INA219 measurement problem above 16V

Hello Guys,

I have a problem with the voltage measurement in Node-RED with the INA219 flow
(node-red-contrib-easybotics-ina219-sensor (node) - Node-RED)

The voltage changes when it reaches approx. 16V and goes negative.
How can I solve the problem? Do you have a suggestion for me?

I would look forward to an answer, thank you very much and greetings.

Probably the same issue that was reported (and unresolved) over 3y ago: Wrong voltage calculation · Issue #9 · easybotics/node-red-contrib-easybotics-ina219 · GitHub

You could attempt a DIY solution:

Include this library in a function node setup tab and write code for reading your sensor (the README has code examples)
