Landis+Gyr Module

The smart-me module integrates the measured data of the energy meters L+G E450 and E350 into the smart-me cloud. No additional hardware is needed. The module uses the existing Wi-Fi network and connects directly with the smart-me cloud. This is the easiest option to analyse and optimise the consumption of energy with the help of a smartphone, a tablet or a computer in real time.


  • Real time visualisation of power, accumulated meter reading (purchase and supply), tariffs 1 and 2 reactive power and reactive energy

  • Automatic storage of meter readings in the cloud

  • Storage and automatic synchronisation of measurement data in case of connection failures to the cloud

  • Encrypted Wi-Fi connection directly to the smart-me cloud

  • Contact output to control external devices

  • The smart-me cloud enables extensive energy data management, automatic invoicing, remote controlling and alarms

  • Easy installation using the free smart-me app available for Android and iOS

Video Installation

The battery can be removed after installation because the module is fed by the meter.
