Mimosa Devices Overdrawing

[thewisp]

Hello All,
Thanks for your time.

We've got dozens of Netonix and Mimosa devices throughout the network. Today I discovered some odd power consumption from two Mimosa devices on the same site.

I've power cycled both, without any change. Anyone else run into this before?

Oddly enough, I just had a tech swap ports 2 and 9. The issue did not follow the port. Nor did it follow the device.

The Mikrotik device in Ether2 is pulling it's expected 40W~.
The Mimosa B5c moved from Ether2 to Ether9 is pulling it's expected 12W~. Not the 80W~ it was pulling when plugged into Ether2.

However, Ether3 still reports an overdraw of watts.

Still no idea what to think of this.

looks like a blown current sensor, pretty easy fix if oyu know how to solder

I concur... it is a blown current sensor. Usual culprit is excess current from insufficient grounding (bonding).
