Key differences between Shelly Plug US and Shelly Plus Plug US
The upgrades, in my opinion, have been all positive. In this case, the Shelly Plus Plug US adds the following capabilities to the original model:
- Bluetooth capabilities to make setup and pairing even simpler than it was before if you use Shelly’s app
- They can work in AP, client, and Bluetooth modes at the same time
- The ability to run MQTT and still have access to cloud control
- An increased number of webhooks triggered by device actions
- A brand new streamlined user interface
Even after adding these features, it still maintains all of the functionality of the Shelly Plug US, including an embedded web server, power monitoring, native integration with Home Assistant, and a 15 amp capacity that matches the ratings of most US household circuits.
Shelly Plus Plug US setup and use
Setting up this device is really just like all the other Shelly devices I have owned. Plug it in and then connect to its Wi-Fi access point and configure it via the embedded web server. You can also use the app, which is probably even easier, but I don’t use that. You can follow the same instructions I outlined for the Shelly 1 relay, but the user interface will be more modern.

The above screenshot is the home page of the updated interface. It shows watts, voltage, amperage, and protections. You can customize the overpower, overcurrent, and overvoltage protection cutoffs.
The rest of the interface for all of the functions and features has been similarly streamlined and modernized.
I should also mention that this smart plug does not block additional outlets, as you can see from this picture below


Integration with Home Assistant and other ecosystems
Integration with other ecosystems like Home Assistant, SmartThings, Homey, Hubitat, openHab, Google Home, and Alexa is natively supported. Home Assistant has a native integration that supports power monitoring and on/off features. The setup takes seconds.
You can always use the MQTT or REST API if you don’t have a native integration with your smart home controller of choice, or if you want to set up a custom integration.
Final thoughts
There original Shelly Plug US was already my go-to smart plug because of its price, reliability, easy integration capabilities, and power monitoring features. The Shelly Plus Plug US adds more capabilities while maintaining favorable pricing. It is my new go-to smart plug and it should be on your shortlist when you are looking for one.
