No data connection on port 502 with Deye SUN-6K-SG05LP1-EU AM2 P (Firmware DYDA_WiBLE_1.7.2)

[thecifu]

Hi everyone / Developer,

I am having trouble getting any data from my Deye inverter using this integration. All entities remain as "Unavailable" (No disponible) in Home Assistant.

Here are my specific hardware and configuration details:

Environment Details

• Inverter Model: Deye SUN-6K-SG05LP1-EU (Single-phase hybrid)
• Logger Firmware Version: DYDA_WiBLE_1.7.2
• Integration Configuration:
  • Host IP: 192.168.1.151 (Static IP)
  • Port: 502
  • Inverter ID / Slave ID: 1
  • Lookup File: deye_hybrid.yaml (Also tested deye_sg04lp3.yaml initially)

Context & Steps Already Taken

Due to recent Deye firmware security changes in the 1.7.x branch (where the traditional local port 8899 is blocked), I have manually enabled the native Modbus TCP feature on the logger's local web interface:

1. Link2 Configuration: I have explicitly enabled Link2 on the logger, selecting Modbus TCP protocol on Port 502. Link1 remains untouched on default (Deye MQTTS).
2. Integration Clean Install: I completely removed the Solarman integration from Home Assistant, restarted the system, and did a fresh setup directly specifying Port 502 and the deye_hybrid.yaml definition file.

Despite the logger's Link2 being properly saved and active on port 502, the integration is still unable to fetch or populate any sensor data.

My Questions

• Does this specific component version fully support the pure Modbus TCP connection (mbtcp) required by the newer 1.7.2 firmwares when using port 502?
• Is there any hidden parameter or specific tweak I should apply to the deye_hybrid.yaml file (such as forcing a specific parser or connection type) to make it work under this firmware setup?

Any guidance or diagnostic steps would be highly appreciated. Thank you so much for your amazing work on this integration!

Update & Solution

I managed to completely resolve the issue.

The problem was not with the Deye logger or its Modbus TCP configuration on Port 502 (the Link2 settings were perfectly fine). Instead, the issue stems from an incompatibility between recent Home Assistant/Python updates and the codebase of this specific, archived repository. It triggers severe asynchronous blocking errors and internal exceptions (KeyError: 'requests').

How to fix this for anyone facing the same issue:

1. Remove this old Solarman integration from your Home Assistant setup.
2. Open HACS -> click the three dots in the top right -> select Custom repositories.
3. Add the active, modernized fork maintained by David Rapan: https://github.com (Select Integration as the category).
4. Download and install Solarman Stick Logger from HACS.
5. Restart Home Assistant.
6. Set up the integration again using your local Deye IP, Port 502, and select deye_hybrid.yaml.

It will connect instantly and natively via pure Modbus TCP without any errors. I am closing this discussion as resolved!
