Blueprints

A blueprint is an automation you import with one click and fill in with your own entities and actions. Each one below asks Jev one question, or a few in one call, and runs your actions on the answer. The import button opens your Home Assistant and asks where to save it.

Every blueprint description says about how many calls a day it makes. The hold time and the cooldown inputs keep a sensor that changes often from asking more than once. What it costs turns calls into money.

Each blueprint has a test that creates the automation in a real Home Assistant, fires its trigger and checks which of your actions ran. None of them locks, unlocks, arms or opens anything.

Start from a question
