Introduction
Wi-Fi thermostat-weather station MST-91Ai (hereinafter referred to as the weather station) is
designed to control cable anti-icing systems for roofs, open areas, pipelines, and tanks, as well as
any other cable systems for electrical heating.
The weather station was designed using dual-core microprocessor technology using the RTOS
(real-time operating system), which made it possible producing an exceptionally reliable snow
melting system. Using several unique settings and algorithms, our own weather service and
technology for remote access to weather station sensor data, we have created a flexible and
economical next-gen snow melting system.
The weather station has one channel (1 control relay) and can control one heating system.
The weather station supports the following types of sensors:
Sensor type
Name (Article)
Abbreviation
Temperature / surface sensor
Grand Meyer TS-1
TS
Moisture and precipitation sensor
Grand Meyer TS-2
MPS
The weather station can work fully autonomously with the Internet weather service (no sensors
required or using weather service data when sensors are disconnected/unavailable).
The weather station is configured and managed via the integrated web interface.
This interface allows customers to remotely access all the functions and settings of the system. It
is also allowed connecting the weather station to the Telegram messenger for real-time alerts on
various events and control of the weather station (turning the heating section on and off, etc.).
