    I have a dozen of these to monitor and control roof heaters remotely. Also use to automatically turn off space heaters.

    After thunderstorm power outage, the products turns off on its own and doesn’t turn back on. Scheduling on the app doesn’t quite work all the time.hopefully Alexa can take over this. Wouldn’t recommend to put on always need to tbe on device.

    These plugs still have the ability to work with TASMOTA. They have to be opened and flashed via serial connections. Theres a few how-tos that show the process. Flashing TASMOTA helps me avoid relying on the cloud since I use Home Assistant on a RPi3.

    I first bought SwitchBot smart plugs thinking they would work with the Core SwitchBot integration with Home-Assistant, extremely disappointed in not only the broken integration, but also the terms of service from a company that has had a lot of recent YouTube praise. Unfortunately, it just shows the known ignorance and total abandonment of values in the name of convenience... Enter HACS and Sonoff; While Sonoff is also doing some data mining it is possible to run the S31 Smart Plugs completely local without the app or the cloud using HACS on Home-Assistant with no fooling with jumpers or fussing with flashing. Several recent HA forum posts and YouTube videos cover the procedure, just look for the most current so you can follow along more easily since the recent changes. Also, Stay away from the S40 if you use Home-Assistant. S31 is the way to go. Deducted a star for the shady terms of service that are getting all too common with IoT products. Otherwise, it would be 5 stars.

    I want to confirm that this product (SONOFF S40 WiFi Smart Plug) works with 220v-240v, I asked this question here in this product page if it supports 240v but all answers I got were guess work saying that it might not work (I wonder why people answer if they dont know), guesstimate was not the answer I was looking for, when it is written 110v I too can understand it might not work. I bought this one (knowing the risk of it not working) to use in my home country Nepal where electricity is on average 230v. So, yes this one worked successfully in 230v, I hope my answer will help people like me who will be looking to know about this issue.

    I am sure that others have been able to connect to this device, but I cannot. I followed the instructions exactly. I changed my wifi settings to 2.4. I have the router four inches from my phone and the device. I had order four of these devices awhile back but just got to the point where I needed to install for smart plugs so I tried just now to connect them. I went through every one and nothing. I have connected plenty of smart devices in my home. I am afraid that it was money wasted. If you buy these, I hope you have better luck than I.

    These are great plugs that provide a great deal of power usage info, are easily flashed to Tasmota (for local home automation), and are well manufactured. Have at least 8 in the house now, purchased over many years, and they keep working great.

    I own both the Wifi and Zigbee versions of this plug and am extremely pleased with both. After pullinn it apart (which is easy, no ultrasonic welds) the internal construction is very well designed and plenty safe enough to my reasonably educated eyes. The Wifi versions are straightforward to flash with your own firmware like Esphome or Tasmota without much trouble to run with your own system, and the Zigbee version integrates flawlessly too. I also like the form factor, with it leaving the other outlet available. Power measurements on the Wifi version are accurate when compared to my fancy measurement gear. And on top of all of that, the price is outrageously good? Yes, please.

    ***Not Tasmota compatible. This was my own mistake.*** These probably work perfectly in the advertised cloud interface, and integrating with Alexa, although I wont be using them in that capacity. I mistakenly purchased these to flash with the Tasmota firmware, as Im trying to make my own, locally-controlled smarthome environment. I was unaware that this new model is not based on the ESP8266 like previous versions were, but instead they are built on the BL602 chip. I found some talk of a similar custom firmware for BL602 IoT devices and I will be attempting to use it, but if you want to flash custom firmware onto a smart-plug, just get the older model and avoid this headache. These are nearly impossible (and probably dangerous) to disassemble, and the community around this chip is not nearly as large or well-documented as the ESP community is.

    Works great right out of the box. Using the Ewelink software, you are presented with all the parameters and easily connects to Alexa. Just change the name during the configuration to prevent Alexa from getting her tung tied up in a knot. The only downside is that unlike other Sonoff boards, the serial connection points on the board does not have through hole pads. Several flashers have damaged the pads trying to hook up the connections for flashing alternative software. Very good value for money
