Intelligent hardware and software for

tenant electricity models

We supply you with intelligent hardware and software for measuring, visualising, billing and controlling the energy flows in your tenant electricity system. Our complete system can be easily and inexpensively installed in new systems or retrofitted to existing buildings. Our devices are compatible with various open interfaces, such as MSCONS API, ...

With our ntelligent hardware and software  you can optimise your own consumption of your PV system. Smart-Red offers you an automatically generated, multi-tariff capable billing.

Tenant electricity brings advantages for all!

There is nothing better than this: Provide your tenants with the electricity of your own photovoltaic system! Now you are independant of the public grid - make your own eco-friendly electricity! Photovoltaic systems, heat pumps or cogeneration units provide all tenants with their own eco-friendly electricity - that's tenant electricity!​
Electricity can be produced and used on site, without purchasing power from the public grid.
For the tenants electricity is becoming less expensive & landlords can upgrade their property and can profit from self-produced electricity.

Tenant electricity - how it works

Photovoltaic systems, heat pumps or cogeneration units produce electricity on site.

This electricity is fed directly into the in-house grid to provide the tenants.

Any electricity that is not required, can be saved in battery storage or fed into the public grid.

Photovoltaic system

public grid




produce 0.074 kW

submit 0.009 kW

require 0.065 kW

100 % of the electricity demand is covered by self produced electricity.

The surplus is fed into the public grid.

Measurement concept

In the case of a simple household consumption community, all consumers (each apartment and general electricity) are measured separately with one meter. Also all producers (solar system, battery storage) are measured with one meter each. Ideally, the smart-me 3-phase meter is used for this. You can find more smart-me meters here

Measurement of energy data with intelligent hardware

Current by direct measurement or modules

M-Bus data for heat, water and gas

Visualizations, optimizations and accounting can be created in the web portal

Data is always available via app and web portal (Authorization, PIN authorization, SMS authorization, online billing module)
