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

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.

Sumamente sencillo de instalar y configurar con Alexa, una configura dos, funcionan a la perfección, hyper recomendado

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

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.

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.

August 2021, the pin pads are easily accessible, no trouble flashing Tasmota to it. Disassembly was easy and non-destructive. Great build quality and extremely responsive. I’m running 6 of these, never had a problem.

Cant leave a bad review because they seem like typically Sonoff quality and it was my mistake, just know they cant be flashed to Tasmota. Go for the S31 version if you want that instead

This is my fourth son off product and I’m very pleased
