What is dot-eprint?
The dot-eprint tool is a specialized skill designed to interface with Dot. electronic paper displays through the mindreset.tech API. By incorporating this into your environment via Openclaw Skills, you can automate the delivery of text notifications, signatures, and custom images directly to your low-power screen. It serves as a bridge between your local data and the physical hardware, ensuring your e-ink device remains a dynamic part of your workflow.
This skill handles the technical complexities of authentication, image dithering, and content slot management. Whether you are displaying real-time metrics or simple messages, dot-eprint provides a reliable way to interact with your IoT devices using standard web protocols and Openclaw Skills architecture.
dot-eprint Use Cases
- Sending real-time text notifications and reminders to a desk-bound e-ink screen.
- Pushing custom-processed photos or graphics using advanced dithering for e-paper clarity.
- Checking device health metrics like battery percentage and WiFi signal strength remotely.
- Managing display loops and switching between content slots programmatically.
- Automating personal dashboard updates using Openclaw Skills for persistent information display.
How dot-eprint Works
- The skill verifies the presence of DOT_API_KEY and DOT_DEVICE_ID to establish a secure connection.
- It communicates with the Dot. cloud API endpoint using authenticated HTTP requests.
- For text updates, it formats JSON payloads including titles, messages, and optional signatures or icons.
- For image updates, it utilizes local ImageMagick tools to resize and convert graphics into e-ink compatible base64 data.
- The API processes the request and updates the hardware screen, returning a status code for confirmation.
- The skill interprets response data to provide the user with clear feedback on the success of the operation.
dot-eprint Setup
To use this skill with Openclaw Skills, you must configure your environment and local dependencies:
# 1. Set your credentials (obtained from the Dot. App)
export DOT_API_KEY="your_api_key_here"
export DOT_DEVICE_ID="your_device_id_here"
# 2. Install ImageMagick for image processing capabilities
# For macOS users:
brew install imagemagick
# For Linux users:
sudo apt install imagemagick
dot-eprint Data Schema & Taxonomy
The skill interacts with the Dot. API using structured metadata and returns comprehensive device information.
| Attribute | Type | Description |
|---|---|---|
| status.battery | String | Current power level (e.g., "50%") or "Charging" |
| status.wifi | String | Signal strength measured in dBm (e.g., "-62 dBm") |
| renderInfo.current | Array | List of images currently being displayed |
| taskKey | String | Unique identifier for specific content slots |
| ditherType | Enum | Algorithm used for image rendering (DIFFUSION, ORDERED, NONE) |
All content pushed via Openclaw Skills can be assigned a taskKey to allow for targeted updates of specific slots on the device.
dot-eprint Advanced Features
- Multi-algorithm dithering support including Floyd-Steinberg and Stucki for superior e-ink image quality.
- Intelligent image preprocessing that automatically scales and centers graphics to the native 296x152 resolution.
- Content slot management via Openclaw Skills allowing users to update 'fixed' or 'loop' content types independently.
- Signature and Icon support to brand text messages with custom logos or base64 icons.
- Remote content navigation to trigger screen refreshes or jump to the next item in a display queue.
