ALFA WHITE datalogger for 2.0 Open Meter wireless meters

ALFA is the first device that communicates with 2.0 Open Meter electricity meters. This allows you to control your energy consumption even more easily and accurately!

Before purchasing ALFA, verify that you have the new Open Meter 2.0 and download the free ALFA Tech app to check the service activation.

Device configuration requires the installation of the DU Connect smartphone app, which will allow you to set up access to your WiFi and activate the Chain2 service for your Open Meter 2G. ALFA is a device that, when plugged into any electrical outlet, can receive all information related to the served utility from the new generation electricity meter (Open Meter 2G). For the device to function correctly, the electricity meter in your home must be a new generation and support the Chain2 service for data transmission over power line. The DU Connect application will guide you through the request and activation of the service. Locally, via a LED bar and an acoustic alarm, it can provide qualitative information on the absorbed power and any imminent supply interruptions. If connected to WiFi, via the internet connection, all information received from the Open Meter 2G is transmitted to the cloud and accessed through the dedicated smartphone application.
