<!--
The Homebridge Raspberry Pi image is just Raspbian Linux with Homebridge installed as a service.
If you are facing an issue that is not Homebridge related you should look elsewhere for support.

**Describe The Bug:**
I have a hidden network, so that when configuring the Homebridge on my Raspberry device, I cannot see listed my network on the list, because it is hidden and there is no option to select other networks or set the SSID of the network to connect with.

To solve this issue, I need to make my network broadcast the SSID to connect the Homebridge to my network.

Would be posible to add the option to select hidden networks?

**To Reproduce:**
Just disable the option to broadcast the SSID to make your network not visible, and the Homebridge will not connect.

**Expected behavior:**
When configuring the wireless network is supposed to have an option to select other networks or a field to input the SSID if not found.
