Messaging via Home Assistant webhook-trigger and shoutrrr -without cloud-

[thecem]

EVCC is able to send the messages via shoutrrr direct to Home Assistant.
HA will be triggered via Webhock-trigger and send the notify vie Home Assistant Companion App, so no cloud service is needed!

1. Configure the HA Automation:

• Create a new automation via UI, select Webhook as the Trigger. Home Assistant will automatically assign it a unique ID.
• Switch to YAML-Mode and attach following snipplet.
• Hit save and give it a good name.

add snipplet to automation in YAML mode

replace:

action: []

with:

action:
  - metadata: {}
    data:
      title: ev⚡️cc
      message: "{{ trigger.json.message }}"
      data:
        subtitle: "{{ trigger.json.title }}"
        url: /49686a9f_evcc
        push:
          badge: 1
    enabled: true
    action: notify.notify
mode: single

2. Configure evcc:

add snipplet to evcc.yaml (optimised for IOS)
