When I update Librenms from 25 to 26.1 by daily.sh there is a problem with Mikrotik Router OS Voltage sensor, tested on many Mikrotiks v6.49, v7.2, v7.18, v7.19, v7.20, and the same, Voltage is wrong. Rediscovery not help.
In most of value Voltage0 is wrongly divided by 10, there is also a problem with SFP voltage.

1. Before update all was fine, how can i fix that ?
2. Can I change divider for specific sensor on my own ?

The divisor of 10 has been in for a long time, without a discovery and walk debug output as per the template when creating this, we can’t do much.

Probably I don’t update long time, but after update I noticed a problem.

RouterOS v6.49 ( “voltage” sensor is correct but “Voltage 0”sensor is wrong, divided by 10)
