I was hoping to have 1 device that could be a home router as well as monitor voltage from a battery backup source. So I'm looking for a lower cost router that has Wi-Fi and has voltage monitoring. So far I've found the hAP lite, ac2, ac3, ax2 and L009 do not have voltage monitor unless I missed it. The other 2 options are hAP AC or Audience. Do they have voltage monitor? If not I will probably have to use 2 devices. The lowest cost Mikrotik I know of with voltage monitor is the hEX.

Thanks jaclaz! I didn't think about the mAP. Yes, it will work as a monitor. Ordering a hAP AC to test.
