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

Sonoff has a reputation for being very friendly to developers and home-automation enthusiasts. It is a very common practice to flash alternate hardware on these. Of course, doing so voids any sort of warranty and eliminates the possibility of sending them back, so its always done at the purchasers own risk. That being said, Ive had no problem with other Sonoff products. However, these are a disaster. I destroyed one just trying to get the screws out. They are in far tighter than could ever be necessary. Another one I destroyed by trying to solder little wires onto the pads for programming. One of the pads came off. All of these might still work with the original firmware, but they are completely useless to me that way. They require Internet connectivity to work, so what happens when my crappy satellite internet fails? I have to crawl around under tables and behind furniture to find the little buttons that I have to press just to turn things on or off. This has been a major disappointment for me. I thought Sonoff treated their customers better than this.

Facil de usar, muy simple

I love the sonoff plug I use it to automate my Christmas Tree Will definitely be buying more

Running the lite and non-lite model all over the home. All models running Tasmota and integrated with Home Assistant. Very easy process, works great.

Lo puedes integrar a Alexa

Worst buy ever... I thought I was getting a great deal with the 4 pack... Wrong had to return them as they would not pair. Im in IT so I know how to pair... Junk as I see it on my part...

While this product works to control objects just as well as the Original S31. BEWARE, it is the S31 LITE which means it will NOT do any power monitoring for you. It is just a small switch. Looks wise on the exterior, it is indistinguishable from the power monitoring version. In the eWeLink app, it will look like any non-power monitoring switch you may have like an S20 or S26.

I own several Sonoff products, switches and plugs. They are flawless. Ive never had a problem. They are simple to setup and easy to use. Alexa integration works really well too.

I accidentally ordered this version (the lite, which doesnt include energy monitoring) but was still much more convenient than than sonoff basic normal use due to the integrated plug. PLUS tasmota is still easy to install

Dependable smart switch. I have it paired to Smartthings and Home Assistant. The only issue I had was the initial set up but thats because I have a mesh wifi system where the 2.4 and 5 GHz channels share the same name.
