+# Remote Two/3 TypeScript Integration Driver Example
+
+This project implements a simple integration driver in TypeScript for the [Unfolded Circle Remote Two and 3 devices](https://www.unfoldedcircle.com/)
+using the [UC Integration-API Node.js API wrapper](https://github.com/unfoldedcircle/integration-node-library).
+
+It can be used as a quick start template for writing custom integration drivers.
+
+This example creates three sample entities: a light, a media-player, and a button.
+
+## Usage
+
+This simple example loads the driver configuration file [src/light-driver.json](src/light-driver.json) from the same
+directory as the driver file.
+
+Logging in the `@unfoldedcircle/integration-api` package is directed to the [debug](https://www.npmjs.com/package/debug)
+module. To let the UC API wrapper output anything, run your integration driver with the `DEBUG` environment variable set
+like `DEBUG=ucapi:*`.
+
+See [API wrapper logging](https://github.com/unfoldedcircle/integration-node-library?tab=readme-ov-file#logging) for
+more information.
+
+Install dependencies and development tools (like the tsc TypeScript compiler):
+
+```shell
+npm install
+```
+
+Compile TypeScript:
+
+```shell
+npm run build
+```
+
+Start the driver:
+
+```shell
+DEBUG=ucapi:* node dist/src/light.js
+```
+
+The driver is now discoverable by the Remotes, or can be manually registered in the Simulator.
+
+A full walk-through is described in the next section.
+
+## Development Guide
+
+### Development Environment
+
+- macOS, Linux or Windows are all suitable for developing an integration driver.
+- A modern IDE with TypeScript support is not required but highly recommended, for example Visual Studio Code or
+  JetBrains WebStorm.
+- [Node.js](https://nodejs.org/) version 20.16 or newer
+- Node.js API wrapper for the UC Integration API. This is an NPM package to quickly use the WebSocket Integration-API.
+
+```shell
+npm install @unfoldedcircle/integration-api
+```
+
+#### Remote-Core Simulator
+
+If you have a Remote Two or Remote 3 device, then you can directly use the physical devices to develop an integration
+driver. Otherwise, the [Remote-Core Simulator](https://github.com/unfoldedcircle/core-simulator) provides a device
+simulation for most features.
+
+- **Container runtime**: the [Remote-Core Simulator](https://github.com/unfoldedcircle/core-simulator) is distributed as
+  a container image.
+  This requires a container runtime on your machine, for example Docker or Podman.
+
+- **Remote-Core Simulator**: Download the [Remote-Core Simulator](https://github.com/unfoldedcircle/core-simulator).
+  Change into the `./docker` directory and run the pre-configured Docker Compose services:
+
+Run:
+
+```shell
+docker compose up
+```
+
+You should see messages similar to this in the terminal:
+
+```
+docker compose up

+```
+
+Open <http://localhost:8080/configurator>` in a browser to login to the Web-Configurator of the Remote Two Core Simulator:
+
+Enter the pin, then click "Unlock".
+See [Simulator documentation](https://github.com/unfoldedcircle/core-simulator?tab=readme-ov-file#user-accounts-1) for
+the pin.
+
+![configurator_1](img/simulator-login.png)
+
+After unlocking the Web-Configurator, you are greeted with the following page:
+
+![integrations_n_docks](img/simulator-home.png)
+
+Go to "Integrations & docks" to see added integrations. Initially, only the "Home Assistant" integration should appear
+(which is part of the Docker Compose setup):
+
+![integrations_n_docks_2](img/simulator-intg-docks.png)
+
+#### REST client
+
+The Simulator requires to manually register integration drivers with the Core-API. Automatic service discovery is not
+working inside the container image.
+
+This can be done with curl on the command line, or with a visual REST client like [Postman](https://www.postman.com) or
+[Bruno](https://www.usebruno.com/).
+
+This guide will use Postman and show the corresponding curl requests.
+The prepared [Remote Two Core-API Postman collection](https://github.com/unfoldedcircle/core-api/blob/main/core-api/rest/remote-core_rest-api.postman_collection.json)
+helps you get started.
+
+#### Core-API Authentication
+
+Most Core-API endpoints require authentication. Credentials can be provided for each request or through a cookie based
+session login.
+
+- The Postman collection is configured to use the session based login.
+- When working with curl, it's usually easier to set the credentials in each request.
+
+To log in with admin rights, use the `/auth/login` endpoint:
+
+```json
+{
+  "username": "{{apiUsername}}",
+  "password": "{{apiPassword}}"
+}
+```
+
+![Postman login](img/postman-login.png)
+
+- username: `web-configurator`
+- password: same pin as when logging in to the web-configurator
+
+It's recommended to store credentials in the "current value" of a variable. If you have multiple Remote devices or use
+the Simulator with a real device, use environments to quickly switch between different servers.
+
+When using curl, use the `--user $USER:$PASSWORD` parameter.
+
+### Start Integration Driver
+
+Compile and start the driver:
+
+```shell
+npm run build
+DEBUG=ucapi:* node dist/src/light.js
+```
+
+The terminal should show messages similar to:
+
+```
+DEBUG=ucapi:* node light.js
+  ucapi:debug Driver info loaded +0ms
+  ucapi:debug Starting mdns advertising +2ms
+  ucapi:info Driver is up: simulated_light, version: 1.0.0, listening on: 0.0.0.0:9988 +0ms
+  ucapi:debug Light entity created with id: my_unique_light_id +1ms

+  ucapi:debug MediaPlayer entity created with id: test_mediaplayer +0ms
+  ucapi:debug ENTITIES(available): Entity added: test_mediaplayer +0ms
+```
+
+Leave this terminal running, now it's time to register the driver in the Simulator.
+
+### Driver Registration
+
+In Postman, send the `/integrations/driver/registerIntegrationDriver` request, adjusted to your driver and network settings.
+
+‼️ Replace `$IP` in `driver_url` with the IP address where your integration driver is running. This must be a reachable
+IP address from the container network. It is usually the IP address of the network interface connected to your router.
+
+![register_driver](img/postman-register-driver.png)
+
+Curl request:
+
+```shell
+curl 'http://localhost:8080/api/intg/drivers' \
+--user web-configurator:$PIN \
+--header 'Content-Type: application/json' \
+--data-raw '{
+  "driver_id": "simulated_light",
+  "version": "1.0.0",
+  "min_core_api": "1.0.0",
+  "name": { "en": "Simulated light driver", "de": "Simulierter Licht-Treiber" },
+  "icon": "custom:my_driver_icon",
+  "description": { "en": "A simple demo integration with a simulated light entity." },
+  "driver_url": "ws://$IP:9988",
+  "developer": {
+    "name": "John Doe",
+    "email": "[email protected]",
+    "url": "https://www.unfoldedcircle.com"
+  },
+  "home_page": "https://www.unfoldedcircle.com",
+  "release_date": "2024-11-04"
+}'
+```
+
+If successful, you'll see a new message in the terminal when the Simulator communicates the integration driver:
+
+```
+  ucapi:info [::ffff:172.16.16.102:47616] WS: New connection +434ms
+  ucapi:msg [::ffff:172.16.16.102:47616] <-  {"kind":"resp","req_id":0,"code":200,"msg":"authentication","msg_data":{}} +0ms
+```
+
+After successful registration the driver appears in the Web-Configurator:
+
+![my_driver](img/simulator-registered-driver.png)
+
+Click on the driver to start the setup. Select all available entities, and finish setup.
+
+![add_entities](img/simulator-add-entities.png)
+
+The configured entities will produce new log messages in the driver terminal:
+
+```
