Homewizard kWh meter installation

[caveman85]

Is there anyone who can provide some more (installation) details on how to get the HomeWizard-kWh-MQTT-bridge up and running on a ESP01 device? And how to connect it to P1P2 bridge

If you are running Home Assistant, you do not need the ESP01 device. Instead, you can set up the HomeWizard integration in HA and add to the yaml configurations in HA:

- id: '999999999'
  alias: output kWh meter via MQTT
  triggers:
  - entity_id: sensor.kwh_meter_power
    trigger: state
  - trigger: time_pattern
    seconds: '0'
  actions:
  - data:
      topic: P1P2/P/meter/U/9/Electricity_Power
      payload: '{{ states(''sensor.kwh_meter_power'') }}'
    action: mqtt.publish

If you do not use HA but use an ESP01, you can program the ESP01 via a USB programmer with the instructions in the Firmware README.
