Shelly Plus UNI - ADC not working

Hardware
1

I have just purchased 3 Shelly Plus Uni devices, and as much as I hate these devices, the ADC on it will not work. I am also unable to update the firmware because as usual its a cloud dependent device and manual firmware downloads are not offered.

Right now, I have gone into the device web settings, added a peripheral for “Voltage Meter” and wired my sensor (0 - 5v output) to the Analog wire of my UNI.

If I measure with a meter between ground and the DATA of my sensor, I am getting 1.3v however in the UNI, it still just sits at 0.3v

Any ideas?

You need common ground between the sensor and Shelly as well.
Feel free to post your wiring.

Shellys are not cloud dependent devices, you can get everything from the local web server it creates and disconnect it from cloud.

Be aware, Shelly Uni and Uni Plus have completely different wiring scheme for inputs and different max supply voltage.
