Hello everyone, I am trying to read out my Deye 12k permanently using this application. So far it works with my configuration. My data is read out and updated, but after about 20 minutes I keep getting timeouts until the data freezes. The log file outputs:

As the inverter is located in a wifi-free area, I have laid a network cable (CAT7) up to the meter cupboard (around 30 m). The CT is connected to 6 wires of the cable. On the remaining two wires I have branched off A and B from the ModBus port of my Deye, which go to a USB-to-RS485 adapter. I have already tried two different adapters and the same error pattern in each case. My battery is connected to the BMS port (also via RS485, CAN is only possible to a limited extent). I have the firmware C037 and 1144-1807 on it and also get data from the ModBus port. I also have the same problem when the battery is disconnected. My wifi dongle is not installed. The Deye is set to master and the Modbus SN is set to 01.

My config:
`DRIVER: pymodbus
INVERTERS:

SERIAL_NR: "*"
HA_PREFIX: SS
MODBUS_ID: 1
DONGLE_SERIAL_NUMBER: "0"
PORT: /dev/ttyUSB0

PROG_TIME_INTERVAL: 15
MQTT_HOST: core-mosquitto

The Output in MQTT is:

2025-02-02 13:23:04: New connection from 172.30.32.1:41259 on port 1883. 2025-02-02 13:23:04: New client connected from 172.30.32.1:41259 as 2yj9e3FMxADw8jbJ0SzxAZ (p2, c1, k60, u'*'). 2025-02-02 13:42:49: New connection from 172.30.33.1:48375 on port 1883. 2025-02-02 13:42:49: New client connected from 172.30.33.1:48375 as auto-D9BA70F1-08F2-8C43-5491-0E1EA2500D4D (p2, c1, k60, u'*'). 2025-02-02 13:52:15: Saving in-memory database to /data//mosquitto.db. 2025-02-02 14:12:27: Client auto-D9BA70F1-08F2-8C43-5491-0E1EA2500D4D closed its connection

For a possible Solution i changed to mbusd like recommended here: ( https://github.com/kellerza/sunsynk/discussions/98 )
With the following config:

DRIVER: pymodbus
INVERTERS:
  - SERIAL_NR: "*"
    HA_PREFIX: SS
    MODBUS_ID: 1
    DONGLE_SERIAL_NUMBER: "0"
    PORT: tcp://homeassistant.local:502`

Then I also get an EXCEPTION error after about 20-30 minutes:

Do you see a possible solution to prevent the timeouts? Have I overlooked a small detail in the configuration?

Thank you very much in advance

You can tune the schedule (you only need to read power every 5 seconds)

But the biggest change woudl probably be going via mbusd (not directly to the serial)

Thank you for the respond.
Which param do I have to change for that? I thought that I already changed it to 20 seconds.
And do you have a clue, what the Exception Error means, when I use mbusd?

These can be read once (or very infrequently

| 5  |                                  device_type                                   |
| 15 |                                serial, protocol                                |

Can probbaly tune them using these keys in the schedules

| date_time |     |  60  |   60   |           |          |    True    |
|     rw    |     |  5   |  300   |           |          |    True    |
|    enum   |     |  5   |  300   |           |          |    True    |

Thanks. I have changed the intervalls as following and using mbusd:

DRIVER: pymodbus
 INVERTERS:
  - SERIAL_NR: "**"
    HA_PREFIX: SS
    MODBUS_ID: 1
     DONGLE_SERIAL_NUMBER: "0"
     PORT: tcp://homeassistant.local:502`

Still getting the timeouts :

 OSError: OSError reading 1 registers from 590: failed to read register 590 - function code: 131; OSError reading 4 registers from 622: failed to read register 622 - function code: 131; OSError reading 4 registers from 633: failed to read register 633 - function code: 131; OSError reading 4 registers from 650: failed to read register 650 - function code: 131; OSError reading 4 registers from 672: failed to read register 672 - function code: 131 poll_need_to_read

The log of mbusd delivers:

10 Feb 2025 21:03:00 conn[172.30.33.1]: timeout, closing connection
10 Feb 2025 21:03:00 conn_close(): closing connection from 172.30.33.1
10 Feb 2025 21:03:00 conn_open(): accepting connection from 172.30.33.1
10 Feb 2025 21:03:40 conn[172.30.33.1]: timeout, closing connection

10 Feb 2025 21:03:40 conn_open(): accepting connection from 172.30.33.1

Do you have any further advice? Can it be a problem that my battery also uses RS485 at the BMS-Port while i am using the Modbus-Port?
