rainSensor is a rain sensor that allows you to detect the moment when it started raining and the moment when it stopped raining.

This allows not only to detect rain, but also to determine the time for which it rained.

Chart and historical data

An interactive chart and annual history of measurements will allow you to check when the last rain occurred, and thanks to remote access you can check if it is raining, even if you are not at home.

The data can also be exported to a file for further processing


Unexpected rain will never surprise you again. Thanks to the notification about the beginning of rain, you will always have time to hide your laundry or protect sensitive belongings.

Windows Automation

The rainSensor sensor after detecting rainfall can wirelessly send a command to as many as 30 other BleBox devices.

In conjunction with the shutterBox controller, automatically close the roof windows.

Watering automation

In combination with the switchBoxDC controller, turn off the solenoid valves so as not to water the garden during rain!


An additional, logical, wired output allows the rainSensor to be connected to other elements or building automation systems that do not have WiFi wireless connectivity (e.g. watering systems, roof window control systems)
