Specifications

The 412015 is Legrand's connected single-phase energy meter in the Drivia with Netatmo range. It is one DIN module (17.7 mm) wide and comes with a closed current transformer rated 80 A AC on an 800 mm lead that clips into the module. The transformer takes one conductor of 10 to 25 mm², or up to eight 1.5 mm² conductors, so one meter can cover a single circuit or a whole supply.^2, 3

Power

Mains. Powered at 100 to 240 V AC from the single-phase line, through its own C2 to C16 breaker, 0.3 W maximum.²

Maximum current

80 A AC, closed current transformer²

Accuracy

±1 % for module and transformer, above 2 A and cos φ ≥ 0.8²

Accuracy class

Where it is used

• Power on one single-phase circuit up to 80 A, such as a water heater, heat pump or kitchen circuit, from the distribution board.

  HVAC energy monitoring for commercial buildings

• Solar production on a single-phase inverter line, paired with a second meter for consumption.

  Solar PV monitoring

• Total power at a small single-phase supply, with several conductors through one transformer.

  Multi-site energy monitoring

Interface

Readings and settings, with units and ranges where Legrand publishes them. R readable, R·W readable and writable.^5, 6

Zigbee2MQTT's documentation notes that this module might only work on Zigbee channel 11. Once the network runs on channel 11 and is open for joining, a module showing a steady red LED joins by itself.⁴

It reads through the Electrical Measurement cluster: active power in W and apparent power in VA. It does not report an energy counter over Zigbee; Legrand's app keeps the consumption history.^2, 5

The power alarm uses Legrand-specific attributes in the same cluster: an enable flag, a threshold and an active flag. Zigbee2MQTT's converter also reads the threshold, which it names power_alarm_wh_threshold.⁶

The module forgets its reporting configuration after a restart or power loss. Zigbee2MQTT's definition sets reporting up again each time the module announces itself on the network.⁵

Setup

1. Wire the module with the supply off

   Turn off the main breaker. Connect L and N through a C2 to C16 breaker and clip the current transformer's connector into the module.²

2. Fit the current transformer

   Pass the conductors of the circuit or supply through the transformer with the arrow in the direction of current flow. For solar production, place it strictly upstream of the production section.³

3. Clear any earlier pairing

   If the module has been used before, hold its configuration button for more than 5 seconds until the LED turns steady red. It is then no longer associated with any gateway.²

4. Open pairing in Edge and switch on

   Open pairing on the Gateway's Zigbee network in Edge, refit the front plate and turn the main breaker on. The LED is steady red until the module joins, steady green once it has joined while the network is still open, and off in normal use.²

5. If it does not join

   Zigbee2MQTT's documentation notes that this module might only work on channel 11. Check which channel the Gateway's Zigbee network uses before you try again.⁴

6. Check one reading

   Run a known load and compare active power with a clamp meter. A negative value on a consuming load means the transformer is the wrong way round.

Common questions

Why does the 412015 not join my Zigbee network?

Zigbee2MQTT's documentation notes that it might only work on Zigbee channel 11. Also check that it has been reset: a steady red LED means it is not paired and ready to join.^2, 4

Does it report energy in kWh over Zigbee?

No. Its Zigbee definition reports active power, apparent power and a power alarm. Energy history is kept by Legrand's app.^2, 5

Can it measure solar production?

Yes, with the transformer strictly upstream of the production section. Legrand then requires a second meter or a connected load shedder for consumption, and the arrangement is not compatible with a connected ecometer or storage batteries.^2, 3

Can it be used on a three-phase supply?

No. Legrand states it is not compatible with a three-phase installation. The three-phase version is the 412175.¹
