Changin Thermostat target temparature with Nextion up/down button

ESPHome
1

Hello everyone, if somebody can help me i am very apricated. I’m fighting with this proble almost five days. Here is the idea; I am making a thermostat with ESP8266 and Nextion display. I have two buttons (up and down) for changing the target temperature of the thermostat. I managed to print the thermostat target value on the screen, but I could not manage to change this value both on the screen and in the thermostat setting with the up and down buttons. Although many methods I tried compiles the codes without errors but they do not make any changes to the screen or the thermostat. The codes are as follows. I really need help.

Thank you.

                it.set_component_text_printf("page0.target_down", "%.1f", id(target_temp).state);
                call(climate.set_temperature);
            temperature: !lambda "return id(target_temp).state;"
     - logger.log: "Button down pressed"

Note: When I press the up and down buttons on the screen, “Button up pressed” and “Button down pressed” messages appear on the log screen.

I think this is more like it, but not sure how to do the lambda bit. This suggests a different config with data_template:

          service: climate.set_temperature
          target:
             entity_id: climate.kombi_thermostat
          data:
            lambda: |-
              id(target_temp).state = id(target_temp).state + '0.1';
              if id(target_temp).state > '30.0' { id(target_temp).state = '30.0'; }
              it.set_component_text_printf("page0.target_up", "%.1f", id(target_temp).state);
              call(climate.set_temperature);
            temperature: !lambda "return id(target_temp).state;

it says like this…

There are too many spaces indented in the line under target: (which is my fault).

Other than that this is exactly the yaml that HA creates when using the service internally, I thought it should be the same syntax in esphome

service: climate.set_temperature
data:
  temperature: 20
target:
  entity_id: climate.bedroom

It doesn’t work… :frowning_face:
