Hey, first of all thanks for working on that!
I've tried to migrate over by changing

includes:
     - templates/Foxess-T-series-ESPHome-Home-Assistant/foxess_t_series.h

from this repo to

external_components:
  - source:
      type: git
      url: https://github.com/SibrenVasse/Foxess-T-series-ESPHome-Home-Assistant    

shown in your example yaml.

Unfortunately it spawned this error at compile time:

/config/foxess-inverter.yaml: In lambda function:
/config/foxess-inverter.yaml:122:32: error: expected type-specifier before 'foxesscomponent'
     auto foxesssensors = new foxesscomponent(id(uart_bus));
                                ^~~~~~~~~~~~~~~
/config/foxess-inverter.yaml:158:7: error: could not convert '{<expression error>, <expression error>, <expression error>, <expression error>, <expression error>, <expression error>, <expression error>, <expression error>, <expression error>, <expression error>, <expression error>, <expression error>, <expression error>, <expression error>, <expression error>, <expression error>, <expression error>, <expression error>, <expression error>, <expression error>, <expression error>, <expression error>, <expression error>, <expression error>, <expression error>, <expression error>, <expression error>, <expression error>, <expression error>, <expression error>, <expression error>, <expression error>, <expression error>}' from '<brace-enclosed initializer list>' to 'std::vector<esphome::sensor::Sensor*>'
     };
       ^

which seem to be related to lambda function from https://github.com/assembly12/Foxess-T-series-ESPHome-Home-Assistant/blob/main/foxess-inverter.yaml (line 61-100 here).

Is there any way to cleanly replace that? I've seen your https://github.com/SibrenVasse/Foxess-T-series-ESPHome-Home-Assistant/blob/main/foxess-inverter.yaml.example, but I'm afraid it would completely replace my entity names and anything depending on them in the process.

[SibrenVasse]

You have to replace everything below the 'uart:' section with the sections from the new yaml example.

If you're worried about entities changing name in Home Asisstant, you have to make sure the new sensor has the same 'name' field in the yaml file. Like this:

button:
  - platform: restart
    name: "Foxess inverter restart"

text_sensor:

    grid_power:

                id(inverter_mode_text_sensor).publish_state("Offline");
              } else if (x==1) {

              } else if (x==2) {
                id(inverter_mode_text_sensor).publish_state("Error");
              } else {
                id(inverter_mode_text_sensor).publish_state("Waiting for response...");
              }

You have to replace everything below the 'uart:' section with the sections from the new yaml example.

If you're worried about entities changing name in Home Asisstant, you have to make sure the new sensor has the same 'name' field in the yaml file.

thanks for adapting it for me, that helped me a lot!

I've adapted it further to work with LilyGo T-CAN485 board I'm using (works great with no need to add voltage controllers or RS485 components):

# Set pins required for LilyGo T-CAN485 board
output:
  - platform: gpio
    id: ENABLE_PIN # Enable the chip
    pin:
      number: GPIO19
      inverted: true
  - platform: gpio
    id: SE_PIN # Enable autodirection
    pin:
      number: GPIO17
      inverted: true
      allow_other_uses: true
  - platform: gpio
    id: ENABLE_5V_PIN # Enable 5V pin for RS485 chip
    pin:
      number: GPIO16
      inverted: true

# Configure uart that will be used
uart:
  id: uart_bus
  rx_pin: GPIO21
  tx_pin: GPIO22
  baud_rate: 9600
  # debug:

I have an optional light section for control over the built in LED:

light:
  - platform: esp32_rmt_led_strip
    id: led_light
    name: "${friendly_name} Light"
    pin:
      number: GPIO04
    num_leds: 1
    rmt_channel: 0
    rgb_order: GRB
    chipset: ws2812

which I'm using to show different color depending on energy production:

generation_power:
    name: "T-Series Generation Power"
    on_value_range:
    - below: 1.0
      then:
        - light.turn_on:
            id: led_light
            red: "100%"
            green: 0
            blue: 0
    - above: 1.0
      below: 1000.0
      then:
        - light.turn_on:
            id: led_light
            red: "100%"
            green: "100%"
            blue: 0
    - above: 1000.0
      below: 2000.0
      then:
        - light.turn_on:
            id: led_light
            red: 0
            green: 0
            blue: "100%"
    - above: 2000.0
      then:
        - light.turn_on:
            id: led_light
            red: 0
            green: "100%"
            blue: 0

I had to add configuration for flow control pin, it seems to be GPIO17 on that board:

flow_control_pin:
    number: GPIO17
    inverted: true
    allow_other_uses: true

@SibrenVasse for some reason your version fails to update some of the sensors, while the version from this repo does. I've noticed my Foxess Inverter T-Series Today Yield (and Total) was updating very infrequently (less often than once an hour) messing up my statistics.

Can you upload your yaml file? So I can check that everything is the same in my environment.

Here's the config I'm using. The commented out part is the 100% working code from here. The uncommented is derived from yours that fails to process part of the message received from Foxess inverter.

Somehow it's only publishing the sensor states until line foxess_solar.cpp#L156

Do you have a log snippet for when it does update the sensors after line 156? Did you capture the logs via the network?

Can you try this instead of the external_component in your config?

The [FoxessSolar::parse_message:126]: Unexpected msg length, length: 165 says that it failed to parse the message (which the implementation you forked from has no issues with), which is why it doesn't show some of the properties.

[SibrenVasse]

It's just a message to warn that the length of the messages received by the inverter are valid (integrity checked by checksum, which the original implementation does not do), but not the same length as the messages I verified my code with. here
It will not abort parsing the message, just print the warning to the logs.

The parsing itself has not changed from the original code.

Ok. Something has though as it seems to cut off data received from the inverter with your code, cause it works with the original. Anything else I can check?

Here's what the original code outputs:

I don't know how much you have changed, or if it matters but when I compiled the original version with ESP-IDF 5.3.1 it was erroring out with src/foxess_t_series.h:351:30: error: format '%i' expects argument of type 'int', but argument 5 has type 'uint32_t' {aka 'long unsigned int'} [-Werror=format=]. I know it is just a warning treated as error, but you must have changed something here (validating/converting types?) since your code does compile with it.
