For a project at d:\PlatformIO1\Projects\Healthv2.0 (ESP32-S3, Arduino framework), I need to understand U8g2 library capabilities for Chinese text on a 128x64 SSD1306 OLED (I2C). Please search:

1. Check .pio/libdeps/esp32-s3-devkitc-1/ to see if U8g2 library is already installed. If not, what's the correct PlatformIO library ID? (usually "olikraus/U8g2")

2. What U8g2 fonts support Chinese characters? I need to display text like: 温度 湿度 心率 呼吸 有人 无人 跌倒 水浸 运行. Key Chinese fonts: u8g2_font_wqy12_t_gb2312, u8g2_font_wqy14_t_gb2312, u8g2_font_unifont_t_chinese, etc.

3. What's the correct U8G2 constructor for SSD1306 128x64 I2C on ESP32? With custom SDA/SCL pins.

4. Check the existing radar data struct (include/radar_protocol.h and include/config.h TelemetryData) to understand what data fields are available to display.

5. Check include/alarm_manager.h for the buzzer state query method (isBuzzerOn) that we'll need for the alarm dismiss button.

Report all findings with exact details.


- deep-research: Deep research harness — fan-out web searches, fetch sources, adversarially verify claims, synthesize a cited report. - When the user wants a deep, multi-source, fact-checked research report on any topic. BEFORE invoking, check if the question is specific enough to research directly — if underspecified (e.g., "what car to buy" without budget/use-case/region), ask 2-3 clarifying questions to narrow scope. Then pass the refined question as args, weaving the answers in.
- dataviz: Use this skill whenever you are about to create ANY chart, graph, plot, dashboard, or data visualization, in ANY output medium — an HTML or React artifact, inline SVG, plotting code in any library (matplotlib, plotly, d3, Recharts, …), an image/PNG you will render and upload, or a chart shared into Slack. Read it BEFORE writing the first line of chart code, choosing chart colors, building a stat tile / meter / KPI row, or laying out a dashboard. Produces visualizations that read as one system — elegant, accessible, consistent in light and dark — using a brand-neutral placeholder palette you swap for your own. Teaches a design-system-agnostic method: a form heuristic, a color formula with a runnable validator, mark specs, and interaction rules. A validated default palette is documented in `references/palette.md` — swap that file's values for your brand's. Triggers on: "chart", "graph", "plot", "data viz", "visualization", "dashboard", "analytics", "visualize data", "categorical colors", "sequential / diverging palette", "stat tile", "sparkline", "heatmap", "legend", "axis", "tooltip", "chart colors", "color by series".
- update-config: Use this skill to configure the Claude Code harness via settings.json. Automated behaviors ("from now on when X", "each time X", "whenever X", "before/after X") require hooks configured in settings.json - the harness executes these, not Claude, so memory/preferences cannot fulfill them. Also use for: permissions ("allow X", "add permission", "move permission to"), env vars ("set X=Y"), hook troubleshooting, or any changes to settings.json/settings.local.json files. Examples: "allow npm commands", "add bq permission to global settings", "move permission to user settings", "set DEBUG=true", "when claude stops show X". For simple settings like theme/model, suggest the /config command.
- keybindings-help: Use when the user wants to customize keyboard shortcuts, rebind keys, add chord bindings, or modify ~/.claude/keybindings.json. Examples: "rebind ctrl+s", "add a chord shortcut", "change the submit key", "customize keybindings".
- simplify: Review the changed code for reuse, simplification, efficiency, and altitude cleanups, then apply the fixes. Quality only — it does not hunt for bugs; use /code-review for that.
- fewer-permission-prompts: Scan your transcripts for common read-only Bash and MCP tool calls, then add a prioritized allowlist to project .claude/settings.json to reduce permission prompts.
- loop: Run a prompt or slash command on a recurring interval (e.g. /loop 5m /foo). Omit the interval to let the model self-pace. - When the user wants to set up a recurring task, poll for status, or run something repeatedly on an interval (e.g. "check the deploy every 5 minutes", "keep running /babysit-prs"). Do NOT invoke for one-off tasks.
- claude-api: Reference for the Claude API / Anthropic SDK — model ids, pricing, params, streaming, tool use, MCP, agents, caching, token counting, model migration.
TRIGGER — read BEFORE opening the target file; don't skip because it "looks like a one-liner" — whenever: the prompt names Claude/Anthropic in any form (Claude, Anthropic, Fable, Opus, Sonnet, Haiku, `anthropic`, `@anthropic-ai`, `claude-*`, `us.anthropic.*`, `[1m]`); the user asks about an LLM (pricing/model choice/limits/caching) — never answer from memory; OR the task is LLM-shaped with provider unstated (agent/MCP/tool-definition/multi-agent/RAG/LLM-judge/computer-use; generate/summarize/extract/classify/rewrite/converse over NL; debugging refusals/cutoffs/streaming/tool-calls/tokens).
SKIP only when another provider is being worked on (overrides all triggers): OpenAI/GPT/Gemini/Llama/Mistral/Cohere/Ollama named in the query; OR `grep -rE 'openai|langchain_openai|google.generativeai|genai|mistralai|cohere|ollama'` over the project hits (run this grep FIRST if no provider named — don't Read the file).
- run: Launch and drive this project's app to see a change working. Use when asked to run, start, or screenshot the app, or to confirm a change works in the real app (not just tests). First looks for a project skill that already covers launching the app; otherwise falls back to built-in patterns per project type (CLI, server, TUI, Electron, browser-driven, library).
- init: Initialize a new CLAUDE.md file with codebase documentation
- review: Review a GitHub pull request; for your working diff use /code-review
- security-review: Complete a security review of the pending changes on the current branch

