Product detailed description

🔗 Connect and Control with Ease

The Shelly Plus Addon is an advanced sensor interface designed for the Shelly Plus module series. It allows you to wire various sensors directly to your switching modules and use the measured data for home automation. While it's most commonly used for DS18B20 temperature sensors or DHT22 temperature/humidity sensors, its capabilities stretch far beyond that.

A major benefit is its support for analog sensors and standard low-cost Arduino accessories. Using these affordable components, you can connect almost anything into the Shelly ecosystem. Monitor water levels, garage door status, soil moisture, wind speed, rain presence, light intensity, or noise levels easily.

How the Shelly Plus Addon Works

This product does not function independently. It must be attached to a host module from the Shelly Plus series (such as the Shelly Plus 1, Shelly Plus 1PM, Shelly Plus 2PM, or Shelly Plus i4). The Addon simply snaps onto the top of the host module, providing screw terminals to connect the wiring of your required sensors.
