that’s why I got my mikrotik hap ax2 in the first place
it’s does have a low voltage disconnect cause it’s the BMS job to protect the battery and circuit
get a mikrotik they are good for the price and setup recursive routing so what I’m using right now is 2 wans or you could use 1 wan and 1 4g or plug a phone on the usb port and turn on usb tethering so basically recursive routing checks if a host is up on a line say isp 1 pings to see if 1.1.1.1 is up if not switch to isp 2 isp 1 is my own line and isp 2 is my apartment’s shared internet connection that has unstable speeds but for failover, it’s better than nothing
is it worth getting that secondary ap the ac mesh or should i just downgrade the lr to the plus
minght also get the lr and fidle around the the power settings
