A24 configure yaml for ESPhome

[kiloptero]

hi! there is any reason to use inverted= true in the config? this is to use with NC contactor?
im asking because in the power distribution box diagram you use a NO contactor and i already ourchase like 32 units... thanks a lot!

Reverse the logic of all outputs

thanks.. the yaml send this error when I try to install the yaml file

INFO ESPHome 2026.3.3
INFO Reading configuration /config/esphome/a24-1.yaml...
Failed config

esphome: [source /config/esphome/a24-1.yaml:2]
name: a24

Please remove the `platform` key from the [esphome] block and use the correct platform component. This style of configuration has now been removed.
platform: ESP32
board: esp32dev

[admin]

because now esphome yaml syntax is updated. just do as esphome tip.

[kiloptero]

any oficial new yaml? pi

[admin]

this is updated, it can directly to use.

thanks!!! amazing support like always!

[admin]

you are welcome.

[kiloptero]

hi any idea why the thermocouple show a really low level of temperature?
any way to calibrate?

[admin]

do you use by ESPHome?
can you take a photo , how you wire your sensor.
