# Jev for Home Assistant

Ask [TypeSafe Jev](https://typesafe.ai) 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.

[jevclient](https://github.com/AboveColin/jevclient).



## What it does

- Questions become sensors: a probability, one of your options with its
  distribution, or a number that can land between levels. Add them in the UI,
  or in `configuration.yaml`, or both.
- Four actions answer inside an automation and return a response variable:
  `jev.noul`, `jev.choice`, `jev.score` and `jev.ask`.
- Point a question at entities, devices, areas, floors or labels in the normal
  picker and the state is built for you, so no template is needed.
- A conversation agent for Assist, so spoken commands are routed by the same model
  and counted against the same budget.
- Reports what it spends: calls, input tokens and estimated cost per day, plus a
  daily token budget that halts evaluation when it trips.
- Fifteen worked [examples](examples/), four of them pairing Jev with an LLM.
