Shelly Plus AddOn

Discover the Shelly Plus AddOn - a versatile and precise sensor interface for your Shelly Plus relays. With the Shelly Plus AddOn, you can connect up to five DS18B20 temperature sensors or one DHT22 sensor for temperature and humidity measurements. The Shelly AddOn is delivered without sensors, which need to be ordered separately. Thanks to galvanic separation and compatibility with most Arduino sensors, you can connect your sensors safely and flexibly. Use the analog and digital input to capture various parameters and create complex automations for maximum efficiency. For example, you can use the digital input to monitor the status of your garage door with a reed switch sensor and ensure that it is always closed. Or connect the Shelly Plus AddOn with a Shelly PM relay and a temperature sensor to optimally control the energy requirement for your instantaneous water heater and automatically switch it off as soon as the desired temperature is reached. Use the Shelly Plus AddOn for diverse applications and enjoy precise measurement and control in your smart home.
