MQTT Bridge for Wallbox (Enhanced for EVCC)

This is a modified version of Fredrik Gustafssons awesome Wallbox Pulsar Plus mqtt bridge (https://github.com/jagheterfredrik/).

The changes here where made to use the mqtt bridge in conjunction with evcc (https://evcc.io).

To setup the Pulsar Plus with evcc follow the steps below:

1. Root your Wallbox and setup the bridge (see below)
2. Setup mqtt in evcc (https://docs.evcc.io/docs/reference/configuration/mqtt)
3. Extend the evcc configuration with following meter/charger/loadpoint (don't forget to replace the wallbox id placeholder)

meters:
- name: wallboxpulsarmeter
  type: custom
  power:
    source: mqtt
    topic: wallbox_<your_wallbox_id>/charging_power/state
    timeout: 180s
  currents:
    - source: mqtt
      topic: wallbox_<your_wallbox_id>/charging_current_l1/state
    - source: mqtt
      topic: wallbox_<your_wallbox_id>/charging_current_l2/state
    - source: mqtt
      topic: wallbox_<your_wallbox_id>/charging_current_l3/state

chargers:
- name: wallboxpulsarcharger
  type: custom
  status:
    source: mqtt
    topic: wallbox_147293/control_pilot/state
  enabled: # charger enabled state (true/false or 0/1)
    source: mqtt
    topic: wallbox_147293/charging_enable/state
  enable: # set charger enabled state (true/false or 0/1)
    source: mqtt
    topic: wallbox_147293/charging_enable/set
    payload: ${enable:%d}
  maxcurrent: # set charger max current (A)
    source: mqtt
    topic: wallbox_147293/max_charging_current/set


loadpoints:
- title: wallboxpulsar
  charger: wallboxpulsarcharger
  meter: wallboxpulsarmeter
  mode: pv

MQTT Bridge for Wallbox

This open-source project connects your Wallbox fully locally to Home Assistant, providing you with unparalleled speed and reliability.

Note: Doesn't work with firmware v6.6.x see issue jagheterfredrik#63

Features

• Instant Sensor Data: The Wallbox's internal state is polled every second and any updates are immediately pushed to the external MQTT broker.

• Instant Control: Quickly lock/unlock, pause/resume or change the max charging current, without involving the manufacturer's servers.

• Always available: As long as your local network is up and your Wallbox has power, you're in control! No need to rely on a third party to communicate with the device you own.

• Home Assistant MQTT Auto Discovery: Enjoy a hassle-free setup with Home Assistant MQTT Auto Discovery support. The integration effortlessly integrates with your existing Home Assistant environment.

Getting Started

1. Root your Wallbox
2. Setup an MQTT Broker, if you don't already have one. Here's an example installing it as a Home Assistant add-on
3. ssh to your Wallbox and run

curl -sSfL https://github.com/sweber/wallbox-mqtt-bridge/releases/download/v20241029_1/install.sh > install.sh && bash install.sh

Note: To upgrade to new version, simply run the command from step 3 again.
