## 👥 Configuration & Profiles

Add your WhatsApp accounts via the Home Assistant UI:
1. Go to **Settings** -> **Devices & Services**.
2. Click **Add Integration** and search for **WhatsApp Bridge**.
3. Follow the setup to add an **Account Name** (e.g., "Work") and your **Phone Number**.
4. **Repeat** this process for as many accounts as you need.

### Resulting Entities
The integration automatically creates sensors for your UI:
* `sensor.whatsapp_account_name`: An entity for each individual account.
* `sensor.whatsapp_broadcast_all`: A global entity to message all accounts at once.

## 🛠 Usage

### Action: `send_message`
This integration registers a service/action to send messages.

**Fields:**
* **Recipient:** Select an account from the dropdown, choose the "Broadcast" entity, or manually type a phone number.
* **Message:** The text content you wish to send.

#### YAML Example:
```yaml
action: whatsapp_bridge_integration.send_message
data:
  recipient: "sensor.whatsapp_rene"
  message: "The garage door is still open!"
```

## ⚠️ Important Notes
Phone Numbers: Always use the international format without + or 00 (e.g., 49... for Germany).

Local Network: The integration communicates locally with the Add-on on port 3000.

## 🤖 Node-RED Integration
The integration is fully compatible with Node-RED. Since it uses native entities, you can use the standard *Action (Call Service)* node.

### Example: Smart Window Warning
Notify yourself if a window or door has been left open for 15 minutes.

 1. *Trigger*: Use a `State Trigger` or `Device` node.

 2. *Logic (Change Node)*: Use JSONata to create a dynamic message:

  - *Set*: msg.payload

  - *Value (JSONata)*: `payload.to_state.attributes.friendly_name & " has been open for 15 minutes!"`

 3. WhatsApp Node (Action Node):

  - *Action*: `whatsapp_bridge_integration.send_message`

  - *Data (JSON)*:

```JSON
{
   "recipient": "sensor.whatsapp_broadcast_all",
   "message": "{{payload}}"
}
```

### Manual Tool Calling
To send a message to a number not saved as a profile, simply pass the raw phone number to the recipient field in your Node-RED JSON:

```JSON
{
  "recipient": "491701234567",
  "message": "Direct alert to external number."
}
```
