Zigbee devices Smart plugs with energy metering

Nous D5Z

Zigbee smart energy meter with leakage and prepayment. Works with Zigbee2MQTT with no vendor hub or cloud: it pairs with a Zigbee stick and shows up in Home Assistant.

MQTT: state and commands

Zigbee2MQTT publishes the device state to zigbee2mqtt/my_device (my_device is the name you give the device). An example message:

{
  "state": "ON",
  "countdown": 43200,
  "power_on_behavior": "off",
  "status": "off",
  "power": 12.4,
  "current": 0.06,
  "voltage": 230,
  "energy": 3.21,
  "energy_produced": 0,
  "leakage_current": 0,
  "device_temperature": 31,
  "reclosing": false,
  "reclosing_delay": 50,
  "reclosing_count": 15,
  "linkquality": 120
}

Send commands to zigbee2mqtt/my_device/set:

mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"state":"TOGGLE"}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"power_on_behavior":"on"}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"reclosing":true}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"prepayment":true}'

Home Assistant automation example

Zigbee2MQTT creates Home Assistant entities from the device name. If it is called my_device, an automation in automations.yaml can look like this:

- alias: "Turn off when idle"
  mode: single
  triggers:
    - trigger: numeric_state
      entity_id: sensor.my_device_power
      below: 2
      for: "00:15:00"
  actions:
    - action: switch.turn_off
      target:
        entity_id: switch.my_device

Check the YAML: YAML checker.

How to pair it

  1. In Zigbee2MQTT click Permit join.
  2. Put the device in pairing mode: usually a long press of the reset button (5–10 s) until the LED blinks; bulbs: switch the power off and on 5–6 times.
  3. Keep the device close to the coordinator or a router while pairing.
  4. Give it a clear name: MQTT topics and Home Assistant entities are built from it.

Exact procedure and model notes: the device page in the Zigbee2MQTT docs. No coordinator yet: coordinator picker.
