The Shelly Pro Sensor Add-on is a galvanically isolatedsensor interface for Shelly Pro devices, designed for compact DIN railinstallation. Use it to connect 1-Wire, 0-10 V analog, digital, and dry contactsensors, turning your Shelly Pro into a powerful multi-sensor hub for precisemonitoring and advanced automation.
*Shelly Pro Sensor Add-on is not a standalone device andmust be connected to a compatible Shelly Pro device for power and operation.Compatible devices: Shelly Pro 1/2, Pro 1PM/2PM, Pro Dimmer 1PM/2PM, Pro EM-50,Pro 3EM, Pro Dimmer 0/1-10V PM. Pro host device needs FW version 2.0 to run thePro Sensor Add-on.
