Shelly Smart Plug, Smart Home WiFi and Bluetooth Outlet with Power Metering, Works with Google Home, Alexa, Home Assistant, Smart Socket, No Hub, Easy Setup, Remote Control, Plus Plug US

I believe this is the only smart plug that anyone should ever use. It supports everything except for Zigbee, but they have models that do, just not this one. The build quality and the CE or UL certification far surpass the others, and that is important to prevent fires in your home. Many Chinese products on Amazon state UL listed when they are not; you can search for UL-certified products on the UL website, and you will see that sellers on Amazon just state that without really being certified. Shelly is NOT one of those; they build quality pro-grade devices. As for compatibility, you can use these with every Home Automation system I know of; these are fully open devices. You can even use your own certs on these to really lock them down if you want to. Shelly gives you full control of the hardware. So to sum it up, these are the safest devices to use, the most compatible devices to use, and the best performing devices to use.

I’ve been using the Shelly Plus Plug US to control my indoor grow lights, and I couldn’t be happier with its performance. While I’m not a licensed electrician, I can confidently say this smart plug is rock-solid when handling high-power loads. I’m running a 1600-watt lighting setup, and the Shelly Plus Plug handles it without breaking a sweat — no overheating, no flickering, just consistent, reliable power. Setup was truly plug and play. It connected to my Wi-Fi quickly, and the Shelly app made scheduling and automation a breeze. I can easily turn my lights on and off from anywhere, monitor energy usage, and even create advanced routines if I want to. Whether you're managing a grow room, automating appliances, or just looking for a high-quality smart plug that can handle real power — this is the one to get. Shelly nailed it.

I love this product. First heard about this from a Raspberry Pi internet monitoring setup where the author also monitored the power consumption of his satellite gear with a Shelly plug. I grabbed one and installed it on the pump for my 25,000 gal swimming pool. Pump pulls 989W consistently, well within Shelly's limits. I can now monitor the power consumption from a Pi and detect things like a burst hose or low water level based on feedback from the pump. I can also turn the pump on and off remotely which makes vacuuming by myself a breeze. I have bypassed the old mechanical time switch my dad mounted on the wall when I was a kid and now I schedule the pump operating hours in the Shelly app. I love this product and will be buying a few more! Very capable and has a whole slew of communication options including wifi, bluetooth, websocket. and MQTT. Impressive device in a tiny little package!

I purchased this device to measure the wattage consumption of my homelab. While I had an approximate idea of the overall power draw, I wanted to track peak usage and ensure the voltage remained stable "enough" for my equipment. This is an excellent "smart" alternative to a traditional Kill-a-Watt. It integrates seamlessly with Home Assistant and offers customizable settings for individual outlets. From what I can tell, it’s based on an ESP8266, and the firmware has received multiple updates—always a positive sign. The default Shelly App also retains a surprising amount of historical data, even if you choose not to link it to Home Assistant. Plus, it can be triggered and updated through Home Assistant, which adds a layer of flexibility. I appreciate how companies are embracing open-source principles—this device feels like a great example of that. It’s reliable, feature-rich, and easy to customize. TLDR: ✅ Accurate wattage tracking with peak monitoring ✅ Seamless Home Assistant integration ✅ Regular firmware updates for the ESP8266-based device ✅ Shelly App provides detailed historical data ✅ Open-source-friendly design and customization Recommendation: Perfect for DIYers and homelab enthusiasts looking for a smart, open-source power monitoring solution.

I thought it was just going to allow me to turn on/off the outlet remotely. But it does SO much more. (Things I didn't expect.) - It shows the real-time power usage (V and A). Great for determining how much power a UPS, power strip, or individual device is using. - It includes a counter for tracking Watt-hours. (You can reset the counter for measuring over a specific period.) - Built-in timer and supports scripts for doing really customized tasks. (E.g., if the following conditions are met, then turn on or off the outlet. For example, I can have it query my digital thermostat and turn on a fan.) The best part: while it can be used with cloud services (Siri, Alexa, Google Home, etc.), those are OPTIONAL. I use it offline as part of my local office network. Building something like this from scratch (e.g., esp32, voltmeter, ammeter, power relay, etc.) would cost way more than this little device, and it wouldn't have as nice of a user interface. My only wish? I wish they had a two-outlet version.

Bought this because you can use and API to manage it. I was going to use this to reboot my home internet router with a python application if there is a loss of connectivity. When the device is on the wifi AND there is an available route to the internet, it works without issue and I can control it no problem. If the device is on wifi AND the internet is not available, the device disables it's communication on the wifi network, so you can't grammatically communicate with it at all. can't even ping it. When the internet connection on the wifi network is restored and there is a route to the public internet, then you can interface with it again. I opened a case with their support and it took them forever to respond, when they did respond they told me it's normal for device on the wifi network to not be reachable when there is no internet. lol, no Shelly support, all devices on the wifi network will still be able to communicate with each other, they just wont be able to access the internet. The only device that did not work and could not communicate without WAN availability was the smart plug. It's obvious that their device want to talk to the mothership and is disabling features/services if it can't, which is silly, a bug, and ridiculous that they can't even understand basic troubleshooting. I found lots of other people complaining of the same kinds of issues on the net.

These are fantastic. Flawless web interface (starts off as its own AP, which can be disabled later after wifi access is established) Reliable LOCAL (wifi) Control ... Disable'able if you want to - I dont know why you would though. OPTIONAL Cloud Control Optional Bluetooth control Optional MQTT/RPC Control Web-based or Automatic firmware upgrades NTP time updates Works flawlessly with Home Assistant Someone really thought this device through thoroughly. After setting up thousands of different IoT devices, I am very impressed. This is the gold standard of what IoT devices should be.

Did exactly what was advertised. Gave me an out of band option to reboot zigbee home hub.
