hamm v0.0.4

HAMM - Home Assistant configuration Manager (M)

HAMM aims to make Home Assistant configuration testable, repeatable and reusable. It provides tools to set up multiple independent HA instances for testing and production deployment and managing configuration from a single source of truth which can be stored in a version control system like GIT.

Prerequisites

1. HAMM only works in UNIX-like systems like Linux or BSD. MS Windows users should use WSL2.
2. Node.js version 16 or above is required. If you need to use multiple versions of Node.js on your machine, use nvm.
3. Git should also be installed on your machine.

Usage

Installation

There is no need to install HAMM manually. Just run the commands through npx utility which is part of Node.js.

Create a new project

First you need to create a new project. To do that run

$ npx hamm create path/to/project

Replace path/to/project with a path to a directory which should contain project files. The directory will be created for you.

Project structure

hamm.json contains basic configuration for the project.

env directory contains environment specific configuration. Only two environments are supported at the moment: dev and prod.

src contains your Home Assistant configuration files.

overlays contains configuration files specific to each environment which will be written over src contents during build process.

Building the project

To build the project for dev environment run

$ npx hamm build dev

To build the project for prod environment run

$ npx hamm build prod

Results of the build process can be found in build directory.

Watch mode

HAMM supports watch mode. In watch mode the project will be auto-rebuilt every time changes are saved to disk.

$ npx hamm watch dev

Clean

To clean the build directory, run

$ npx hamm clean [ENVIRONMENT]

Where ENVIRONMENT can be either dev, prod, or not present. If ENVIRONMENT is not present, the whole build directory will be removed.

Debug

Debug command will print out current HAMM state and its configuration.

$ npx hamm debug [ENVIRONMENT]

Where ENVIRONMENT can be either dev, prod, or not present. If ENVIRONMENT is not present, environment configuration output will be skipped.
