Adding your inverter

The pair flow is fully automatic in the common case - you only need the IP address of your inverter's WiFi module.

Step 1 - find the IP address

The WiFi module connects to your home network like any other device. Find its IP in:

• Your router's DHCP / "connected devices" page

• The Omnik app on your phone (if you set it up there originally)

• A network scanner like Fing

Tip: assign a fixed IP in your router so it doesn't change.

Step 2 - start pairing in Homey

In the Homey app: + Add device → Omnik → Omnik inverter.

Enter the IP and tap Next. The app then:

1. Reads /js/status.js from the inverter to discover the WiFi-module serial number automatically

2. Tries the binary TCP/8899 protocol with that serial number (preferred - it gives more data)

3. Falls back to HTTP for runtime data if TCP doesn't respond

4. Shows you the live readings on a confirmation screen so you can verify before adding

If the inverter web interface is password-protected

The factory default is admin / admin - both fields come pre-filled, just tap Continue. If those don't work the credentials have been changed at some point (rare); you'll need the values they were set to, or you can factory-reset the WiFi module to restore the defaults.

If auto-detect can't find your inverter

Some older firmwares don't have /js/status.js (you'd see a 404). The app then offers a manual S/N entry screen:

1. Find the sticker with the 10-digit serial number. On most models it's on the WiFi stick that plugs into the inverter - but the TL2 series and some others have the WiFi module built in, in which case the sticker is on the inverter itself.

2. The number usually starts with 160, 161, 604 or 646.

3. The app skips HTTP and tries TCP directly with that S/N.

After pairing

The device appears in your Homey with all capabilities. The first reading shows up within seconds; afterwards the app polls every 5 minutes by default. You can change the interval in Device settings → Check interval.
