The 96-slot message ring can overflow when there is sustained traffic across many threads. When ring wraparound silently overwrites a channel's messages, thread.unread stays non-zero but getThreadMessageIndexes returns 0 — producing a badge with a count but an empty chat on open. The same phantom persists across reboots because unread is saved to disk independently of the ring contents. Fix has three parts: 1. counted_as_unread per UIMessage (RAM-only): set true when a message is the reason a thread's unread counter was incremented. Cleared when the thread is marked read, so future evictions of those slots don't double-decrement. 2. Eviction hook in appendMessage: before overwriting a ring slot, decrement its thread's unread if the slot was counted_as_unread. Keeps the counter in sync as the ring wraps. 3. Post-load reconciliation in loadHistoryFromStorage: after restoring thread+message state from disk, any thread whose persisted unread count exceeds its actual incoming messages in the ring gets clamped (or reset to 0 if the ring has nothing for it). Also reconstructs the counted_as_unread flags so evictions after boot are tracked. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
A real touchscreen UI for your mesh radio. · open source · GPL-3.0
Touch-UI MeshCore companion-radio firmware for the LilyGo T-Deck / T-Deck Plus and Heltec V4 + TFT (ESP32-S3).
An LVGL touch UI — map, chat, contacts, channels, settings — split out of
meshcomod. The app depends on a
MeshCore fork via PlatformIO lib_deps.

heltec_v4_tft_companion_radio_usb_tcp_touch
Architecture
This repo holds only the app: the companion_radio glue, the ui-touch
LVGL UI, the two boards' glue/variants, and platformio.ini. The MeshCore
core is not vendored here — it's pulled as a library via lib_deps from the
ALLFATHER-BV/meshcomod monorepo
(the same repo as the non-touch firmware), pinned by a lean source-only core-*
git tag. The touch-app files this repo owns (TouchPrefsStore, WifiRuntimeStore,
the transports, …) are dropped from the lib via -DMC_VENDORED_TOUCH_APP so they
aren't compiled twice. The build is byte-identical to the original in-tree
meshcomod firmware.
Build
PlatformIO pulls the core fork and all libraries automatically:
pio run -e heltec_v4_tft_companion_radio_usb_tcp_touch # Heltec V4 TFT
pio run -e LilyGo_TDeck_companion_radio_touch # LilyGo T-Deck
# or just `pio run` to build both
Flash with the NVS-preserving 4-component chain (bootloader / partitions /
boot_app0 / firmware at 0x0 / 0x8000 / 0xe000 / 0x10000) so saved Wi-Fi
credentials survive — not a merged image, which 0xFF-pads and wipes NVS.

License
GPL-3.0-or-later — see LICENSE. wadamesh is copyleft: anyone who distributes a build or a fork must also make their source available under the GPL. This keeps the UI open and concentrates community effort instead of fragmenting it into closed forks.
wadamesh incorporates and depends on MeshCore (MIT, © Scott Powell / rippleradios.com) and other third-party components — see NOTICE for the full list and their licenses. MeshCore-derived files keep their MIT notices; the combined work is distributed under the GPL (MIT is GPL-compatible). The MeshCore fork that wadamesh builds against stays MIT on purpose, so its Wi-Fi/BLE hooks remain upstreamable to MeshCore.
