haavardw Posted November 22, 2023 Share Posted November 22, 2023 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?

Administrators Olsche Posted November 22, 2023 Administrators Share Posted November 22, 2023 the blue cables on O1-O4 are also neutral cables? That would be completely wrong wired. O1-O4 are the outputs to the consumer, S1-S4 are the external hardware switches that can be connected if available check also here: https://kb.shelly.cloud/knowledge-base/shelly-pro-4pm Quote Link to comment Share on other sites More sharing options...
