# 🤖🤖🤖 Multiple Devices

> Connect multiple Elato Devices to your network

1. Register your device by adding your ESP32 Device's MAC Address and a unique user code to the `devices` table in Supabase.

<Tip>
  **Pro Tip:** To find your ESP32-S3 Device's MAC Address, build and upload `test/print_mac_address_test.cpp` using PlatformIO and view the serial monitor.
</Tip>

2. Register your user account to this device by adding your unique user code to the [Settings page](http://localhost:3000/home/settings) in the NextJS Frontend. This links your device to your account.

3. Set DEV\_MODE to `False` in your `frontend-nextjs/.env.local` env variable.

<Tip>
  **Pro Tip:** If you're testing locally, you can keep enabled the `DEV_MODE` macro in the `Config.h` file of your firmware and the Deno server env variable to use your local IP addresses for testing.
</Tip>

4. Now you can register multiple devices to your account by repeating the process above.
