I use this to control my outside string lights over my back deck. I use IFTTT to turn on at dusk and off before sunrise. Works well.

Works finally, but it was very long process to connect to my wi-fi.
Only managed to connect in compatibility mode, but even with that, it took me hours until finally connected it to my network.
I have a lot of smart devices (over 30) and all kind, like ZigBee, Z-wave and some wi-fi, and I never had so much trouble connecting. Router was on the other side of the wall.
They should place the LED on the same side as the switch. I have installed this outlet under the roof, for Christmas lights, and it was super hard to see the LED status. I had to do it in the dark, to see the LED light bouncing of from under the roof.

Loved the software side of the product. Two downsides, it IS NOT WATERPROOF and Changing WiFi is a pain. I see they aren’t selling it anymore and these are probably the reasons! Disappointed in the hardware side of this product.

Works great! I actually installed Tasmota firmware on the unit. It talks to a MQTT server that's controlled by Node-Red on a raspberry pi that controls my Christmas lights. (The stock firmware and software would have done this but I have to mess with stuff ;) ) I have a few other sonoff units that I considered for the application but by the time I bought an outlet and box this was cheaper and easier.

This little wifi outlet is great, I have used the indoor versions of these and wanted to use them outside, but was always worried about the weather and them getting wet, Now there is no more worry, now I can control anything from security light to to christmas light over the holiday period. A regular outlet is ok, but being able to control it from inside the house, or anywhere in the world is much better.
