The weather station was produced using dual-core microprocessor technology on the real-time operating system RTOS, which made it possible to build a very reliable snowmelt system.

The use of a number of unique settings and algorithms, our own weather service and the technology of remote sharing of sensors between weather stations made it possible to create a flexible and cost-effective new generation snowmelt system.

The weather station is configured and controlled through the built-in web interface, which ensures its correct and convenient display on devices with different screen resolutions, both on a mobile phone and a computer.

Supported browsers: Chrome, Opera, Firefox, Safari, IE, EDGE. It is also possible to connect the weather station to the Telegram messenger for real-time notification of various events in the management of the weather station (turning on, turning off heating zones, etc.).

The weather station can operate in fully automatic mode via the Internet weather service (without the use of sensors or use weather service data when they are turned off).

The weather station supports the following types of sensors:

Installing the weather station

The weather station is mounted on a DIN rail; for this, special latches are provided on the back cover of the case. The heating sections of the heating system are connected after their installation and testing. The power supply of the weather station is connected through a circuit breaker after checking all connections. After power is applied, the red LED P should light up.