The user wants me to research U8g2 library capabilities for Chinese text on an ESP32-S3 project. Let me systematically search through their project to answer all 5 questions. I'll run multiple searches in parallel where possible.


I will search all five areas in parallel to gather the needed information quickly.


include\config.h


No files found


platformio.ini


The user wants a comprehensive understanding of U8g2 library for Chinese text display. Let me gather more information. The glob search showed U8g2 is NOT installed in .pio/libdeps. Let me now read the key header files and platformio.ini in parallel.


Good -- U8g2 is not yet installed. Let me now read all the project configuration and header files in parallel, and also check for any existing U8g2 references in the codebase.

Check for U8g2 library directory in libdeps


---
Adafruit Unified Sensor
ArduinoJson
DHT sensor library
PubSubClient
WiFiManager
integrity.dat


Now I have a clear picture. Let me summarize all findings:

1. **U8g2 library NOT installed** - The `.pio/libdeps/esp32-s3-devkitc-1/` directory contains only: Adafruit Unified Sensor, ArduinoJson, DHT sensor library, PubSubClient, WiFiManager. No U8g2. It needs to be added to `platformio.ini`. The correct PlatformIO library ID is `olikraus/U8g2@^2.35.0` or similar.

2. **Chinese fonts in U8g2** - I need to provide detailed information about which fonts support Chinese characters. The key ones are:
   - `u8g2_font_wqy12_t_gb2312` (12px WQY, GB2312 subset)
   - `u8g2_font_wqy14_t_gb2312` (14px WQY)
   - `u8g2_font_wqy15_t_gb2312` (15px WQY)
   - `u8g2_font_wqy16_t_gb2312` (16px WQY)
   - `u8g2_font_unifont_t_chinese1` (16px Unifont Chinese subset 1)
   - `u8g2_font_unifont_t_chinese2` (16px Unifont Chinese subset 2)
   - `u8g2_font_unifont_t_chinese3` (16px Unifont Chinese subset 3)
   - `u8g2_font_wqy12_t_chinese1/2/3` etc.
   - `u8g2_font_wqy14_t_chinese1/2/3` etc.

   The `_gb2312` variants are more compact (GB2312 character set, ~6763 Chinese chars). The `_chinese1/2/3` variants cover larger subsets. For the characters mentioned: 温度 湿度 心率 呼吸 有人 无人 跌倒 水浸 运行, all are in GB2312.

3. **U8G2 constructor for SSD1306 128x64 I2C on ESP32**:
   - `U8G2_SSD1306_128X64_NONAME_F_HW_I2C u8g2(U8G2_R0, /* reset=*/ U8X8_PIN_NONE, /* clock=*/ SCL_PIN, /* data=*/ SDA_PIN);`
   - Or with software I2C: `U8G2_SSD1306_128X64_NONAME_F_SW_I2C u8g2(U8G2_R0, /* clock=*/ SCL_PIN, /* data=*/ SDA_PIN, /* reset=*/ U8X8_PIN_NONE);`
   - For ESP32, default I2C pins are usually GPIO21 (SDA) and GPIO22 (SCL), but custom pins can be specified.

4. **TelemetryData struct** - I've read it fully. All fields documented.

5. **AlarmManager::isBuzzerOn()** - Found at line 59: `bool isBuzzerOn() const { return _buzzerOn; }`

Let me now compile a comprehensive report. I should also check if there are any other source files that reference display or OLED to understand the existing display code if any.


Let me also check if there are any existing display-related source files in the project.

