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

One of my favorite smart home devices! Extremely versitile. I’ve only had one fail and it was my fault because of a fantastic feature they have. They let you put your own code. Own logic. Etc. In them. It’s fantastic. Rarely does a company let you reprogram it. The module still works. I just need to reset it. I’ve bought at least 20 at this point and I always look for anything new they sell. And every automation system I’ve seen has integration that is seamless. 100% favorite product line.

Absolutely excellent

Husband is putting these on every wall socket.

I like the fact that these can be installed behind the switches in the junction box to add smart home functionality to existing lights. I don't love that when I upgraded the firmware, I had to take it back out to reset it since it quit working.If you are installing these, do yourself 2 favors:1. Install them so that you can get to the reset switch without having to remove anything but the cover plate (rear facing forward with the reset button not covered by the switch).2. Once installed, before you put everything back in the junction box, upgrade to the latest firmware and do the reset.I also would LOVE to see Shelly put out something with dimmer functionality like this.The app works great.If you are wondering how this works, if you turn on the light with the switch itself, it comes on. If you turn it off with the switch, it goes off. If you turn it on or off with the app or home automation software, it doesn't matter which position the physical switch is in. If you turn the light (or fan) on with the switch, and turn it off with the app, it will turn off, and the switch will not work again until you turn it off and back on, but the app works anytime regardless of switch position.Also, if you turn a light (or fan) on with the app, to turn it off with the switch you just turn the switch on, then off.I love that this model shows you the wattage. I was surprised how little wattage my ceiling fan actually uses, even on high.Also, if you are like me and want to take the cover off to see what's inside, make sure you don't lose the TINY reset button, which can fall out.These use a mechanical relay, so you will hear a tiny click noise when you turn something on or off. It's not very loud, and I don't think it will really bother anyone - just a callout.

I'm using these, with Home Assistant and an Aquara presence sensor to save power in my two car garage. I'm using them with LED retrofitted, quad T8 fluorescent housings. Still have switch control, but the auto off with the presence sensor will save a lot of power.
