Shelly 1PM WiFi built-in switch

This product is EOL (End of Life). The alternative is the Shelly Plus 1PM.

The Shelly 1PM is an affordable, compact WiFi in-wall relay switch with power measurement for your Smart Home system. It can be installed behind your wall switch, power outlet, or device. Its open-source nature allows integration with nearly any home automation system. Additionally, Shelly offers its own free app, enabling you to easily and cost-effectively set up a Smart Home system without the need for a Gateway/Hub.

Install the Shelly 1PM behind your wall switch, power outlet, or device, and connect via WiFi using the app. There is also the Shelly Button if you want to use the Shelly 1PM with a connecting cable for, for example, your desk lamp. You can then wirelessly control the switch or Button with the app from anywhere in the world, include it in smart scenes (scenarios), and set timers, such as turning on your lamp at sunset. Voice control with Siri, Google Assistant, or Amazon Alexa is also possible.

Works with:

_{* FIBARO Home Center 2, 3, or Lite via a Virtual Device/Quick App
** Apple HomeKit requires flashing or a Homebridge}

The Shelly 1PM relay switch supports 110-240VAC, 24-60VDC, and has a built-in ESP8266 with a 2MB flash chip. This allows you to flash your own or alternative firmware, such as Tasmota. For this, a USB-to-UART 3.3V and at least 350mA adapter is needed, such as our FTDI adapter. The best part is that you don’t even need to open the Shelly. Flashing is straightforward via the directly accessible pins on the outside.
NOTE: NEVER connect the Shelly 1PM to the power supply while flashing!

If you prefer not to use the free Shelly cloud service but still want to control your devices remotely, that's not a problem. The Shelly 1PM also supports basic MQTT (Message Queue Telemetry Transport) for reliable connections through a central broker: the MQTT broker. The devices involved communicate only with the broker and do not know each other directly. They do not need to know the IP addresses and technical details of other participants. Safe and reliable, with real-time monitoring and easy integration. Want to know more? Read our Shelly WiFi Switch Blog.
