Dimmerlink 4 channels incorrect value register 0x11 #5

It is connected to an ESP32, I am using ESPHome, and communication is via I2C. The code is as follows:

`
esphome:
name: esp01
friendly_name: ESP01
on_boot:
priority: -100
then:
- delay: 3s
- lambda: |-
// Sync curve ch1 on startup - Corrección de valor de fábrica
uint8_t reg = 0x11;
uint8_t curve = 0;
if (id(bus_a).write(${dimmerlink_addr}, &reg, 1, false) == i2c::ERROR_OK) {
if (id(bus_a).read(${dimmerlink_addr}, &curve, 1) == i2c::ERROR_OK) {

          auto call = id(dimming_curve_ch1).make_call();
          
          // Si el valor es correcto (0, 1 o 2), lo aplicamos normalmente
          if (curve == 0 || curve == 1 || curve == 2) {
            switch (curve) {
              case 0: call.set_option("LINEAR"); break;
              case 1: call.set_option("RMS"); break;
              case 2: call.set_option("LOG"); break;
            }
            call.perform();
            ESP_LOGI("dimmerlink", "Synced curve ch1: %d", curve);
          } 
          // Si lee un valor basura (como 50), forzamos el inicio en LINEAR (0)
          else {
            ESP_LOGW("dimmerlink", "Valor inválido detectado (%d). Forzando LINEAR (0) en Canal 1...", curve);
            call.set_option("LINEAR");
            call.perform(); // Esto activará el set_action de tu YAML y reescribirá el registro 0x11 con un 0
          }

        }
      }
  - delay: 100ms
  - lambda: |-
      // Sync curve ch2 on startup
      uint8_t reg = 0x13;
      uint8_t curve = 0;
      if (id(bus_a).write(${dimmerlink_addr}, &reg, 1, false) == i2c::ERROR_OK) {
        if (id(bus_a).read(${dimmerlink_addr}, &curve, 1) == i2c::ERROR_OK) {
          auto call = id(dimming_curve_ch2).make_call();
          switch (curve) {
            case 0: call.set_option("LINEAR"); break;
            case 1: call.set_option("RMS"); break;
            case 2: call.set_option("LOG"); break;
          }
          call.perform();
          ESP_LOGI("dimmerlink", "Synced curve ch2: %d", curve);
        }
      }

Register 0x13 works fine, but register 0x11 holds a value of 50, no matter how hard you try to write to it. This is my log:
