SONOFF S40 Lite 15A WiFi Smart Plug ETL Certified, Smart Socket Outlet Timer Switch, Compatible with Alexa & Google Home Assistant, IFTTT Supporting, No Hub Required -A Certified for Humans Device

I went with Sonoff because I needed the 220V support. The S31 has been great and Sonoff has added many great features. Helping keep track of power consumption and being able to set schedules for a fish tank light. I also have one for heating the tractor block. Its great to turn on remotely when I know I will need to clear some snow later in the night.

Bad advertisement of the product showing two but actually one comes in the package. Advertise one and sell one that it case close.

Easy to set up. Works with google.

Fairly easy to tear apart, solder wires between your FTDI, and flash. No app required, MQTT and away you go. I bought a slew of these to replace the Etekcity branded VSync switches I had. We had an internet outage that lasted about a week and NONE of my automations worked, so I bit the bullet and moved as many of my switches over to something that didnt require internet access to function. Home Assistant and MQTT with Tasmota for the win.

I have flashed the units with ESPhome, and am very happy with them. They have a great Wifi signal range, and am nothing but happy with them. To flash them I had to open them up and solder a few wires, and I was surprised to see the build quality of the PCB. They are using their own Wifi board, not like many other commercial units out there, which are using the standard ESP modules. And judging by the Wifi signal strength they did a very good job! Highly recommended if you want to have switched plugins which you can easily flash with alternative firmwares...

Smooth as glass, to set up and works flawlessly.

This item does what it says. Excellent!!

First off - the manufacturer does NOT recommend these devices for use outside. And they are not rated for exterior use. So do what I did at your own risk. BUT - they worked fine outside for switching Christmas lights for almost five weeks with just a few precautions. Here are some things I learned about these devices. First - they were extremely easy to set up using the free eWeLink APP. I linked them to my home WiFi (2.4 G ONLY) and added to the APP. This whole process went well and in accordance with the Sonoff instructions. I think it took less than 3 minutes per device to set up. I did all the linking and set up schedules from inside my home with the Sonoff devices just a few feet away from my WiFi router. How far away from WiFi? Once the three modules were connected to the APP on my SmartPhone I unplugged and carried them outside to three locations where I needed to control lighting. I covered the devices with a plastic bag (not tightly sealed - for air circulation) and/or inverted flower pot - see pictures. This was to provide at least some protection from my sprinklers, which run every week, and the occasional rain. One device was on a covered porch, still exposed to outside temperatures, wind, etc. but protected from direct rain or sprinkling. I didnt cover that one - as shown. The farthest device was 30+ ft. from the WiFi router. The other two were only about 12-14 Ft. from the router but outside of concrete and stucco walls. If you set up schedules for the outlets to turn off/on when the modules are near the router, you can then carry them outside the range of your WiFi and they will still operate just fine, since the schedules are actually downloaded to the module once set. Put another way, the modules do not have to communicate constantly via WiFi to do their job. However, if you try to change the schedule WHILE the Sonoff is out of range of WiFi, you will not be able to do that. I did not have that problem with either of the modules, even the one that was about 32 away. It stayed connected to WiFi for the 4+ weeks it was in use. I have been a fan of Sonoff for a long time. My experience has been that they are very reliable and cost-effective Internet of Things solutions. The S31 did not disappoint. I have used other Sonoff devices with IFTT but did not do that with these. Also - the modules did not loose their schedules when power was occasionally interrupted. And they reconnected immediately and automatically to the WiFi as soon as power was returned. If you need to control an AC operated device from far away and have WiFi somewhere near the devices, these will do a great job for you, particularly if you want something that doesnt require a whole lot of Geekiness to get working! Just remember - they are not really meant for use outside ;-)

Got these because they are easy to open and easy to flash with Tasmota so I dont need to go through Sonoff servers to control my lights. They arrived on time, were easy to get working and as I type this, they are controlling lamps in my house controlled by a Raspberry Pi running Node Red over MQTT while I am out of town. So far, I am a happy camper.

Set up was easy with the Ewelink app and then connecting it with Google Home. They wont block above or below it
