Measuring power consumption

All work on the electrical current (110V/220V) should be performed by a qualified technician.

Electricity meter

You may use 3 types of meters:

  • impulse counter
  • light/magnetic counter.
  • clamps

France only: recent power meters have a digital output called Teleinformation. This output is the official data, used by your energy supplier to bill you. There are several modules available to collect this data.

Private Counter

If your counter is on the road, you can install a meter on your private installation (or use a clamp meter, see below). A counter will have a private outlet: tele, light pulse or electrical impulse depending on the model.


A clamp meter to measure directly the phase of an electrical cable (to connect to use with caution).

There are power clamps (Aeon Labs Home Energy Meter, which is available with 1, 2 or 3 clips) such that allow the measurement up to several hundred amperes.

Light/magnetic pulse counter

There are 2 sensors from aeon labs: optical and magnetic.

Individual power consumption

Many switch (plug ON/OFF, ...) have an integrated meter, which allows the measuring of the consumption of the plugged equipments.

Connection of a water or gas meter

Light/magnetic pulse counter

There are 2 sensors from aeon labs: optical and magnetic.

Other pulse counter

To connect such a meter is to conduct two operations:

  1. Set up a pulse generator module
  2. Count the pulses and transfer them to the box eedomus.

The first point depends on your pulse counter. For Actaris-Itron, common in France, this module is called a "Cyble Sensor, 2 son." You can find it here: Cyble

The 2d point depends on the distance from the meter to the box eedomus, and technology radio or wire that can be used.

You can use a pulse counter ("Pulse Meter" in English). There are z-wave technology.

There are also pulse counters wired Ethernet, as IPX800-V3 (which allows multiple counts and shares). Using an Ethernet device is heavier in the installation (wiring), but significant for the use.
