Hello,
Syntax question regarding displaying temp. reading from bme280 sensor.

Om a esp8266 board the sensor is measuring temp, humidity and pressure.
On e seperate esp32 I would like to display this bme280 temperature.
I succeed to display my name ( huray) the time but no succes th display the temp.

snippet from my script
sensor:

  • platform: homeassistant
    id: bme280_temperature
    entity_id: bme280.temperature
    unit_of_measurement: “°C”

time:

  • platform: homeassistant
    id: homeassistanttime

Example configuration entry

spi:
clk_pin: GPIO18
mosi_pin: GPIO23
miso_pin: GPIO12

color:

  • id: my_red
    red: 5%
    green: 50%
    blue: 50%

font:

  • file: ‘/config/esphome/.esphome/custom_components/arial.ttf’
    id: font1
    size: 30

Example configuration entry

display:

  • platform: st7735
    model: “INITR_BLACKTAB”
    reset_pin: 19
    cs_pin: 22
    dc_pin: 21
    rotation: 0
    device_width: 128
    device_height: 160
    col_start: 0
    row_start: 0
    eight_bit_color: true
    update_interval: 5s

    lambda: |-
    it.fill(Color::BLACK);
    it.strftime(0, 60, id(font1), TextAlign::BASELINE_LEFT, “%H:%M:%S”, id(homeassistanttime).now());
    if (id(bme280_temperature).has_state()) {
    it.printf(0, 0, id(font1), TextAlign::TOP_LEFT ,“°C”, id(bme280_temperature).state);
    }
    somewhere some howe I go wrong. But where? Many attempt I had made no succes so far.
    It drives me mad?
    Any push in the correcr direction is very much apreciated.

Try code tags to
make

your
`yaml`

readable :tada:

Hi,

Thanks for tour tip.
Just another question mark? code tags?
But any way I figgered out to have my bmp data on the display.
I changed to the same board. Now I will split it up again on two boards.

here my snippet. sorry no code tags if I find them I will use them.

Example configuration entry

display:

  • platform: st7735
    model: INITR_BLACKTAB
    reset_pin: 13
    cs_pin: 14
    dc_pin: 12
    rotation: 0
    device_width: 128
    device_height: 160
    col_start: 0
    row_start: 0
    eight_bit_color: true
    update_interval: 5s

    lambda: |-
    it.fill(Color::BLACK);
    it.strftime(0, 26, id(font1), TextAlign::BASELINE_LEFT, “%H:%M:%S”, id(homeassistant_time).now());
    it.printf(100, 126, id(font1), TextAlign::BASELINE_LEFT, “°C”);
    it.printf(30, 86, id(font1), TextAlign::BASELINE_LEFT,“Theo”);
    it.printf(10, 126,id(font1), TextAlign::BASELINE_LEFT,"%.1f", id(bmptemp).state );
    it.printf(10, 146,id(font1), TextAlign::BASELINE_LEFT,"%.1f", id(bmppres).state );
    regards, ilioss
