## TRMNL BYOS (PHP/Laravel)
|
||
|
||
[](https://github.com/usetrmnl/byos_laravel/actions/workflows/test.yml)
|
||
|
||
TRMNL BYOS Laravel is a self-hostable implementation of a TRMNL server, built with Laravel.
|
||
It allows you to manage TRMNL devices, generate screens using native plugins, recipes (45+ from the [community catalog](https://bnussbau.github.io/trmnl-recipe-catalog/)), or the API, and can also act as a proxy for the native cloud service (Core).
|
||

|
||
|
||
### Key Features
|
||
|
||
* 📡 Device Information – Display battery status, WiFi strength, firmware version, and more.
|
||
* 🔍 Auto-Join – Automatically detects and adds devices from your local network.
|
||
* 🖥️ Screen Generation – Supports Plugins (even Mashups), Recipes, API, Markup, or updates via Code.
|
||
* Over 45 compatible open-source recipes are available in the [community catalog](https://bnussbau.github.io/trmnl-recipe-catalog/)
|
||
* Supported Devices / Apps: TRMNL, ESP32 with TRMNL firmware, [trmnl-android](https://github.com/usetrmnl/trmnl-android), [trmnl-kindle](https://github.com/usetrmnl/byos_laravel/pull/27), …
|
||
* 🔄 TRMNL API Proxy – Can act as a proxy for the native cloud service (requires TRMNL Developer Edition).
|
||
* This enables a hybrid setup – for example, you can update your custom Train Monitor every 5 minutes in the morning, while displaying native TRMNL plugins throughout the day.
|
||
* 🌙 Dark Mode – Switch between light and dark mode.
|
||
* 🐳 Deployment – Dockerized setup for easier hosting (Dockerfile, docker-compose).
|
||
* 🛠️ Devcontainer support for easier development.

|
||
|
||
### Hosting
|
||
|
||
Run everywhere, where Docker is supported: Raspberry Pi, VPS, NAS, Container Cloud Service (Cloud Run, ...).
|
||
For production use, generate a new APP_KEY (`php artisan key:generate --show`) and set the environment variable `APP_KEY=`. For personal use, you can disable registration (see section Environment Variables).
|
||
|
||
#### Docker Compose
|
||
Docker Compose file located at: [docker/prod/docker-compose.yml](docker/prod/docker-compose.yml).
|
||
|
||
##### Backup Database
|
||
```sh
|
||
docker ps #find container id of byos_laravel container
|
||
docker cp {{CONTAINER_ID}}:/var/www/html/database/storage/database.sqlite database_backup.sqlite
|
||
```
|
||
|
||
##### Updating via Docker Compose
|
||
```sh
|
||
docker compose pull
|
||
docker compose down
|
||
docker compose up -d
|
||
```
|
||
|
||
#### VPS
|
||
If you’re using a VPS (e.g., Hetzner) and prefer an alternative to native Docker, you can install Dokploy and deploy BYOS Laravel using the integrated [Template](https://templates.dokploy.com/?q=trmnl+byos+laravel).
|
||
It’s a quick way to get started without having to manually manage Docker setup.
|
||
|
||

#### Login
|
||
|

|
||
`admin@example.com` / `admin@example.com`, otherwise register. With environment variable `REGISTRATION_ENABLED` you can control, if registration is allowed.
|
||
|
||
### ➕ Add Your TRMNL Device
|
||
|
||
##### Auto-Join (Local Network)
|
||
|
||
1. Switch on the “Permit Auto-Join” toggle in the header. For that to work only one user can be registered.
|
||
2. New devices on your local network will be detected and added automatically when connecting to the server.
|
||
|
||
✅ This is the easiest way to connect your devices with minimal effort.
|
||
|
||
##### Manually
|
||
|
||
1. Open the Devices page:
|
||
👉 http://localhost:4567/devices
|
||
2. Click “Add New Device”.
|
||
3. Retrieve your TRMNL MAC Address and API Key:
|
||
- You can grab the TRMNL Mac Address and API Key from the TRMNL Dashboard
|
||
- Alternatively, debug incoming requests to /api/setup to determine them
|
||
|
||
|
||
### ⚙️ Configure Server for Device
|
||
|
||
#### 📌 Firmware Version 1.4.6 or Newer
|
||
|
||
* Setup device
|
||
* After entering Wifi credentials, choose "Custom Server"
|
||
* Point to the URL of your server
|
||
|
||
#### Firmware Older Than 1.4.6
|
||
|
||
If your device firmware is older than 1.4.6, you need to flash a new firmware version to point it to your server.

|
||
|
||
### ☁️ Activate fresh TRMNL Device with Cloud Proxy
|
||
|
||
1) Setup the TRMNL as in the official docs with the cloud service (connect one of the plugins to later verify it works)
|
||
2) Setup Laravel BYOS, create a user and login
|
||
3) In Laravel BYOS in the header bar, activate the toggle "Permit Auto-Join"
|
||
4) Press and hold the button on the back of your TRMNL for 5 seconds to reactivate the captive portal (or reflash).
|
||
5) Go through the setup process again, in the screen where you provide the Wi-Fi credentials there is also option to set the Server URL. Use the local address of your Laravel BYOS
|
||
6) The device should automatically appear in the device list; you can deactivate the "Permit Auto-Join" toggle again.
|
||
7) In the devices list, activate the toggle "☁️ Proxy" for your device. (Make sure that the queue worker is active. In the docker image it should be running automatically.)
|
||
8) As long as no Laravel BYOS plugin is scheduled, the device will show your cloud plugins.
|
||
|
||
###### Troubleshooting
|
||
|
||
Make sure that your device has a Developer license, you should be able to verify by calling the `https://trmnl.app/api/display` endpoint.
