?The orb shows the sun's live position in the sky. The dot tracks the sun — above the horizon line means daytime. The countdown shows time until your next rule fires; it turns amber under one hour and red when two minutes away.

Terminus
Your automations, tied to the sun.
Terminus fires a webhook the instant the sun rises or sets — for any location on Earth, recalculated fresh every day. No cron jobs. No clocks to adjust. Just solar events, delivered automatically.
01
Choose a trigger
Sunrise or sunset. Any city on Earth. Add an offset to fire minutes before or after the exact moment.
02
Connect a webhook
Paste any HTTP endpoint — n8n, Make, Zapier, Home Assistant, or your own server. Terminus does the rest.
03
Let it run
Solar times recalculate every morning. Your automations stay accurate year-round without any maintenance.
Reading the dashboard

Live solar altitude and azimuth for your location. Altitude goes negative when the sun is below the horizon. Today's exact rise and set times update daily.
Orb — center
The dot shows where the sun sits in the sky right now. The countdown below it shows time until your next rule fires — turns amber under an hour, red under two minutes.
Rules — right
Every automation you've created. The highlighted card is next to fire. Pause a rule temporarily with ⏸, or hit "fire" to test your webhook immediately.
Footer — bottom
A live log of recent webhook deliveries with HTTP status codes. Use "Test fire" to send a real request right now and confirm your endpoint is working.
