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 wanted to use this for bedroom light, which I can shut off from cellphone from bed, and start-on by toggling the wall switch the next day (by setting default-power-restore status = on in the setting). Working great!

Trash product, I literally tried every possible way to get these to work and nothing helped. I literally just threw them away. It was worth the trouble to return them.

Works well to turn on and off any AC powered plug-in device. Integrates easily through eWeLink and Siri.

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

A plug requires to use my phone number? How safe they can guard my info？!

I worked at it a long time!

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.

Lo puedes integrar a Alexa

Its not 220v

Enclosure design is excellent for getting access to innards to flash custom firmware (Tasmota in my case). Not glued together but held together with snaps and screws. Build quality is good. Did not use stock software to control with Alexa but flashed firmware for local control (device does not “phone home” to China. WiFi reception is strong with the ESP chip (stronger than many comparable devices). So far, very pleased with design and results. All together, I’ve purchased 8 of the S31 (both Lite and EM versions) and they all work (some other brands were somewhat hit or miss). Good QC.
