🐞 [Bug]: Power Metrics Telemetry not reported correctly for INA219BID

[eric-becker]

Firmware Version

2.3.8

What did you do?

On two separate nodes, I installed a RAK16000 DC Current Module (INA219BID) on the IO slot of a RAK19007 board with RAK4631 Core and toggled on Telemetry -> Power Options -> Enabled. The sensor has vin+ connected to the positive lead from a RAK Unify solar panel and vin- connected to the positive lead going to the solar port. Both ground leads are connected to GND on the module.

Expected Behavior

DC Current values to be displayed in the Apple client similar to the Android client.

Current Behavior

The client receives standard telemetry alternating with incorrect zero or null values resulting in 0% battery sometimes displayed for the node as well as a sawtooth pattern for the graphs.
