Landis+Gyr Module

Sales discontinued on 30.04.2021, support and cloud support guaranteed until 30.03.2025.

The Landis+Gyr module brings the measurement data of the L+G E450 and E350 energy meters into the smart-me Cloud.

The module does not require any additional hardware. It uses the existing WiFi network and connects directly to the smart-me Cloud. This is the easiest way to analyze and optimize energy consumption in real time on your smartphone, tablet or computer.

With a Professional subscription, the meter values can also be queried via the Modbus TCP interface.

Successor product

smart-me does not offer a successor product for L&G meters.

If you operate a smart-me ZEV (association for own consumption) and need a new solution for your metering (e.g. HAK), the L&G module must be replaced by a Telstar 80A or Telstar CT.

If measurements are carried out in a private setting for monitoring, home automation, etc., the Telstar 80A or Telstar CT can be installed at any time. If you are looking for a solution with your existing L&G meter, we recommend taking a look at this page. https://gplug.ch/
