platformio_override.sample.ini -D USERMOD_DALLASTEMPERATURE incorrect.

[mike-s123]

What happened?

platformio_override.sample.ini contains multiple examples including "-D USERMOD_DALLASTEMPERATURE". This does not work.

To Reproduce Bug

Compiling with -D USERMOD_DALLASTEMPERATURE does not result in Dallas DS18B20 temperature support being included.

Expected Behavior

Temperature support should be included in the compiled binary.

Install Method

Self-Compiled

What version of WLED?

WLED 16.0.0 release

Which microcontroller/board are you seeing the problem on?

ESP32

Relevant log/trace output

Anything else?

To include DS18B20 support, the correct configuration in platformio_override.sample.ini should be similar to:

custom_usermods = ${env:esp32dev.custom_usermods}
Temperature

This is documented in https://github.com/wled/WLED/blob/main/usermods/Temperature/readme.md

@DedeHai, based on my search, there is no open PR that specifically fixes the -D USERMOD_DALLASTEMPERATURE issue described in this ticket.

The closest open PR is #5190 "platformio sample cleanup" by @netmindz, which does modify platformio_override.sample.ini, but its scope is limited to removing legacy/bespoke board configurations — it does not address the incorrect USERMOD_DALLASTEMPERATURE build flag. You've already approved that PR, but the Dallas Temperature fix still needs to be applied separately.

The fix would involve replacing occurrences of -D USERMOD_DALLASTEMPERATURE in platformio_override.sample.ini with the correct custom_usermods approach:

custom_usermods = ${env:esp32dev.custom_usermods}
    Temperature

Would you like me to open a new issue to track this fix, or would you prefer to handle it directly?
