Hi,

We have in our company 3 silos that store glue and the users have to go close to them to check the percentage occupied.
Is it possible to put a Shelly 1 PM (or other) and get the value of the display? known that 0 is 0% and 20mA is 100%.

Thanks!

Maybe, shelly uni can be used.

Sorry, i can't help more.

But perhaps DIYROLLY has an idea?

Hi!

You can use a Konverter 0-20mA to DC Voltage something like this:

You can also use a Resistor 1% directly on UNI
