* ESP8266: fix ESP_getMaxAllocHeap() and ESP_getHeapFragmentation()
Both functions returned wrong values: ESP_getMaxAllocHeap() returned
ESP.getFreeHeap() (total free, not largest contiguous block);
ESP_getHeapFragmentation() read ummHeapInfo.maxFreeContiguousBlocks,
which is only valid immediately after a umm_info() heap walk.
Fix: cache the result of umm_max_block_size() in ESP_UpdateHeapMetrics().
The cache is refreshed once per second when SetOption130 is active, and
on demand in CmndStatus() before Status 4 is output. Both getter functions
read the cached value; the call site overhead is a single integer read.
umm_max_block_size() is unconditionally available (UMM_INFO is hardcoded
in the Arduino ESP8266 umm_malloc_cfg.h), so no build flags are required.
Status 4 (StatusMEM) gains two ESP8266-specific fields: MaxFreeBlock (KB)
and Frag (%).
* ESP8266: add heap OOM diagnostics, Status 4 fields, Status 44 dump
OOM event monitoring (requires UMM_INLINE_METRICS or UMM_STATS_FULL):
- ESP_HeapOomCheck(): called once per second; logs the OOM counter delta
when the counter changes ("OOM: count N (+M)")
- ESP_HeapOomTest(): logs current OOM count on demand
Status 4 (StatusMEM) gains additional ESP8266-specific fields when the
corresponding build flags are active:
- OomCount: cumulative out-of-memory events (UMM_INLINE_METRICS or
UMM_STATS_FULL)
- HeapLwm (KB): heap low-watermark since boot (UMM_STATS_FULL)
- MaxAllocSz (bytes): peak single allocation size (UMM_STATS_FULL)
Status 44 (ESP8266-only diagnostic command):
- Triggers umm_info(nullptr, true) to print a full heap block map to
the serial console
- Calls ESP_HeapOomTest() to log the current OOM count
- Returns {"Status44":{"HeapDump":"serial"}}
- Status 44 is accepted regardless of MAX_STATUS
Build flags UMM_STATS_FULL and UMM_INLINE_METRICS can be enabled via
platformio_override.ini build_flags; documented in
platformio_override_sample.ini.
* Replace old software-defined library arduino-vid6608 with hw-defined esp-32-vid6608
* VID6608: Rework integration to allow select RMT/SW method by using the `VID6608_RMT` option
* VID6608: Tune library inclusion for RMT version
* The RMT version is not supported on ESP32-C2, library excluded
* Add more clear error message, if RMT is requested, but not supported
* Add support for multi-byte characters like emojis (💡) in WebButton labels for light device toggle buttons
- Remove the 3-character buffer truncation of light device toggle button labels allowing multi-byte characters like emojis
- Rely on CSS to handle truncation and add `max-width:0` to the td so it respects the provided percentage width instead of expanding to fit content
- Wrap button content in a span with overflow handling to prevent layout breakage
* Use localized `D_BUTTON_TOGGLE` for light device button default text
* Improve UTF-8 support in light device WebButton text
- Add `Utf8Truncate` function in `support.ino` to truncate UTF-8 strings to a max chars limit or max visual width limit
- Truncate light device button text to max 4 chars or max width of 4 before passing to button HTML template
- cache calls to GetWebButton so only called once and update bool var from `set_button` to `has_web_button`.
* Small tweaks to improve clarity in Utf8Truncate on codepoint limits and visual width handling
* Correctness fixes

- Replace broken "http" and "://" in file condition with file.startswith(("http://", "https://")) — the original always evaluated "http" as truthy and only tested for "://".
- Strip whitespace and skip blank lines from custom_files_upload entries, matching the pattern in solidify-from-url.py.
- Resolve relative local paths against $PROJECT_DIR rather than the build-time CWD.
- Replace 8-bit per-channel math with 10-bit intermediates to preserve color ratios at low brightness.
- When SetOption105 (white blend mode) is enabled on a 4-byte RGBW strip, extract the minimum RGB component as a white channel (scaled by rgbwwTable[3]) rather than zeroing it, mirroring the logic in xdrv_04_light.ino.
- Gamma correction is applied via ledGamma10_10 throughout, including the extracted white channel.
- solidify_all_python.be imports tasmota_defines during solidification, but the actual file is generated post-compilation by gen-berry-defines.py. If it doesn't exist yet, solidification fails. Create an empty stub before calling prepareBerryFiles so the import succeeds regardless of build order.
* Add local file support to solidify-from-url.py and fix URL rename alias bug
- Add support for local .be file paths (absolute or PROJECT_DIR-relative) in prepareBerryFiles used by custom_berry_solidify project option in solidify-from-url.py
- Fix URL path to use "/" as separator instead of os.path.sep, and pass the rename alias to addHeaderFile so the solidified header name matches the actual target filename
* solidify-from-url: replace compiled berry binary with berry_port Python interpreter
- Remove ensureBerry() and the shell invocation of the compiled `berry` binary.
- Instead run solidify_all_python.be via `python3 -m berry_port`, matching how gen-berry-structures.py drives solidification for all other berry modules.
- Use Popen to filter routine per-file output and call env.Exit on failure.
* wrap printf with stubs
* Remove flash savings message from wrap_printf
Removed print statement indicating flash savings for ESP8266.
* safe more by using rom function
- Route single-specifier hostnames through Format() so patterns like %NX (last N MAC hex chars) work correctly, while preserving the existing two-specifier %s-%04d behavior via snprintf
- Update comment in my_user_config.h to accurately describe chip ID rather than MAC
- Position tracking (abs_position, rel_position) was previously skipped when SEESAW_ENCODER_LIKE_ROTARY light control mode was active due to an early return. Moved position updates before the light control block so Show() and Telemetry always reflect current position.
- Also adds Pos (global relative position) alongside Pos1/Pos2 in JSON telemetry responses, rule triggers, and the web UI display.
