Shelly 3EM with 3 terminals / no WATT output in App....

[Steve2]

Hi, I have asked my electrician to connect a Shelly 3EM with 3 terminals. But now get no measurement results in the app, off for volts. See photo... Are the taps the right way around? Thank you 😃

Thank you for the revealing photo of your installation! After some minutes laughing, I‘m ready to write a comment:

The electrician has mounted the current clamps at the open ends of the three copper busbars, where absolutely no current is flowing. Correct installation would be to put clamps between the switch and the wire clamps (black, grey and brown wire).

Thanks for your feedback thgoebel, 🤔 I paid him more  then 100€/hour for the installation.

So all clamps need to move a bit to the left then, right?

Right!
