For the stock firmware, you can configure the LEDs to act on certain events. Blink blue with network traffic:
uci set system.@led[0].name=wwan-link
uci set system.@led[0].trigger=netdev
uci set system.@led[0].dev=wlan0
uci set system.@led[0].mode='link tx rx'
uci commit system
/etc/init.d/led restart
The relay is tied to the red LED, so setting the LED to default ON will make the relay ON after bootup:
uci set system.@led[1].default=1
uci commit system
/etc/init.d/led restart
