Sending MeshCore Messages to Discord via Home Assistant

This guide explains how to forward MeshCore messages into Discord using Home Assistant as the bridge. You’ll need the MeshCore-HA integration (installed via HACS), and Home Assistant’s built-in Discord integration.

Prerequisites

• A working Home Assistant setup
• HACS installed and configured
• Discord webhook or bot token ready
• A configured MeshCore node

Steps

1. Setup MeshCore-HA

• Open HACS in Home Assistant
• Search for MeshCore-HA
• Install the integration and restart Home Assistant
• Configure the integration by adding your MeshCore node details in Home Assistant

2. Add the Discord Integration

• In Home Assistant, go to Devices & Services
• Click Add Integration
• Search for and select Discord
• Request the API token from MrAlderson
• Enter the token and click Submit

3. Add the Testing Channel to the HA Companion

• Disconnect MeshCore-HA from your Companion device
• If using Wi‑Fi: connect to your Companion via the MeshCore mobile app
• If using USB: connect to your PC and open [[1](https://app.meshcore.nz) app.meshcore.nz]

 Click Connect → the 3‑dot menu → Connect via USB

• Once connected, join the Testing channel just like you would in the mobile app
• When finished, disconnect and reconnect to Home Assistant

4. Verify the Channel Number

• Determine which channel number corresponds to Testing (likely Channel 2).
• In Home Assistant, navigate to: Devices → MeshCore → your Companion node
• From your mobile device, send a message to the Testing channel
• Check the Status page in Home Assistant — the message should appear under Channel 0 or Channel 1

5. Create an Automation to Forward #testing to Discord

• In Home Assistant, go to Settings → Automations & Scenes → Automations
• Click New Automation
• Open the 3‑dot menu (top right) → Edit in YAML
• Paste the YAML below and Save

alias: MeshCore - Bot - Forward testing to discord
description: When Testing receives a message forward it to Discord
triggers:
  - event_type: meshcore_message
    event_data:
      message_type: channel
      channel_idx: 1
    trigger: event
    enabled: true
conditions: []
actions:
  - action: notify.benderha
    metadata: {}
    data:
      target:
        - "DISCORD-THREAD-ID"
      message: "{{ trigger.event.data.sender_name }}: {{ trigger.event.data.message }}"
mode: parallel
max: 20

Replace values

• DISCORD-THREAD-ID → Request the thread ID from MrAlders0n and replace it in the YAML.
• channel_idx: 1 → Replace with the channel number for Testing that you discovered in Step 4.
