Deploy MimiClaw

End-to-end guide for deploying MimiClaw to an ESP32-S3 dev board.

Prerequisites

Hardware

• ESP32-S3 dev board with 16 MB flash + 8 MB PSRAM (e.g. Xiaozhi AI board, ~$5-10)
• USB Type-C data cable (not charge-only)

Software

• ESP-IDF v5.5+ installed and working

  # Install: https://docs.espressif.com/projects/esp-idf/en/v5.5.2/esp32s3/get-started/
  # Verify:
  idf.py --version   # should show >= 5.5
  

Credentials (get these first)

• WiFi SSID + password — the network the ESP32 will connect to
• Telegram Bot Token — create via @BotFather on Telegram
• Anthropic API Key — from console.anthropic.com
• (Optional) Brave Search API key — from brave.com/search/api
• (Optional) HTTP proxy host:port — if in China or restricted network

Step 1: Clone and Set Target

git clone https://github.com/memovai/mimiclaw.git
cd mimiclaw
idf.py set-target esp32s3

Step 2: Configure Secrets

cp main/mimi_secrets.h.example main/mimi_secrets.h

Edit main/mimi_secrets.h — fill in ALL required fields:

#define MIMI_SECRET_WIFI_SSID       "YourWiFiName"        // REQUIRED
#define MIMI_SECRET_WIFI_PASS       "YourWiFiPassword"     // REQUIRED
#define MIMI_SECRET_TG_TOKEN        "123456:ABC-DEF..."    // REQUIRED
#define MIMI_SECRET_API_KEY         "sk-ant-api03-..."     // REQUIRED
#define MIMI_SECRET_MODEL           ""                     // optional, defaults to claude-opus-4-5
#define MIMI_SECRET_SEARCH_KEY      ""                     // optional: Brave Search API key
#define MIMI_SECRET_PROXY_HOST      ""                     // optional: e.g. "192.168.1.83"
#define MIMI_SECRET_PROXY_PORT      ""                     // optional: e.g. "7897"

Proxy setup (China users): If you need a proxy to reach Telegram/Anthropic APIs, set both PROXY_HOST and PROXY_PORT. The proxy machine must:

• Be on the same LAN as the ESP32
• Support HTTP CONNECT method (Clash, V2Ray, etc.)
• Have "Allow LAN connections" enabled

Step 3: Build

idf.py fullclean && idf.py build

IMPORTANT: Always fullclean after changing mimi_secrets.h — the secrets are compiled into the binary.

Expected output: Project build complete. To flash, run: idf.py flash

Build Troubleshooting

Step 4: Find Serial Port

# macOS
ls /dev/cu.usb*

# Linux
ls /dev/ttyACM* /dev/ttyUSB*

Common ports:

• macOS USB-OTG: /dev/cu.usbmodem1101 or /dev/cu.usbmodem11401
• Linux: /dev/ttyACM0

If no port shows up:

• Try a different USB cable (must be data cable, not charge-only)
• Try a different USB port
• Check if board has a power LED lit

Step 5: Flash

idf.py -p PORT flash monitor

Replace PORT with your actual port. Example:

idf.py -p /dev/cu.usbmodem1101 flash monitor

The monitor shows boot logs. Look for:

I (xxx) mimi: MimiClaw - ESP32-S3 AI Agent
I (xxx) mimi: PSRAM free: ~8000000 bytes
I (xxx) wifi: WiFi connected: 192.168.x.x
I (xxx) telegram: Telegram bot token loaded
I (xxx) mimi: All services started!

Exit monitor: Ctrl+]

Step 6: Verify

1. Open Telegram, find your bot (the one you created with BotFather)
2. Send: Hello
3. You should see "mimi is working..." followed by a response
4. Send: What time is it? — tests the get_current_time tool
5. Send: Search for latest news about ESP32 — tests web_search (if Brave key set)

Post-Deploy: Runtime Configuration

Connect via serial (idf.py -p PORT monitor) and use CLI commands:

mimi> config_show                  # see current config
mimi> wifi_set NewSSID NewPass     # change WiFi
mimi> set_tg_token 123456:ABC...   # change Telegram token
mimi> set_api_key sk-ant-...       # change API key
mimi> set_model claude-sonnet-4-5  # change model
mimi> set_proxy 192.168.1.83 7897  # set proxy
mimi> clear_proxy                  # remove proxy
mimi> heap_info                    # check memory
mimi> restart                      # reboot

CLI settings are stored in NVS flash and take priority over build-time values.

OTA Update (over WiFi)

After initial USB flash, future updates can be done over WiFi:

1. Build new firmware: idf.py build
2. Host the .bin file on a local HTTP server:

   cd build && python3 -m http.server 8080
   

3. Send to your bot on Telegram or use the OTA CLI command with the URL:

   http://YOUR_PC_IP:8080/mimiclaw.bin
