TRMNL Content Generator

Generate HTML content for TRMNL e-ink display devices.

Prerequisites

Install the trmnl CLI to the latest version: npm install -g trmnl-cli@latest Configure a webhook plugin (one-time setup): # Add a plugin trmnl plugin add home "https://trmnl.com/api/custom_plugins/{uuid}" # Verify it's configured trmnl plugin

Quick Start Workflow

Install/update CLI: Run npm install -g trmnl-cli@latest Check plugins: Run trmnl plugin - if none, prompt user to add one Confirm device type (default: TRMNL OG, 2-bit, 800x480) Read relevant reference docs based on content needs Generate HTML using TRMNL framework classes Write HTML to a temp file and send: trmnl send --file /tmp/trmnl-content.html # Or to a specific plugin: trmnl send --file /tmp/trmnl-content.html --plugin office Minimal confirmation only - Do NOT echo content back to chat

Sending Content

From file (recommended): # Write HTML content to file first cat > /tmp/trmnl-content.html << 'EOF' <div class="layout layout--col gap--space-between"> <div class="item"> <span class="value value--xlarge value--tnums">Hello TRMNL!</span> </div> </div> <div class="title_bar"> <span class="title">My Plugin</span> </div> EOF # Send to display trmnl send --file /tmp/trmnl-content.html Validate before sending: trmnl validate --file /tmp/trmnl-content.html View send history: trmnl history trmnl history --today trmnl history --failed

Reference Documentation

Read these files as needed: FileWhen to Readreferences/patterns.mdStart here - Common plugin patternsreferences/framework-overview.mdDevice specs, e-ink constraintsreferences/css-utilities.mdColors, typography, sizing, spacingreferences/layout-systems.mdFlexbox, grid, overflow enginesreferences/components.mdTitle bar, dividers, items, tablesreferences/webhook-api.mdPayload format, troubleshootingassets/anti-patterns.mdCommon mistakes to avoid

Standard Plugin Structure

Every plugin follows this pattern: <div class="layout layout--col gap--space-between">  </div> <div class="title_bar"> <img class="image" src="icon.svg"> <span class="title">Plugin Name</span> <span class="instance">Context</span> </div> layout + layout--col = vertical flex container gap--space-between = push sections to edges title_bar = always at bottom, outside layout divider = separate major sections CRITICAL: Only ONE .layout element per view

Grid System (10-Column)

Item Component

<div class="item"> <div class="content"> <span class="value value--xlarge value--tnums">$159,022</span> <span class="label">Total Sales</span> </div> </div>

Value Typography

Always use value--tnums for numbers. ClassUsagevalue--xxxlargeHero KPIsvalue--xxlargeLarge pricesvalue--xlargeSecondary metricsvalue--tnumsRequired for numbers

Grayscale Classes

Use dithered classes, not inline colors: bg--black, bg--gray-60, bg--gray-30, bg--gray-10, bg--white text--black, text--gray-50

Data Attributes

AttributePurposedata-fit-value="true"Auto-resize text to fitdata-clamp="N"Limit to N linesdata-overflow="true"Enable overflow management

Best Practices

Use layout + title_bar structure Always value--tnums for numbers Use data-fit-value on primary metrics Use bg--gray-* dithered classes Keep payload under tier limit Minimal confirmations - just "Sent to TRMNL"
