INA219 0x42: Couldn't read values: Error: CNVR is not set, not ready

[jobe451]

I run ioBroker on Rapi 4 with a Waveshare USP HAT.
When I try to fetch the power readings with ioBroker.i2c, I get this error:
"INA219 0x42: Couldn't read values: Error: CNVR is not set, not ready"

Things that work:

• I can properly read the power consumption / battery level with the waveshare python script from https://www.waveshare.com/wiki/UPS_HAT via console.
• ioBroker.i2c properly finds the device when searching on i2c address 0x42

These are the settings I use:

I compared a bit the python code against with the code here and got it working. The trick is to disable the "Einzelmessung"/"singleShot" tick.

I don't understand the difference between the two modes. I guess if somebody would need "singleShot" that there would need to be some wait time be added between writing the configuration and reading the values. This I assume because of the CNVR description at page 23 of https://www.ti.com/lit/ds/symlink/ina219.pdf.

Now I get similar values in ioBroker compared to the manufacturers python script:

The battery percentage that are seen in the output from the shell-script are calculated based on the voltage:
(bus_voltage - 6)/2.4*100 (this might be not universal)
