Euroster Smart - remote temperature control for your home. Euroster Smart is a new way of temperature control. Using a mobile application for iOS, we can control the operation of a heating or air conditioning unit from anywhere in the world with access to the Internet network. Depending on your needs, you can use the Euroster 4040 Smart battery-operated wireless radio or the 0101 Smart 230V powered. This application supports all Smart Series controllers. The Internet application controls the Euroster 4040 Smart wireless temperature controller. The controller communicates via radio waves with the receiver connected to the heating device. In practice, this means that you place the controller with a temperature sensor in a convenient place for you, without the hassle of installing a wired system. Two-way communication ensures stable operation and temperature control even if the Wi-Fi signal is lost. The Euroster Smart wireless controller consists of only 2 parts - a temperature controller placed in the place of temperature measurement (room, kitchen, etc.) and a receiver with a radio and Wi-Fi module connected to the heating/air conditioning device. Euroster 0101 Smart is a controller that requires 230V power supply connected by wire to the controlled device. The temperature is regulated according to the indications of the sensor placed in the regulator. The controller does not require any additional accessories - the WiFi module is placed inside the device. The application allows you to control most of the functions available in the regulators, and the weekly programming of temperatures and hourly intervals is simplified to a minimum. Any change made manually in the controller will be visible in your app. The app supports up to 6 Euroster Smart Sets, each of which can be given an individual name. The app requires you to create an account with a password to access it.
