I use some battery on my tower tu supply electricity power to RB. I need to monitor the battery voltage remotely by ethernet connection.
Pls advise what device should I use. Or any idea how to monitor from winbox?
Are you using PoE to supply power to the router? If you do, then I would recommend a RB433ah, or another similar device with voltage monitor. There is a script in the wiki that emails the hourly voltages once a day, and sends alert emails when the voltage drops below a certain point. http://wiki.mikrotik.com/wiki/Monitor_i ... B333/433AH
