Thermostat cooking at high temperature

1

Hi there, I flashed an ESP12 with built in realy, wired a MAX6675 with a K-thermocouple.
I would like to make a thermostat for cooking stuff at high temperature: 160-300°C.
I made a slow PWM in Arduino (with a SSR) for a similar project, but I would like to start easy.

I managed to make a simple thermostat, but I can’t manage to build a control that goes over 30°C.
I tried this way: Thermostat Card min and max temp display - #4 by AhmadK
but without a success.

Any suggestion?

thanks

Update: managed to change the gauge temperature using the correct ID of the thermostat in the customize.yaml file.

climate.thermostat_climate_controller:
    max_temp: 350
    min_temp: 8

I then added the visual option in the firmware:

visual:
      min_temperature: 5 °C
      max_temperature: 400 °C
      temperature_step: 1 °C
