Hello Every One and best wishes for 2022
I try to upadte my time on my NSPAnel But if the time and date is correct when the Nspanel boot
The values (Time and date) don’t update
The values of CO2 sensor and temperature from home assistant update
Can you check my Code and help me ?
Thanks

In the same scope i try to print the sunset time and sunrise time
I add

sun:
  latitude: 48.8584°
  longitude: 2.2945°
text_sensor:
  - platform: sun
    name: sunrise
    id: sunrise
    type: sunrise
    format: ("%H:%M")
  - platform: sun
    name: sunset
    type: sunset
    id: sunset 
    format: ("%H:%M")

In the code but i cant find how to print it !!!

For the sunset and sunrise i find this solution

text_sensor:

  - platform: homeassistant
    id: sunrise
    entity_id: sensor.sunrise_time 
    on_value:
       then:
         - lambda: 'id(disp1).set_component_text_printf("sunrise","%s",id(sunrise).state.c_str());'    
  - platform: homeassistant
    id: sunset
    entity_id: sensor.sunset_time 
    on_value:
       then:
         - lambda: 'id(disp1).set_component_text_printf("sunset","%s",id(sunset).state.c_str());'

and in display i have add after lambda

            id(disp1).set_component_text_printf("sunrise","%s",id(sunrise).state.c_str());
            id(disp1).set_component_text_printf("sunset","%s",id(sunset).state.c_str());

Hello!

I don’t use the same approach as you do, I use HomeAssistant time, not SNTP time, but for what its worth, here is “my” config, which (finally works). I need to credit @masto for 98% of the config here…

Hi, on the last one with HA time, this makes my device reconnect every 60 seconds (on-the-dot). I raised this with masto but I think it is more esphome thing.

Hello, guys, please tell me how to display the ‘%’ character on the screen after displaying the value, maybe someone knows how to do this by some method, such as a screen for a character or creating an additional variable.
It should work, but unfortunately I either have an error, or “%” does not appear at all.
“Humidity: 53.4%”

My codes:

  • platform: homeassistant
    id: humi1
    entity_id: sensor.aq_thp_bedroom_kv_humidity
    on_value:
    then:
    - wait_until:
    switch.is_on: nextion_init
    - lambda: id(disp1).set_component_text_printf(“Home.text2”, “%.1f%”, id(humi1).state);

PS… Initially not finding a solution to my problem, I used the “Text” toolbox from the Nextion Editor.
But later I found a way out, you need to use ‘%%’:
- lambda: id(disp1).set_component_text_printf(“Home.text2”, “%.1f%%”, id(humi1).state);
