Yes, it is a US plug. I use mine at Christmas time for my tree.
With a clamp on amp meter and 10x coil, got a measurement of ~7mA in off state, ~11mA in on state. The relay draws ~4mA (from 11 - 7). At 120VAC this would be 0.00084 kWh and .0011 kWh respectfully. At $0.12 per kWh, for 1yr. continuous would cost $0.88 to $1.40 per year.

The S31 (not the 'S31 Lite') also gives current power voltage, amperage (10mA increments), and wattage (10W increments), and daily power usage bar graph, basic but useful.
I think they have that listed just as being a part of their 'ecosystem'. I know they have security cameras that watch your house inside & out fort 'smart detect'. I think this is a generic picture they use on all their product descriptions. I have this and there isn't a camera anywhere in the plug. I took mine apart ?… see more I think they have that listed just as being a part of their 'ecosystem'. I know they have security cameras that watch your house inside & out fort 'smart detect'. I think this is a generic picture they use on all their product descriptions. I have this and there isn't a camera anywhere in the plug. I took mine apart I was seeing some odd out calls. Off topic. This work and work well. Every ecosystem I tried worked extremely well. I don't use IFTTT though.

Fairly easy to load a custom firmware
I purchased this device because it was capable of running custom firmware like Tasmota and ESPHome (which do not require a cloud connection). The installation process was fairly easy. The gray side piece can pop off, and then two edge pieces slide out. After that just remove a few screws and it opens. I was a little disappointed that the serial connection points were not holes like some of the other Sonoff products I have used. However, I managed to apply the firmware without soldering by taping together a row of jumper wires and pressing them firmly against the contact points while the initial flash process ran. After that, I simply put it back together and it’s working perfectly with the custom firmware.08/29/2022Verified Purchase
Tasmota Flashable - NO power monitoring
Fairly easy to tear apart, solder wires between your FTDI, and flash. No app required, MQTT and away you go. I bought a slew of these to replace the Etekcity branded VSync switches I had. We had an internet outage that lasted about a week and NONE of my automations worked, so I bit the bullet and moved as many of my switches over to something that didn’t require internet access to function. Home Assistant and MQTT with Tasmota for the win.08/13/2022Verified Purchase
Practical, affordable, easy to install
This hooks up to my Google ‘home nest’ and ‘Alexa’. Simple to install and control. I’m buying more.07/24/2022Verified Purchase

Flashing Tasmota (for Home Assistant etc) - Some tips
These work great for flashing Tasmota, but you need to be familiar with the flashing process. Here are some tips:
– Highly recommend those rubberized ‘Mini probe test leads’ to clip between the board and FTDI flasher to avoid the annoyance of doing a hard solder just to flash the device.
– Any basic FTDI-type USB flasher will work, just make sure it can provide 3.3v (make sure to set it to 3.3v before connecting!). There’s a cheap FT232RL $5 one on here–make sure you have any requisite USB connector for it (mine needed the uncommon USB mini adapter).
– Opening the Sonoff isn’t terrible difficult, use a spudger or mini flathead screwdriver to pop off the grey cap on the side facing the plug. Remove the white sliding things, and be gentle doing the 3 screws since they strip easily.
– Grab the latest tasmota.bin from Github. There are multiple tools that can flash it, I used ESPHome Flasher.
– Flashing: 1. Connect GND, RX, and TX probes between the Sonoff and your FT device, but don’t connect VCC just yet. GND goes to GND, but RX goes to TX and vice versa! 2. Plug in FT device to computer. 3. HOLD DOWN button on the Sonoff device and connect VCC–if your FT device has LEDs they should flash but Sonoff should not. 4. Refresh ESPHome Flasher and it should detect your device on the USB port. Load the firmware .bin and flash it. 5. If successful, put the Sonoff back in its housing and plug it into an outlet to test. Use your phone to connect to the temporary AP so you can give it your wifi details. That’s it! Future updates can be done OTA.06/02/2022Verified Purchase
