SlimFit · Weight-management Check-ins

Push daily plans to NOTE4 across five time slots and check in with the middle button. A companion WeChat Mini Program provides weekly reports and device management; the backend can generate and adjust plans based on recent completion. Requires a self-hosted backend and LAN agent.

What it can do

Daily plans and tasks across five time slots on a 400×300 grayscale screen
Short-press the middle button to complete a task; view check-ins and weekly reports on your phone
Backend plan generation and adjustments based on recent completion, with a default mock mode
Agent polls the backend, pushes images over the LAN and reports device button events

Install & use

Install the local application

Check the backend and images in mock mode first, then connect your NOTE4 and WeChat Mini Program.

Public source

Monochrome NOTE4 · Firmware 3.7.5 / SDK 0.2.0 · Always-on computer or NAS · Node.js 20+, Rust, CMake · WeChat DevTools

The agent must share the NOTE4 LAN. Enable the device’s keep-connected setting and avoid simultaneous management clients. Follow the author’s host-network setup for containers. Device images use local push, not Zectrix Cloud Open API; NOTE4C support is not declared.

  1. Prepare dependencies and SDK

    Follow DEPLOY.md to install Node.js 20+, Rust stable, CMake, a C/C++ toolchain and Chinese fonts. Fetch the separately maintained official SDK with scripts/fetch-sdk.sh, then configure your network addresses using LAN_DEPLOY.md.

  2. Start the backend and Mini Program

    Initialize the database and start the backend as documented, retaining AI_PROVIDER=mock and WECHAT_MOCK=1 for a demo. Import miniprogram into WeChat DevTools and set your API address. Real use requires your own accounts, service credentials and HTTPS domain.

  3. Pair and verify NOTE4

    Build the agent and pair it using a code from the Mini Program. Check rendered images with --dry-run before starting with your backend address and NOTE4 IP. Verify image delivery, button check-ins and reporting; configure and test real AI and WeChat subscriptions separately.

Frequently asked questions

Are AI and WeChat services required?

The default mock mode supports demos but does not call real AI or send WeChat notifications. Real AI needs its service key; production WeChat use needs your own AppID, Secret, domain and subscription template. This is not a ready-made hosted service.

What do the preview and checks cover?

The preview is the author’s 400×300 sample task screen, not our device photograph. Source and deployment documentation were reviewed. The README still marks device display and Mini Program UI verification as pending; we have not tested hardware either. Original project code is MIT-licensed.
