Shelly Temperature Add-on for Shelly 1-1PM

This product is EOL (End of Life). We now have the Shelly Plus Add-On as its successor.
Please note: this works only with the new Shelly Plus series, regardless of which model.

With this Shelly Temperature Add-on for the Shelly 1 or 1PM, you can connect up to 3x DS18B20 waterproof temperature sensors or 1x DHT22 temperature and humidity sensor (sold separately). It's useful for accurate temperature measurement in your aquarium, underfloor heating, or for measuring humidity in the bathroom for smart ventilation.

Create smart (cloud) scenes based on temperature and/or humidity, and view the history in graphs. The Add-on supports MQTT, CoAP, and API.

The separately sold 1-meter long DS18B20 temperature sensor is digital and has no signal issues even over longer distances! The digital temperature sensor is fairly accurate (± 0.5 °C across much of its range) and can provide up to 12-bit precision from its built-in digital-to-analog converter. It works great with any microcontroller using a single digital pin, and you can even connect multiple sensors to the same pin, each with a programmed unique 64-bit ID to differentiate them. Usable with 3.0-5.0V systems.

The separately sold DHT22 is an affordable digital Temperature and Humidity Sensor. Using a capacitive humidity sensor and a thermistor, it measures the ambient air and sends these values as a digital signal to the data pin connected to the Shelly Add-On (soldering provides the most reliable connection). The sensor is easy to use but requires precise timing to record data accurately. Measurements are taken every 2 seconds;

• Accuracy: 0.1
• Humidity range: 0-100% RH
• Temperature range: -40 ~ 80 ℃
• Humidity measurement accuracy: ± 2% RH
• Temperature measurement accuracy: ± 0.5 ℃

NOTE: You cannot combine the DS18B20 and DHT22. You can only connect 1x DHT22 sensor.
There is also a DS18B20 with 3m cable available separately.
