> 24 hourBest thing about this device is the ability to reflash with Tasmota firmware which then works with both HomeAssistant and MQTT based home control and automation systems. You can utilize one system for power monitoring and the other for control once the unit has been flashed. Very good support by the community for using the part.

> 24 hourThe appeal to this model is the ability to open them and hack them - great for automation. They didnt play nice with my router. 2 of the 4 kept going offline and I had to reset them to get them back.

> 24 hourI 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.

> 24 hourI 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.

> 24 hourI just needed good, wireless devices that allow intelligent, accurate monitoring of electricity consumed by a device. This device was the epitome of disappointment. During the WiFi setup (2.4 GHz), it insists on getting your LOCATION INFORMATION. No thanks. AND you have to create an account to use them. NO THANKS AGAIN. No iPad specific app, only iPhone. Three strikes. Done. No more. For example… To pair, the blue LED blinks 2 dots and 1 dash. Then press the button for 5 seconds and it changes to… 2 dots and a dash… AGAIN. This is 2022, I have no need to be proficient in Morse Code. These things are not even heavy enough to be used for paperweights. I just wasted $20. You have been warned.

> 24 hourI installed this product on an in-the-water boat to monitor and control a 1500W heater, using the Smart Life app. The initial configuration was a bit difficult, but it worked through the manual pairing procedure. A seemingly unlimited number of on/off cycles can be programmed by the day of week and hour, or control manually via the app. It relays wattage in use and current voltage at the plug (whether on or off). It will report total kW-hrs used over a month and cost if you input cost/kW-hr. I have several wifid temperature modules mounted in the approximate same location on the boat as well and have some connectivity difficulties with them. There has been no connectivity issues with this plug/adapter and it has been very reliable.

> 24 hourThe internet at my house is unreliable. Days of outages in March 2023. So counting on cloud based tools is a non-starter. These plugs are easy to open up, reflash with Tasmota software, and control through a website hosted on each plug, or via an MQTT server. Im happy with the plug hardware being easy to update, and happy with the new software.

> 24 hourMy wifi auto switches your devices between 2.4GHz and 5GHz, so I cant use this switch unless I dedicate a an old phone. I put my phone on the 2.4GHz band to install it and it worked. However, I cant leave my phone on that band. When I switched back, I couldnt connect to the device. I have other smart devices that require 2.4GHz signal in the house but not on your phone. Bad software design.
