Introduction

Read your Omnik solar inverter directly from your Homey, without a cloud account.

What the app does

  • Live monitoring - current power, today's production, lifetime kWh, AC voltage, grid frequency, and inverter temperature

  • Homey Energy integration - lifetime kWh feeds Insights and the Energy tab correctly

  • Flow automations - react when production starts or stops, or when output crosses a threshold

  • Two ways to read your inverter - direct binary protocol on TCP/8899 (preferred) or an HTTP fallback for inverters that don't support TCP

Supported hardware

The app talks to the WiFi module of your Omnik inverter - an external WiFi stick on most models, built into the inverter on TL2 and some others. Look at the sticker (on the stick if external, on the inverter if built-in) for the serial number; the first digits tell you whether it's likely to work:

WiFi-module serial number prefix
Status

160, 161, 604, 646

✅ Confirmed working

602606, 611/617, 504

⚠️ Same protocol family, likely works

601

❌ Cloud-only, no local API

Newer Solarman v5 / Ethernet sticks

❌ Different protocol - use the dedicated Solarman app

If your prefix isn't listed, the app will still try - it's not blocked. Pairing succeeds when your inverter actually responds.
