# Quick Fix: "Controller ID not exist" Error

## The Problem

You're seeing:
```
Omada login failed: Controller ID not exist.
```

This means you're using the **wrong value** for `omadac_id`.

## The Solution (5 minutes)

### Step 1: Get the Real Customer ID

1. Open your Omada controller UI (Cloud-Based Controller)
2. Go to **Settings → Platform Integration → Open API**
3. Find your app: **Datacenter-Control-Complete**
4. Click **View / Details**

On that page, you'll see:
- **Client ID** → This goes in `OMADA_CLIENT_ID`
- **Client Secret** → This goes in `OMADA_CLIENT_SECRET`
- **Customer ID / MSP ID / Omadac ID** → This goes in `OMADA_CUSTOMER_ID` ⚠️ **This is the one you need!**

### Step 2: Update Your `.env` File

Replace your current values with:

```env
# From OpenAPI page - Client ID
OMADA_CLIENT_ID=<Client ID from Open API page>

# From OpenAPI page - Client Secret
OMADA_CLIENT_SECRET=<Client Secret from Open API page>

# From OpenAPI page - Customer/MSP ID (THIS IS THE KEY ONE!)
OMADA_CUSTOMER_ID=<Customer/MSP/omadac id from Open API page>

# Your Omada credentials
OMADA_USERNAME=teresa@teresalopez.us
OMADA_PASSWORD=L@kers2010

# Your Omada endpoints
OMADA_NORTHBOUND_BASE=https://euw1-omada-northbound.tplinkcloud.com
OMADA_CONTROLLER_BASE=https://euw1-omada-controller.tplinkcloud.com

# Use password auth to avoid OAuth noise
OMADA_AUTH_METHOD=password
```

### Step 3: Restart

```bash
pnpm run dev
```

## What You Should See

After updating `OMADA_CUSTOMER_ID`:

✅ **Success**: `Omada login successful`

OR

✅ **Progress**: `Omada login failed: Invalid username or password` 
   (This means the Customer ID is correct! Just fix your username/password.)

## Important Notes

- **DO NOT** use `TP_LINK_CLIENT_ID` value as `OMADA_CUSTOMER_ID` - they're different!
- The `OMADA_CUSTOMER_ID` is the **controller/customer ID**, not the application client ID
- If you're using an MSP account, look for "MSP ID" instead of "Customer ID"

## Still Having Issues?

If you still see "Controller ID not exist" after updating:
1. Double-check you copied the **exact value** from the OpenAPI page
2. Make sure there are no extra spaces or characters
3. Verify you're looking at the correct application in the OpenAPI settings
