DS18B20 Sensor
£5.79
The DS18B20 is a temperature probe designed to add temperature sensing to compatible Shelly relays that support an external sensor addon. It plugs into the Shelly 1/1PM temperature addon or a Shelly Uni, letting you trigger automations or logging based on measured temperature rather than relying on the relay alone.
- Compatible with Shelly 1/1PM temperature addon
- Also works with the Shelly Uni
- Wired probe format for external temperature readings
- Allows temperature sensing at a distance from the connected device

Where you'd use it
Hot Water Cylinder Monitoring
Strap the probe to a hot water cylinder or boiler flow pipe and wire it into a Shelly Uni to log temperature over time.
Freezer Temperature Alert
Combine it with a Shelly 1/1PM temperature addon in a garage freezer so a rise above a set threshold can trigger a notification.
Underfloor Heating Zone Reference
Use it as an external temperature reference wired to a Shelly Uni at an underfloor heating manifold to check a zone is actually reaching set point.
