Shelly Plus 2PM UL | WiFi & Bluetooth 2-Channel Smart Relay Switch with Power Metering | Home Automation | Roller Shutters Remote Control | Alexa & Google Home Compatibility | iOS Android App (2 Pack)

complete beginner
I am completely new to working with anything electrical and I was able to do this with a lot of trial and error.A few notes. I had a setup that had some 12-gauge wire. One of the 12-gauge wires would not stay clamped down and would come loose, so I scheduled return and got a replacement. For the replacement, the slot was able to clamp 12-gauge wire, but then a different slot couldn’t fasten the other 12-gauge wire.However, I discovered that both Shelly’s could clamp down on 14-gauge wire without any issues. I am not an electrician, but for my needs I concluded that 14-gauge was sufficient to power a couple light bulbs and a small bathroom fan.I also attempted to install the Shelly on a 3-way switch setup for two switches that have a traveler wire for each. I got one to work, but having trouble with the other due to some sort of conflict with the traveler wire setup. I have no reason to assume this is an issue with the Shelly; someone who knows what they are doing may not have problems with traveler wires.The hardest part of the entire thing was getting everything to fit and also make sure the switches align with the panel.I’d recommend picking up a voltmeter if you don’t have one to help figure out which wire is which. Also, you may need wire nuts of a couple different sizes and of course, the wires themselves of the appropriate colors, a wire stripper, and possibly some electrical tape. I got my wires at Home Depot.I like that family members can continue to use the switches as they normally would. Up-and-down switches may swap direction but, let’s be honest, this isn’t that confusing and for people for whom it is, a button can be installed instead.After installation, I was able to easily integrate with Home Assistant and set a bathroom fan timer once the light turns off after a shower. I also discovered that my bathroom bulbs somehow were not LEDs, so the power monitoring has already come in handy. For my other Shelly, I’ll use it to turn automate the garage lights. This has been one of the most rewarding personal projects I’ve done this year and I can’t wait to do more – in particular, trying to automate turning the lights off for family members that leave them on all the time. That said, I am hesitant to mess around too much with traveler wire switches until I have a better grasp of how to best use them with Shelly devices.Edit: After installing a couple more, if you have a hard time with getting the 12-gauge to stay clamped, I found that compressing the end with plyers to make more of a rectangular surface results in it staying nice and tight.The traveler wires aren’t hard to manage if you just install the Shelly on the load switch, assuming you have a live wire there.

Great product, but make sure you receive the correct one
Update: It turns out that I was sent the wrong product. I’m tempted to take a star off for that;had I not been paying attention, it would have put me at risk. I do really like the device. I installed this in a 4 gang box where I had combined two switches into one smart fan controller, and then connected the other two switches for 2 different lighting loads to the Shelly. It requires two hot lines in, as well as the two switches, the two loads, and the neutral, so it requires a lot of wire and is difficult to manipulate once connected. It remains to be seen what the life of the product is like, but so far, I like all of the features this has and will likely buy more.Original review: I waited for this listing for the UL certified version of the 2PM relay to come back in stock, ordered it, and received a device that is not UL compliant. Hopefully it was a mix up on the part of the seller, in which case, I will update my review. Otherwise, this device is not as advertised and should not be installed in the US. Check your device for a UL marking and understand the risks of installing a non-compliant device.

Easy to Install and Easy to Set up
Super easy to install and connected to WiFi without any problems at all.Fit my 12gage solid copper wire just fine.BEWARE – the set screws strip out SUPER easily. I stripped one but fortunately am only using a single circuit so was able to swap my wire to other circuit and using just that one now.Shelly App is easy to use so far – hopefully it won’t shut off features after using it for some time and require paid subscription, that would be not be awesome.

Yes please!
You can never go wrong with Shelly products.
