Compile time errors

ESPHome

Hi guys,
Could someone more knowledgeable than me with ESPhome please see where I’m going wrong here.

The errors on compile in Python are:

src\main.cpp:242:7: error: stray '\302' in program
       if (temperature->has_state()) { it.printf(10, 0, my_font, TextAlignTOP_LEFT , %.1f°, temperature->state); }
       ^
src\main.cpp:242:7: error: stray '\260' in program

       if (temperature->has_state()) { it.printf(10, 0, my_font, TextAlignTOP_LEFT , %.1f°, temperature->state); }
                        ^

                                                                 ^

       if (temperature->has_state()) { it.printf(10, 0, my_font, TextAlignTOP_LEFT , %.1f°, temperature->state); }

And my mashup of code:

    lambda:
      if (id(temperature).has_state()) {
        it.printf(10, 0, id(my_font), TextAlignTOP_LEFT, %.1f°, id(temperature).state);
      }

    id: temperature
    temperature:

    update_interval: 60s

Thanks in advance for any tips!

Try adding this after the lambda

    lambda: |-

I’ve marked this solved by micque (thanks micque!) but it turned out that wasn’t the only bad syntax :slight_smile:
Jesserockz on Discord was super helpful with straightening it out. Thanks Jesse!
I was also battling bad sensors that I must’ve damaged earlier on, just to double up on the experience :wink:

Here’s the working code for anyone else’s reference:
