I'm wanting to add a shelly v1 to one of our wall lights but after taking it off I can't work out what is happening here! The wiring doesn't seem to match any diagrams I can find, what is this called and why isn't the light permanently on? wiring

  • why not always on? there's a switch between the photo and the breaker box. That looks like a typical fixture box. Wouldn't you want the shelly replacing a switch? If you are going to use it at the fixture instead, yes, you will want constant power to the fixture. – dandavis Dec 14 '20 at 18:37
  • The switch has three cables going in and is pretty full so was hoping to put it in light, but I don't get where the two wires are going, the diagrams i can find for end of a loop for example have a switched live in the light but not sure if I have that here, and ones with loop to another light have thress wires? Like as they join if it was going to another light it would only work if this one was on? If it doesn't then why doesn't it return on same cable? – Dan Turner Dec 14 '20 at 18:42
  • Think of it as a splice to simplify. If you want to switch only that light, splice after the "busbar". If you want to control all the lights on the run, splice the dark blue and red wire into the shelly. Note that you can't use the wall switch after this, so it should be removed for human/EMT factors. – dandavis Dec 14 '20 at 18:51
  • There is only one light from that switch so is it effectively just joining the two cables together at the point of the light for some reason? – Dan Turner Dec 14 '20 at 18:57

    Yeah that still works, I think that solves my confusion thanks! Actually looking at room I think there was another light on the other side of the fireplace but the previous owner has put a built in tv unit over it! – Dan Turner Dec 14 '20 at 19:13
