Walkthrough

The PR updates ESP32 IDF V5 platform versions and settings, raises the PlatformIO requirement, removes ESP32-C5 NTP overrides, and adjusts SHA1, time_t, and chip-revision compatibility logic.

Changes

ESP32 IDF V5 compatibility

Layer / File(s)	Summary
ESP32 IDF V5 platform update platformio.ini, requirements.in, requirements.txt, wled00/cfg.cpp, wled00/set.cpp	The platform uses Tasmota 2026.05.50, shared pioarduino settings, and the __unreachable compatibility definition. ESP32-C5 uses the shared platform settings. ESP32-C5-specific NTP overrides were removed. PlatformIO now requires version 6.1.19.
Library compatibility guards wled00/mbedtls_sha1_shim.cpp, wled00/src/dependencies/time/TimeLib.h	The SHA1 shim checks MBEDTLS_SHA1_C. The fallback time_t definition also checks _TIME_T_DECLARED.
ESP32 revision diagnostics wled00/wled.cpp	ESP32 setup logging uses the IDF 5+ major.minor chip-revision format and retains the legacy format for older IDF versions.

Estimated code review effort: 2 (Simple) | ~10 minutes

tested on ESP32 classic, works.

@softhack007 I got my C5. It works with latest tasmota and also enabling NTP gives me no crashes.

Merge once you are happy please @softhack007

@netmindz I'll take a look on Sunday 👍

Edit: on Monday

E (852) MSPI Timing: Failed to allocate dummy cacheline for PSRAM memory barrier!

This seems to be a known "hickup" on -C5 with PSRAM espressif/arduino-esp32#12587

[softhack007]

It works with latest tasmota and also enabling NTP gives me no crashes.

I can also cross-check this on my board. The -C5 crash was always kind of mysterious - maybe it was a consequence of another bug we already fixed in main 🤔

@DedeHai both observations confirmed on my board (C5 devkit N8R4, chip revision v1.0, with PSRAM)

• no more crashes on NTP receive
• works with tasmota

✅ Action performed

Full review finished.

[softhack007]

Looks good for me now.
@DedeHai can you give it a quick spin on your boards? If nothing unexpected comes up, we should be good to merge.

I am afk until next monday
