Hi, I would like to measure the voltage using rb433ah, to know when system is going on battery.
When there is real voltage 14,5V mikrotik shows 12,5V.
When I put it just on battery voltage real is 13,5V , mikrotik shows 11,5V.
So it seems that it measures the voltage real -2V.
Is that like I suppose or it measures voltage everytime different(not precise?).
