[Bug]: Support for DYDA_WiBLE_1.6.2 firmware logger using UDP port 8899

[remalex123]

Environment

• Home Assistant Version: Latest (Docker container)
• Integration Version: Latest
• Logger Firmware: DYDA_WiBLE_1.6.2
• Inverter Model: DEYE SUN-8K-SG05LP1-EU-AM2-P

Problem Description

The logger with firmware DYDA_WiBLE_1.6.2 has TCP Modbus ports (8899, 10000, 502) completely blocked or disabled. Standard TCP connection attempts fail or time out (nc -zv 192.168.77.82 8899 times out).

However, checking port 8899 via UDP (nc -zuv 192.168.77.82 8899) confirms that the port is OPEN and responsive using standard Solarman V5 UDP frames.

Since the integration attempts to establish a TCP socket by default, it fails to connect to loggers running this specific DYDA_WiBLE firmware.

Proposed Solution / Feature Request

1. Add an option in the integration setup UI to select UDP as the transport protocol alongside TCP.
2. Ensure V5 Frame handling supports fallback or direct mode over UDP socket (SOCK_DGRAM) on port 8899.

Diagnostic Command Output

# TCP Check (Failed)
# nc -zv -w 3 192.168.77.82 8899 -> Connection timed out / blocked

# UDP Check (Success)
# nc -zuv -w 3 192.168.77.82 8899
192.168.77.82 (192.168.77.82:8899) open

Hello, I have the same model but the 5K version. I sent an email to Deye’s support team and they’ve updated the datalogger’s firmware to version DYDA_WiBLE_1.7.1.
Once it has been updated, enter the data logger’s IP address into your browser to access its settings, where you can enable a second connection with Modbus TCP access.

Hi! Thanks for your reply! Could you provide the email address where the message should be sent? Also, regarding the text of the email—I think it would be very useful and convenient for the community to simply copy and send it.

Hi, i sent email to service@deye.com.cn

English isn’t my first language, so some of my phrasing might not be quite right... 🫣

Hello! . 

I am writing to request an update for the data logger on the Deye inverter in my home.

I want to connect it to the Home Assistant home automation system and need a connection via Modbus TCP. I know this can be done via the Deye Cloud API, but it would overload the server with requests and, furthermore, the updates between states are very slow (taking minutes).

Whilst researching, I’ve read on forums that the new firmware version, DYDA_WiBLE_1.7.1, allows Modbus TCP access, which would be ideal. 

Please note, I only need to update the data logger; the inverter itself does not need updating. 

If you require any further clarification, please contact me at xxxx@xxxx

Data logger serial no.: XXXXXXX
Current firmware version: DYDA_WiBLE_1.6.2

Inverter serial no.: XXXXX

Thank you in advance. Best regards, 
Xxxx

They replied within a few hours, asking which country I was in, and by midday the following day I’d already received the update.
