Review: I like - These are great, installed easy, connect easy, works great.
Review: Great relay, easy to install with correct parts - Very easy to install once you have all the correct parts. After looking through some reddit threads, a Shelly employee recommended using 14 AWG wire for the relay, but my house uses 12 AWG wire basically everywhere. I used 14 AWG wire and some Wago clips to connect to the lead from the house and had no issues powering the relay. I installed this on an outlet to power a cheap wall mounted tablet with terrible battery management. The outlet now turns on and off to keep the tablet battery between 25% and 85% and has worked flawlessly. Getting the relay to go into Zigbee mode was a little more complicated than the instructions imply (I had to press the button harder than I thought, it felt like I was pressing hard enough but the relay wouldn't change radios), but once I had it in Zigbee mode, I was able to connect it to Home Assistant through Z2M with no issues. As a bonus, if you put this in Zigbee mode it will automatically act as a Zigbee repeater. I went back and forth between this and the mini for a long time, but the higher amperage rating for the 1PM Gen 4 is what pushed me over the edge. This is a great product, it installs very easily if you have the correct parts, it functions exactly as expected, and there is great support online from Shelly.
