Issue with Shelly Pro 4PM


Recommended Posts

Hi, my electrician did this wiring on two Shelly Pro 4PM devices. He has no experience with Shelly from before, but he says the wiring seemed straigth forward, and assumes they should work just fine. 

They don't. The units power up, but when trying to open the circuits, nothing happens. I have verified that there is power and correct V in, but not out. 
Can you help me out?

What are all the blue wires connected to O1-O4 and the brown wires to S1-S4?A sketch of the wiring would be helpful

L&N from the relays which provide power to the building (the two ones to the left in the photo). I don't have a wiring sketch, sorry.
