teahouse

Teahouse is a home automation orchestrator inspired by The Elm Architecture (TEA) https://guide.elm-lang.org/architecture/

In teahouse, instead of Html the "view" is your house :)

For a taste, take a look at my house!

story

Things like Home Assistant look pretty cool, but they end up being programming in YAML. YAML configuration is good in that its declarative, but ultimately kinda awkward to work with, especially since I know how to program for reals.

Elm and its architecture has a pleasant sort of middle ground: its quite data driven, but you express the data using functions.

So I decided to try to work up something like TEA, but in Typescript, and a lot less pure.

intro

What happens within the Elm teahouse program though? It always breaks into three parts:

Model — the state of your application house.

View House — a way to turn your state into HTML your house.

Update — a way to update your state based on messages.

Model

Model's whatever you like... generally nested records.

House

A function which takes the model and outputs a tree of Nodes.

Leaf nodes are Home Automation devices. Devices can produce Messages, which are dispatched back into the update function.

Update

A function which takes a message and the model and returns a new model and a command.
