Shelly Plus Add-on.
Setup is simple...
Easily connect Shelly Plus Add-on to your favourite Shelly Plus Relay module.
Monitor, control and create automations in your Shelly compatible hub, app or software.
Open / Close Sensor.
By combining Shelly Plus 1PM and Add-on with two DS18B20 temperature sensor probes, you can easily measure the precise temperature inside your aquarium, as well as the room temperature. Additionally, you can connect a liquid level sensor to the Add-on, and always be sure that the water level is at its optimal level.
Outdoor motorised awnings offer pleasant shade for your guests on sunny days. However, a strong, unexpected wind can damage them beyond repair. By combining it with a wind sensor connected to the Shelly Plus AddOn, Shelly Plus 2PM can automatically close the outside awning to protect them from the wind. Additionally, Shelly Plus Add-on with a rain sensor can trigger Shelly Plus 2PM to open the awning just in time to protect your guests.
Shelly is an open platform. With the embedded web server and HTTP commands, Shelly can be made compatible with your home automation systems and projects… securely and easily.
