    Bn Link used to sell these with a power meter but I contacted them and they don’t offer the meter option anymore because of a chip shortage. These are a couple bucks more but the power meter is the feature I really like.

    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 were not so easily added to the Alexa controlled system. Instructions did not track with the way I had to install them. The plug is large and the light/button, instead of being on the front, is on the side which means horizontal outlets, depending on orientation, may make it impossible to see the status light.

    Q: Why would my firewall block a well known Ch___ government monitoring site? I guess Im a suspicious person by nature, but while setting up my Sonoff Type B wifi Smart Plug (S40TPB) I got enough red flags to make me return it. A), the instructions ask me to turn on my phones location settings and share my phones location with the Smart Plug. OK, yellow flag, but I suppose that makes sense - sorta. B) Be sure that the MAC address of the device is not on the BLACKLIST of your MAC management [I presume they mean my network firewall. Blacklisted equals a huge RED FLAG for me. C) Please contact your ISP [Internet Service Provider] and confirm our server address is not shielded [I presume they mean blocked]. cn-disp.coolkit.cc and other coolkit.cc hostnames are basically in C___a, right? Quick question for anyone reading this far; why does a blacklisted server in C___a needs to know when I turn your lights on and off? After a few minutes of digging around to see where my turn the light on requests were being routed to, I quickly unplugged this little monster and promptly brought them to my nearest UPS store for a full refund.

    I really wanted a smartplug with good energy monitoring data. However, this device/app only gives you historical data in per day units and only in kilowatts. What about per second/min/hour? Or amps/milliamps/kiloamps? Or regular watts? As such, this only really is useful for recording your daily energy usage. As such, this is useless for someone like me, who is looking to observe changes in electrical consumption when I plug in/out any device in the house, or when I turn on/off a fan or anything else. The data also updates very slowly, taking a minute or two to read the energy consumption, and is incorrect. I have another energy monitoring smartplug that gives consistent rapid accurate data, and the SONOFF branded one is always off. This gets 1 star for being somewhat functional and an additional star for the price per value, but at 2/5 stars, I recommend you look at other options.

    These are great products to control devices and monitor power consumption remotely. I flash them with the Tasmota software package and then monitor/control them with Node Red. They appear to be certified to the equivalent of UL, though it would be great if they went with UL directly for the US market.

    After opening them up and flashing Tasmota firmware to the onboard chip, I can now control these via MQTT and my home control system without an internet connection needed. A VPN connection handles off-site control. I am currently using them to schedule lamps and equipment chargers periods of activity.

    I bought a single S31 to replace an unreliable Fibaro Z-Wave switch. I never even bothered to use the original S31 firmware. I took it out of the box and flashed it with ESPHome under Home Assistant. Worked great the first time with no surprises. The power monitoring seems to work, but I havent bothered calibrating it. If it continues to be reliable over time, I will definitely buy more of these.
