Quote/0

A Quote/0 Client + Streamlit App and Notes about SSPAI's Quote/0

Firmware 1.6.x · client v0.2.0 targets the current authV2 open API

The device had a major firmware update. The open API moved to https://dot.mindreset.tech/api/authV2/open/device/{deviceId}/{image|text} (device id now in the URL path). The legacy /api/open/{image|text} endpoints are deprecated but still forward to the new API (no removal date announced). Quote0(...) defaults to authV2; pass legacy=True to use the old endpoints. Official docs source: https://github.com/MindReset/dot_web_docs (en-US/service/open/image_api.mdx, text_api.mdx).

Getting Started

1. Connect Type-C
2. Bind device in Mobile App
3. Select content to show
4. (optional) Request API key in App (and get Device ID) -> use API
5. (optional) Setup .env (follow .env.example)

• Update Software
  • update firmware
  • reset network
  • reset device

NOTE: to test if the display is normal you can use the script checkerboard_gray.sh

CLI

• quote0 · PyPI

# Install this package (core client is lightweight: requests + pydantic + pillow + tyro)
$ uv tool install quote0
# Optional extras:
#   quote0[ui]        Streamlit web app (streamlit, watchdog)
#   quote0[examples]  chart-rendering example scripts (matplotlib, numpy)

# Image API
# NOTE: the CHECKERBOARD_GRAY pattern is good to test if your monitor is defect
$ quote0 image --preset CHECKERBOARD_GRAY --api-key dot_app_.... --device-id ABCD1234ABCD
🖼️  Using preset image: checkerboard_gray
📤 Sending image to Quote/0 device... (border: WHITE)
✅ Image sent successfully!

# Text API with Environment Variable
export DOT_API_KEY=dot_app_....
export DOT_DEVICE_ID=ABCD1234ABCD

$ quote0 text --title Hello --message World
📤 Sending text to Quote/0 device...
✅ Text sent successfully!

Python

from quote0 import Quote0

client = Quote0(api_key="dot_app_...", device_id="ABCD1234ABCD")  # authV2 by default
client.send_text(title="总市值 12.34M", message="持仓盈亏 +98,765", signature="14:31")
client.send_image(image_base64=b64, dither_type="DIFFUSION")

# new authV2 fields:
#   send_text(..., styles={"fontSize": 18}, task_key=..., task_alias=...)
#   send_image(..., task_key=..., task_alias=...)
# legacy endpoints (device id in body):
#   Quote0(api_key, device_id, legacy=True)

Streamlit UI

• Quote/0 API Playground · Streamlit

uv sync --extra ui   # or: pip install "quote0[ui]"
uv run streamlit run Streamlit_Playground.py

Todo

• Determine whether same API Key can control multiple Device ID

Notes / gotchas:

• authV2 404 on push / screen doesn't change: the device needs an Open API content slot in its loop task, otherwise pushed content has nowhere to show. Add an Open API card to the device in the Dot App.
• Rate limit is 10 requests/second; image payload max 3MB (base64) and image/ icon may also be a public http(s) URL.
• Somehow Image API's "link" didn't work => NFC is not working
