# 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                                   |
| `602`–`606`, `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.
