+This document provides the necessary steps for installation of TeslaMate on any system that runs Docker. You run NixOS? We got you covered, see [NixOS install](nixos.md). For a walkthrough that provides the necessary steps for manual installation see [Manual installation](debian.md).
 
 This setup is recommended only if you are running TeslaMate **on your home network**, as otherwise your Tesla API tokens might be at risk. If you intend to expose TeslaMate directly to the internet check out the [advanced guides](../guides/traefik.md).

+title: NixOS install
+sidebar_label: NixOS
+---
+
+This document provides the necessary steps for installation of TeslaMate on [NixOS](https://nixos.org/).
+
+This setup is recommended only if you are running TeslaMate **on your home network**, as otherwise your Tesla API tokens might be at risk. If you intend to expose TeslaMate directly to the internet use a secure connection such as a VPN, Cloudflare Tunnel, Tailscale, Zero Tier and a reverse proxy like [Caddy](https://nixos.wiki/wiki/Caddy).
+
+## Requirements
+
+- NixOS _(if you are new to NixOS, see [NixOS getting started](https://nixos.org/learn/))_
+- A Machine that's always on, so TeslaMate can continually fetch data
+- At least 1 GB of RAM on the machine for the installation to succeed. It is recommended to have at least 2 GB of RAM for optimal operation.
+- External internet access, to talk to tesla.com
+
+## Instructions
+
+We provide a flake module that can be used to install TeslaMate on NixOS. To use it, you need to have Nix flakes enabled. If you don't have them enabled yet, follow the [NixOS documentation](https://nixos.wiki/wiki/Flakes).
+
+The options for the module are documented in the [module.nix](https://github.com/teslamate-org/teslamate/blob/48fb4fa2675ed742bf1b125a784dbbbcb1aceb24/nix/module.nix).
+
+In the `inputs` section of your flake add:
+
+```nix
+teslamate.url = "github:teslamate-org/teslamate/main";
+```
+
+If you would like to pin to a specific version, you can do so for example like this:
+
+```nix
+teslamate.url = "github:teslamate-org/teslamate?rev=c37638b320e0beea97c5d51fea51cd9fdbd07ce0"; # v2.0.0
+```
+
+If you have a MCU2 upgraded car, you can use the following URL instead to get the latest version of TeslaMate that supports MCU2 upgraded cars:
+
+```nix
+teslamate.url = "github:teslamate-org/teslamate/mcu2-upgraded-cars";
+```
+
+To enable the TeslaMate service, your config could look like this (note: this will conflict with any existing PostgreSQL/Grafana servers, because NixOS modules do not support multiple instances).
+
+```nix
+{
+  config,
+  lib,
+  inputs,
+  ...
+}:
+{
+imports = [ inputs.teslamate.nixosModules.default ];
+
+config = services.teslamate = {
+      enable = true;
+      secretsFile = "/run/secrets/teslamate.env"; # you can use agenix for sure: config.age.secrets.teslamateEnv.path;
+      # the secrets file must contain at least:
+      #  - `ENCRYPTION_KEY` - encryption key used to encrypt database
+      #  - `DATABASE_PASS` - password used to authenticate to database
+      #  - `RELEASE_COOKIE` - unique value used by elixir for clustering
+      autoStart = true;
+      listenAddress = "127.0.0.1";
+      port = 4000;
+      virtualHost = "$[your-domain]";
+      urlPath = "/";
+
+      postgres = {
+        enable_server = true;
+        user = "teslamate";
+        database = "teslamate";
+        host = "127.0.0.1";
+        port = 5432;
+      };
+
+      grafana = {
+        enable = true;
+        listenAddress = "127.0.0.1";
+        port = 3000;
+        urlPath = "/";
+      };
+
+      mqtt = {
+        enable = true;
+        host = "127.0.0.1";
+        port = 1883;
+      };
+    };
+}
+```
+
+If you want to use the TeslaMate web interface via a reverse proxy, you can use the following snippet if you have already Caddy service running:
+
+```nix
+{
+    services.caddy.virtualHosts."[your-sub-domain for TeslaMate]" = {
+      useACMEHost = "[your-baseDomain]";
+      extraConfig = ''
+        reverse_proxy http://127.0.0.1:4000
+      '';
+    };
+
+    services.caddy.virtualHosts."[your-sub-domain for grafana]" = {
+      useACMEHost = "[your-baseDomain]";
+      extraConfig = ''
+        reverse_proxy http://127.0.0.1:3000
+      '';
+    };
+}
+```
