What it is
Ask TypeSafe Jev questions about your house and get numbers back. Jev is a decision model rather than a chat model, so it answers a typed question with a probability, a choice or a score, and this integration turns each answer into an entity you can automate on.
The homepage listed on the repository, jev.cdevries.dev, puts it like this: Ask your house a typed question and get a probability, a choice or a score back as an entity. A Home Assistant integration for TypeSafe Jev.
What the README says it does
- Questions become sensors: a probability,
- Five actions, jev.noul, jev.choice,
- An AI Task entity answers
- Actions and the AI Task can look at cameras:
- A conversation agent for Assist routes
From the project’s README.
Where the decision sits
HA-Jev calls the hosted decision API rather than running its own weights. That keeps the project small and means its behaviour moves whenever the vendor ships a new model version. It also means an API key and a network round trip sit in the path of every decision.
Models it references: Jev.
How active it is
Created 2026-09-17, last pushed 2026-10-26, 82 stars and 12 forks when we read it on 2026-11-02. Everything in this category is weeks old at most, so a stale push date means something different here than it would on a mature project. Check the repository before you depend on it.
Find out what your data actually supports
We turn your historical decisions into a frozen test set, then tell you which model, which threshold, and how much of it you can safely automate.
