encased in a bracket, like http://[2001:db8::1]:80.
so that would be a tiny change to the sed string
