    Once I realized these are not a plug-n-play type of smart plug that requires third-party software I returned them immediately.

    These are easy to use. As Im getting older, I love telling Alexa to do stuff and she does it. Obeys better than my kids did, lol.

    My 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.

    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.

    I do like this device especially since its so much cheaper than other devices similar to it. But you do pay for that in some ways because it doesnt have a fast rate of updating. So it seems to freeze occasionally for 10 to 15 seconds and then other times it will report every 5 or so seconds. For my purposes it does just what I needed to.

    I have been assembling my own WiFi switches with Sonoff Basics and my own extension cords for a few years now. They have been extremely reliable with only one failure in over 35 units. I was happy to see these compact plugs with a 15 amp rating finally available. They integrate seamlessly with the rest of my switches and are fully accessible in the Alexa, Google Home and eWeLink apps. Options for Inching and energy monitoring are nice when needed. Build quality is excellent with a nicely finished case and solid feel. The indicator light is not obnoxiously bright.

    My intended goal for purchasing a dozen of these ugs was to integrate them with Home Assistant. I was able to successfully integrate them without too much fuss. The plugs work as designed and advertised. Additionally, I am able to either use the eWeLink app to see the each plugs overall power usage and control each plug. I plan on flashing these with ESPHome firmware so I reduce the need to rely on the Sonoff cloud. These plugs do have a LAN Mode option which enables them to reduce the need for the cloud, which I really liked. Overall, plugs are a 9/10 on my rating.

    Using them with Alexa, very reliable, never had a failure/need of reset. Easy setup and Alexa integration with the ewlink app. In the ewlink app you can turn on some features that Alexa do not have but still works with Alexa, additional bonus. E.g automatically turn off the device after xxx time has lapsed since power on, power on state, timers and loop timers. Very useful for my setup, controlling a water pump for my house remotely.

    I cracked this baby open as soon as I received it and flashed Tasmota onto it without any issues. Works great!