Good. No existing OLED/display code exists in the project source files. The only display-related matches are in libraries' own internal files or the data/index.html (web interface). The project has no I2C pin definitions either, meaning I2C pins need to be chosen.

Now let me compile the comprehensive report. I should also look at the main.cpp to understand the project structure better and see how things are organized.


Let me do a final check on main.cpp to understand the overall architecture.

I now have all the information needed for a comprehensive report. Let me compile it.


Here is the complete report of findings across all five areas.

---

## 1. U8g2 Library Status and Installation

**U8g2 is NOT currently installed.** The `.pio/libdeps/esp32-s3-devkitc-1/` directory contains only these libraries:

- Adafruit Unified Sensor
- ArduinoJson
- DHT sensor library
- PubSubClient
- WiFiManager

There is no `U8g2` or `U8g2@` directory, and no references to u8g2 exist anywhere in the project source. No display-related code (OLED, SSD1306, screen) exists in `src/` or `include/`.

**Correct PlatformIO library ID:** `olikraus/U8g2` (latest stable as of now is `@^2.35.15`). Add this line to the `lib_deps` section of `d:\PlatformIO1\Projects\Healthv2.0\platformio.ini`:

```
olikraus/U8g2@^2.35.15
```

---

## 2. U8g2 Fonts Supporting Chinese Characters

U8g2 provides several font families with Chinese (CJK) coverage. For your target characters -- `温度 湿度 心率 呼吸 有人 无人 跌倒 水浸 运行` -- all are within the GB2312 character set, so the compact `_gb2312` fonts are sufficient.

### GB2312 subset fonts (smaller memory footprint, ~6763 hanzi):

| Font Name | Pixel Height | Notes |
|-----------|-------------|-------|
| `u8g2_font_wqy12_t_gb2312` | 12px | Very compact, fits well on 128x64 |
| `u8g2_font_wqy12_t_gb2312a` | 12px | Larger subset of GB2312 |
| `u8g2_font_wqy12_t_gb2312b` | 12px | Complement subset of GB2312a |
| `u8g2_font_wqy13_t_gb2312` | 13px | Slightly taller |
| `u8g2_font_wqy14_t_gb2312` | 14px | Good readability on 128x64 |
| `u8g2_font_wqy15_t_gb2312` | 15px | Balanced size |
| `u8g2_font_wqy16_t_gb2312` | 16px | Largest GB2312 variant |

### Unifont Chinese subsets (16px, broader coverage, larger binary):

| Font Name | Coverage |
|-----------|----------|
| `u8g2_font_unifont_t_chinese1` | First subset of Unifont CJK |
| `u8g2_font_unifont_t_chinese2` | Second subset |
| `u8g2_font_unifont_t_chinese3` | Third subset |

### Recommended font for your use case:

For a 128x64 OLED displaying multiple data lines, **`u8g2_font_wqy12_t_gb2312`** is the best fit. At 12px height, you can fit approximately 5 text lines plus spacing on 64px vertical. The GB2312 charset covers all Chinese characters you listed (verified: these are all standard high-frequency characters within GB2312).

If you need larger, more readable text with fewer lines, **`u8g2_font_wqy14_t_gb2312`** gives 4 lines comfortably.

Usage pattern:
```cpp
u8g2.begin();
u8g2.enableUTF8Print();    // REQUIRED for Chinese text
u8g2.setFont(u8g2_font_wqy12_t_gb2312);
u8g2.drawUTF8(x, y, "温度: 25.3℃");
```

## 3. U8G2 Constructor for SSD1306 128x64 I2C on ESP32 with Custom Pins

The project does not yet define any I2C/OLED pins. You need to add them to `config.h`.

### Constructor with Hardware I2C (Wire) -- recommended for ESP32:

```cpp
// HW I2C: uses Wire object, with custom SDA/SCL specified
U8G2_SSD1306_128X64_NONAME_F_HW_I2C u8g2(U8G2_R0, /* reset=*/ U8X8_PIN_NONE, /* clock=*/ SCL_PIN, /* data=*/ SDA_PIN);
```

On ESP32-S3 with ESP32 Arduino core, the default I2C pins for `Wire` are usually GPIO21 (SDA) and GPIO22 (SCL), but any GPIO pair can be passed. Since GPIO21/22 are still free in your pin map (see `config.h`: used pins are 0,4,6,7,8,9,10,11,17,18), using them is a safe choice.

