Quote0 Dot Screen

Quote/0 Dot Screen Controller

Overview

This skill provides control over Quote/0 electronic screen devices through the Dot Developer Platform APIs.

CRITICAL: You MUST use the provided Python scripts in the scripts/ directory for ALL operations. Do NOT attempt to make direct API calls (via curl, requests, or custom code). The scripts handle authentication, error handling, and response formatting.

Prerequisites

Check for DOT_API_KEY environment variable before any operation. If not set, guide the user to:

1. Visit https://dot.mindreset.tech/docs/service/open/get_api
2. Create an API key in the Dot. App
3. Export the key: export DOT_API_KEY=xxx
