FAQs
What is the primary purpose of the Shelly Plus Add-On?
The Shelly Plus Add-On expands the functionality of Shelly Plus and Gen3 relays by allowing the connection of various external sensors for environmental monitoring and advanced automation.
What types of sensors can be connected?
It supports 1-Wire sensors like DS18B20 (temperature) and DHT22 (temperature/humidity), as well as a wide range of analog and digital sensors such as photoresistors, PIR motion detectors, soil moisture sensors, and reed switches.
How is the Shelly Plus Add-On powered?
It is powered by the connected Shelly Plus or Gen3 device via a 3.3 V DC connection.
Can I connect multiple temperature sensors?
Yes, you can connect up to five DS18B20 temperature sensors via the 1-Wire terminals.
Where can the Shelly Plus Add-On be installed?
It is designed for indoor and outdoor use and can be mounted inside standard electrical boxes alongside compatible Shelly devices.
Is the Shelly Plus Add-On compatible with third-party relays?
The Shelly Plus Add-On is designed specifically for use with Shelly Plus and Gen3 relays. Its compatibility with third-party devices is not guaranteed.
What are the operating temperature limits?
The operating temperature range for the Shelly Plus Add-On is -20 °C to 40 °C.
Troubleshooting
Sensor readings are inaccurate or absent
Verify that the sensor is correctly connected to the appropriate terminal (1-Wire, analog, or digital). Ensure the sensor type is correctly configured in the Shelly app. Check the sensor itself for damage or malfunction. Confirm the Add-On is receiving power from the connected Shelly Plus/Gen3 device.
Add-On is not detected by the Shelly device
Ensure the Add-On is securely attached to the Shelly Plus/Gen3 device and powered on. Restart the Shelly device. Check the connection cable between the Add-On and the Shelly device for any damage.
Automation rules based on sensor data are not triggering
Double-check the conditions set in the automation rule within the Shelly app. Ensure the sensor threshold values are correctly defined. Verify that the sensor is actively providing data that meets the rule's criteria.
Device overheating
Ensure the Add-On and the connected Shelly device are within their specified operating temperature range. Check for adequate ventilation within the electrical box. Avoid direct sunlight exposure if installed outdoors.

Setup, Compatibility & Care
Setup: The Shelly Plus Add-On is designed to be mounted alongside a Shelly Plus or Gen3 device within a standard electrical box. It is powered by the connected Shelly device via a 3.3 V DC connection. Sensor connections are made to the designated 1-Wire, analog, or digital input terminals on the Add-On. Configuration of sensor readings and automation rules is managed through the Shelly app or web interface.
Compatibility: This add-on is compatible with all Shelly Plus relays and Shelly Gen3 devices. It also supports a wide range of common Arduino-compatible sensors, including DS18B20 temperature sensors, DHT22 temperature and humidity sensors, photoresistors (LDRs), PIR motion detectors, soil moisture sensors, and reed switches.
Care: The Shelly Plus Add-On is built for indoor and outdoor use within its specified operating temperature range (-20 °C to 40 °C) and humidity levels (30-70% relative humidity). Keep the device clean and free from dust. Ensure proper ventilation within the electrical box. No regular maintenance is typically required beyond ensuring connections are secure and the device is operating within its environmental limits.
