# Helium
Follow [the tutorial](https://docs.helium.com/use-the-network/console/quickstart) provided by Helium until you reach the heading "_Add a Device_".

For this step we need our `Dev EUI` (the LoPy4's MAC-address). We recieve this by running the following commands into the REPL terminal (or run it as a `main.py` file):

```python
>>> import binascii
>>> from network import LoRa
>>> print(binascii.hexlify(LoRa().mac()).upper())
```

Once we're finished setting up our Helium account and registering our device on the platform we can connect our device to the Helium LoRa network! Using the code provided by Pycom in [this tutorial](https://docs.pycom.io/tutorials/networks/lora/lorawan-otaa/#app) your LoPy4 should start connecting.
::: warning
❗Note: It can take a while to connect to Helium the first time.
:::
You'll see your device's connection trys on the Device page. (`Devices` > "Your device" > Scroll down to `Real Time Packets`).

With that you should be ready to use Helium as your platform as a LoRa connection!
