I previously put together a 'smart' outdoor extension cable to control lights in my yard using a smart switch from another manufacturer. For various reasons I decided to replace this switch and opted to use a Shelly 1 as the new switch.
It took me a while to figure out which wire is which in the cable (Black - Live, White - Neutral, Blue - Ground). Based on others who have done something similar I attached the incoming live wire to the L(-) terminal while connecting the incoming neutral to the N(+) terminal together with the neutral wire for the ouput side. The live wire for the output is connected to the O terminal. I have attached a picture of the wiring.
After a lot playing around with the Shelly app I eventually managed to see and control the switch from my phone. However I don't seem to have any power at the receptacle terminations on the power cord. I'm unsure whether this is a problem with my wiring of the Shelly or with the power receptacles themselves (the cord has been outdoors for quite a while). I realize that I can use my multimeter to test for AC power at the switch by connecting the probes across the live out wire and the ground however I must admit to being somewhat of a wimp when it comes to testing live electrical wires!
Update: I used a non-contact voltage tester that appears to confirm that there is AC voltage on the black output lead (tester turns red and beeps). What is strange is that the on/off switch on my phone appears to be reversed, i.e. pressing the switch when it says 'turn on' appears to turn off the switch and vice versa.
I'd appreciate any feedback regarding my wiring and/or how to troubleshoot why there is no power when I connect lights to the power receptacles on the outlet of the extension cord.