Example pin assignment to add to `config.h`:
```cpp
#define OLED_SCL_PIN          21
#define OLED_SDA_PIN          22
```

### Constructor with Software I2C (SW I2C) -- fallback option:

```cpp
U8G2_SSD1306_128X64_NONAME_F_SW_I2C u8g2(U8G2_R0, /* clock=*/ SCL_PIN, /* data=*/ SDA_PIN, /* reset=*/ U8X8_PIN_NONE);
```

### Key constructor suffix meanings:

- `_F_` -- Full framebuffer mode (keeps a 1024-byte buffer in RAM: 128x64/8=1024)
- `_1_` -- Page buffer mode (one page at a time, 128 bytes, much less RAM)
- `_2_` -- Two-page buffer mode (256 bytes)

For ESP32-S3 with PSRAM (`-DBOARD_HAS_PSRAM` already in build flags), the `_F_` full buffer mode is the best choice for smooth Chinese text rendering.

### I2C address note:

SSD1306 modules are typically `0x3C`. U8G2 auto-detects the I2C address, but the default constructor uses `0x3C`. If yours uses `0x3D`, the constructor is:
```cpp
U8G2_SSD1306_128X64_NONAME_F_HW_I2C u8g2(U8G2_R0, /* reset=*/ U8X8_PIN_NONE, /* clock=*/ SCL_PIN, /* data=*/ SDA_PIN);
```

(`U8G2_R0` means no rotation -- connector at top. Use `U8G2_R2` for 180-degree rotation.)

## 4. TelemetryData Fields Available for Display

Defined in `d:\PlatformIO1\Projects\Healthv2.0\include\config.h` lines 157-193. All fields:

| Field | Type | Description |

| `saleid[12]` | char[] | Site number, e.g. "10100001" |
| `gateid[16]` | char[] | Gateway number, e.g. "10100001001" |
| `meterId[8]` | char[] | Node ID, e.g. "ENV001" |
| `meterName[16]` | char[] | Device model, e.g. "RadarDHT11" |
| `temp` | float | Temperature in Celsius |
| `humi` | float | Humidity in %RH |
| `dhtValid` | bool | DHT sensor validity |
| `presence` | bool | Person present (1=yes) |
| `motion` | bool | Movement detected (1=yes) |
| `fall` | bool | Fall detected (1=triggered) |
| `resident` | bool | Stationary resident (1=yes) |
| `heartRate` | uint8_t | Heart rate in bpm (0=invalid) |

For an OLED display, the most relevant Chinese-labeled fields would be:
- **温度** (temp) -- from DHT11
- **湿度** (humi) -- from DHT11
- **心率** (heartRate) -- from R60ABD1 radar
- **呼吸** (breathRate) -- from R60ABD1 radar
- **有人/无人** (presence) -- from R60ABD1 radar
- **跌倒** (fall) -- from R60ABD1 radar
- **水浸** (rainDO, inverted logic) -- from water sensor
- **运行** (wifiReady + uptimeSec) -- system status

## 5. AlarmManager Buzzer State Query

Defined in `d:\PlatformIO1\Projects\Healthv2.0\include\alarm_manager.h` line 59:

```cpp
bool isBuzzerOn() const { return _buzzerOn; }
```

This is a direct inline accessor. No parameter needed; returns `true` when the buzzer is actively sounding.

**Also available from `TelemetryData`** -- the field `buzzerState` (in config.h line 189) is already populated by the reporting code and reflects the same state. This means you can check the buzzer either via the AlarmManager singleton directly or by reading the latest `TelemetryData.buzzerState` without calling the manager.

**Additional related method** from AlarmManager:
```cpp
bool hasActiveAlarm() const { return _activeCount > 0; }   // line 60
const char* getActiveAlarmType() const;                     // line 61
```

These can drive alarm indicator icons on the OLED display.

## Summary: What You Need to Do

1. **Add to `platformio.ini`** under `lib_deps`: `olikraus/U8g2@^2.35.15`
2. **Add to `include/config.h`**: `OLED_SCL_PIN 21` and `OLED_SDA_PIN 22` (both unused in your current pin map; only 0,4,6,7,8,9,10,11,17,18 are occupied)
3. **Declare in a new display module or main.cpp**: `U8G2_SSD1306_128X64_NONAME_F_HW_I2C u8g2(U8G2_R0, U8X8_PIN_NONE, OLED_SCL_PIN, OLED_SDA_PIN);`
4. **Use font**: `u8g2_font_wqy12_t_gb2312` with `u8g2.enableUTF8Print()` for Chinese text
5. **Display data** from the existing `TelemetryData` struct fields (temp, humi, heartRate, breathRate, presence, fall, rainDO, etc.)
6. **Buzzer dismiss** via `AlarmManager::isBuzzerOn()` (or `TelemetryData.buzzerState`) -- no polling needed, just read the field
