I have a shelly uni connect to a tank level sensor. When I look at the shelly uni directly at its embedded web server it shows the ADC at 2 decimal places of accuracy.
But using the core shelly integration the sensor report only 1 decimal place of accuracy.
Why?
I’ve ordered all the hardware to do exactly the same and I agree I would be nice to have 2 decimals for this specific purpose.
Did you find any solution ?
