What it is
A Home Assistant integration that turns TypeSafe Jev questions about your home into sensors and automation actions, for people who want typed, probabilistic answers rather than chat.
How it uses Jev
Jev answers typed questions (noul, choice, score) about a state built from entities, devices, areas, floors or labels. Results become sensors or action response variables like is_true, choice, score and confidence, which automations act on.
Primitives:choicescorenoul
Technique worth stealing
Attach background facts to the question rather than the state, and require a confidence bar before acting.
Try it
Install via HACS as a custom repository, restart Home Assistant, then add the Jev integration with your API key.
Evidence
Each line is one question put to Jev about the README. ≥ 0.60 reads as yes, ≤ 0.40 as no; in between Jev is not making a call.
