Home Assistant with nginx as a reverse proxy
If you run a public Home Assistant instance it is a good idea to enable SSL/TLS. The following configuration generates a certificate using letsencrypt:
services.nginx = {
recommendedProxyConfig = true;
virtualHosts."hass.your-domain.tld" = {
forceSSL = true;
enableACME = true;
extraConfig = ''
proxy_buffering off;
'';
locations."/" = {
proxyPass = "http://127.0.0.1:8123";
proxyWebsockets = true;
};
};
};
Adding postgresql support
Home-assistant supports PostgreSQL as a database backend for, among other things, its logger and history components. It's a lot more scalable and typically provides faster response times than the SQLite database, that is used by default.
Remember to make backups of your database, for home-assistant is becoming more and more stateful and has moved away from a completely declarative YAML configuration for new and core components.
services.home-assistant = {
package = (pkgs.home-assistant.override {
extraPackages = py: with py; [ psycopg2 ];
});
config.recorder.db_url = "postgresql://@/hass";
};
services.postgresql = {
enable = true;
ensureDatabases = [ "hass" ];
ensureUsers = [{
name = "hass";
ensurePermissions = {
"DATABASE hass" = "ALL PRIVILEGES";
};
}];
};
Run home-assistant from github repository
When developing home-assistant for some test dependencies additional libraries are needed. A nix-shell expression for this is available here.
Add custom lovelace modules

Add custom components
In order to install a custom component, you have to place it in /var/lib/hass/custom_components. This can be achieved using systemd tmpfiles like so (for sonoff custom component):
systemd.tmpfiles.rules = [
"C /var/lib/hass/custom_components/sonoff - - - - ${sources.sonoff-lan}/custom_components/sonoff"
"Z /var/lib/hass/custom_components 770 hass hass - -"
];
