Super Stable, Fast Response
Super stable and inexpensive Zigbee wall outlet switch. Integrates into Homekit thru Home Assistant. Far superior to WiFi connected switches. Never drops out.

S40 Lite DOES work with Hue Bridge, but…
I’ve seen lots of conflicting information in reviews and questions here, but as of November 2023, the Sonoff S40 Lite does indeed pair with and work with Hue. It was discovered perfectly during the “Add Light” search and it was discovered by Alexa immediately as well. I don’t use any of the Hue remotes / switches, etc., so I can’t speak for those (rumor has it, the S40 doesn’t play well with those but the S31 does). I do, however, use Flic and the S40 outlets work with the Hue/Flic integration (although Flic doesn’t seem to know the S40 is an outlet, not a bulb, so when toggling or setting the state it asks what color; I just choose “current”).Here’s the issue —- the blinking flickering LED light on the side button of the S40 Lite. I assume this is because the device isn’t paired with the Sonoff app, so it’s in a perpetual pairing mode? But that’s just a guess on my part. When the outlet is off, it’s a constant blinking green LED. When the outlet is on, it’s a rapid blinking red/orange and green LED. It is dumb. It is pointless. And, it is annoying! I plan to probably just paint over the LED or the button with white out or white nail polish or something to just block it out. I am sure the issue could be fixed with a software update, but of course, without using the Sonoff app, I probably wouldn’t ever be able to update the software anyway.Although I did take one star off for the blinking LED, value for money is exceptionally high! The Innr is still better in my experience, but it has been sold out and possibly discontinued. The S40 works, has an obnoxious blinking LED, but it way cheaper than alternatives. This is certainly a much better bargain than the Hue outlet and I really can’t see any advantage in buying one Hue outlet for the price of 3 of the S40.

Home Assistant Zigbee!
These did not work for me at first, and I was preparing to return them DEFEATED. For reference, I run Home Assistant on a RPi4, with the SONOFF Zigbee 3.0 USB Dongle Plus Gateway (TI CC2652P) available here on Amazon. When I bought that device mid-2022, it was loaded with firmware from July 2021. As a hopeful effort, I researched how to update the firmware of this device, and found Feb 2022 version was latest stable stack. After a bit of tedious work (you have to remove the sheath) and updating Windows drivers, IT WORKED! And while it took some time for my devices to re-connect after updating, I didn’t lose any of my previously connected lights or plugs. Now these CONNECT EASILY and WORK GREAT!!!!

Great, but poor instructions
These work great and I like that they are Zigbee, but wifi. Easy setup if you can figure it out. I didn’t want to use their app because I have a Smart Things hub to control it. Ultimately just plugged it in and had Smart Things scan for new devices. Simple. Used one to turn my Christmas lights on and off on schedule via Smart Things app/hub. The QR code on the back of the plug didn’t work for SmartThings setup.

Works well with Home Assistant and SkyConnect
I bought 4 pack a while back. Used two to replace mechanical timers for lights. Repurposed one for the Christmas tree and two more for indoor Christmas lights. I needed more for Christmas, so bought another 4 pack. Using them outside on my covered porch. I don’t anticipate problems with that since it’s always dry and will only be through Christmas.So far 6 of the 8 have worked right out of the box. They pair quickly with the SkyConnect Zigbee dongle.Update: 1 of the 4 is DOA. No light/No pairing. Literature in the box gave a tech support email. I will see how that goes.Update: SONOFF wants me to pay for shipping. So I will return through Amazon. Kind of a pain since I will need to return the working three as well.
