Homey Pro (Early 2023) – Ethernet not working despite using official adapter

[Andries_de_Jonge]

Hi all,

I’m trying to connect my Homey Pro (Early 2023) via Ethernet using the official USB-C Ethernet adapter from Homey, following all instructions exactly as shown in the video provided by Athom.

Here’s what I did:

---

What I’ve tried

1. Connected the USB-C Ethernet adapter to Homey Pro, using:

   • the official Homey adapter
   • an active Ethernet cable (tested and confirmed working on laptop)
   • power supply via USB-C passthrough

2. Rebooted Homey multiple times (unplugged USB-C, waited, plugged back in).

3. Verified the Ethernet cable is live and plugged into a working switch port (UniFi).

4. Verified that the switch shows a physical link

5. Ran the Web API Playground using:

   (async () => {
     const info = await Homey.system.getInfo();
     console.log(JSON.stringify(info.ethernet, null, 2));
   })();

What’s not working

• ethernet.connected remains false in the API response.
• IP address is null, all Ethernet-related fields are null.
• Homey only reports being connected via Wi-Fi (wifiConnected: true).
• No output is shown in the Web API Playground console (a side issue — commands do execute, but no visible logs).

---

My question

What else can I do to get Homey to connect via Ethernet?

I’ve followed every step carefully:

• Cable and switch confirmed working.
• Adapter is official.
• followed several times this video and made sure I do it in correct order, https://support.homey.app/hc/en-us/articles/7262533910300-Setting-up-the-Homey-Pro-Ethernet-Adapter
• Reboot done in correct sequence (cable and power connected before powering on).
• Homey is running firmware version 12.4.8.

If helpful, I’m happy to record a short video showing the full setup.

Thanks in advance!

Just to double check: did you connect the adapter correctly? The long USB cable goes to your Homey, and the short to the power plug.

power supply via USB-C passthrough

For the long cable:
Try using a good quality USB data cable.
The quality of the one that came with Homey can be questionable.

Ethernet and Wifi the same network?

I can’t get it to work because Wifi is the IoT network of my Deco and the cable doesn’t.

whohhhhh..this did it. I took Apple USB-c cable and working..what a shit show.. anyway thanks for your help… I have another question but will create new post for this..I have now 2 devices appearing. trying to disable wifi by the WEB API Playground does not work

Oww that’s both good news, ánd sad to hear. If I’m informed right, you can request for a free replacement cable @ Athom support.

Wifi is used as fail-over: it is connected, but not actively used as soon as ethernet is successfully connected (as shown on your screenshot).
Of course you may disable wifi, but it shouldn’t be necessary.
