Serial number not displaying correctly

[ameran]

Hi,

When copying the code to create an entity for serial number, when I use this code:

• platform: modbus_controller # 003-007 Inverter HEX Serial Number modbus_controller_id: inverter id: inverter_esphome_serial register_type: holding skip_updates: ${settings_skipped_updates} raw_encode: HEXBYTES address: 003 register_count: 5 internal: true

• platform: template # Inverter ASCII Serial Number name: "${friendly_name} Serial" id: inverter_esphome_ascii_serial icon: "mdi:text" lambda: |- std::string hexData = id(inverter_esphome_serial).state;

  // Convert hex-encoded string to ASCII std::string asciiData; for (size_t i = 0; i < hexData.length(); i += 2) { std::string byte = hexData.substr(i, 2); char chr = static_cast(std::stoi(byte, nullptr, 16)); asciiData.push_back(chr); }

  return asciiData;

mine only displays a single registers value. Its like its not combining the registers, is there something I'm doing wrong?

@ameran thanks for reporting. I was missing the response_size when reading the registers. See updated code below

  - platform: modbus_controller            # 003-007 Inverter HEX Serial Number
    modbus_controller_id: inverter
    id: inverter_esphome_serial
    register_type: holding
    skip_updates: ${settings_skipped_updates}
    raw_encode: HEXBYTES
    address: 003
    register_count: 5
    response_size: 9
    internal: true

Awesome! It's working perfectly!

Quick note, this line should be: response_size: 10 that one then matches whats on the display.

Thanks also realized this.
