connecting DS18B20/DHT22, 0-10 V analog, ±15 V digital, and dry-contact sensors for monitoring and automation in homes or industry.
Shelly Pro Sensor Add-on is not a standalone device and must 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 the Pro Sensor Add-on.
