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:
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.
