Screenly Anthias: The Power of Open-Source Digital Signage in a Portable Package

In the world of digital signage, the leap from "complex industrial setup" to "plug-and-play simplicity" has been a long time coming. For years, Screenly Anthias (the open-source version of the popular Screenly software) has been the go-to for DIY enthusiasts and small businesses. But as the need for mobile displays, pop-up shops, and temporary events grows, the concept of a "portable" Anthias setup has become the ultimate game-changer.

Whether you are a trade show exhibitor, a food truck owner, or a corporate presenter, here is everything you need to know about making Screenly Anthias portable. What is Screenly Anthias?

Formerly known as Screenly OSE (Open Source Edition), Anthias is a free, powerful digital signage player designed specifically for the Raspberry Pi. It allows users to turn any screen into a dynamic display capable of showing: High-definition videos Static images Live web pages and dashboards

Because it is lightweight and runs on ARM-based hardware, it is the perfect candidate for a mobile, "display-in-a-box" solution. Why Go Portable?

Traditional digital signage is usually bolted to a wall and hardwired to a local network. A portable Anthias rig breaks these chains. Key use cases include:

Trade Shows: Set up a stand-alone kiosk in minutes without worrying about venue Wi-Fi.

Pop-up Retail: Use a battery-powered screen to show menus or daily specials.

Educational Workshops: Move your presentation display from room to room without re-configuring cables. Building Your Portable Anthias Rig: The Hardware

To make Anthias truly portable, you need to think beyond the Raspberry Pi. Here’s the "mobile kit" list: 1. The Brain: Raspberry Pi 4 or Zero 2 W

The Raspberry Pi 4 offers the best performance for video, but if you want ultimate portability and low power consumption, the Pi Zero 2 W is incredibly compact. 2. The Screen: Portable HDMI Monitors

Modern 15.6-inch portable monitors are USB-C powered and incredibly thin. Look for one with a built-in kickstand. 3. Power: High-Capacity Power Banks

Since you won't always be near a wall outlet, a power bank with Power Delivery (PD) is essential. A 20,000mAh battery can often power both a Raspberry Pi and a small portable monitor for several hours. 4. Connectivity: Mobile Hotspots

Anthias requires a network to manage assets. By configuring your Pi to automatically connect to your phone’s mobile hotspot, you can update your screen content from anywhere via the web interface. Setting Up Screenly Anthias for Mobility Step 1: The Installation

Flash the Anthias image onto a high-quality microSD card. Once booted, Anthias creates its own Wi-Fi access point. Connect to it, tell it your mobile hotspot credentials, and your "portable" link is established. Step 2: Local Asset Management

One of Anthias's strengths is its ability to cache content. Once you upload your videos or images, they live on the SD card. This means even if you lose your cellular signal in the middle of a convention center, your signage keeps running without a hitch. Step 3: Enclosure and Protection

For a truly professional look, consider a 3D-printed case that mounts the Raspberry Pi directly to the back of the portable monitor. This creates a single, unified unit that fits into a laptop bag. Tips for Success

Heat Management: If your Pi is tucked behind a monitor, ensure it has a heatsink or a small fan. screenly anthias portable

Setting up Screenly Anthias is incredibly straightforward, even for those without deep Linux experience. Step 1: Prepare the Raspberry Pi Insert your MicroSD card into your computer. Download and open the Raspberry Pi Imager tool. Choose Raspberry Pi OS (64-bit) as the operating system. Select your SD card and click write. Step 2: Install Screenly Anthias

Once your Raspberry Pi boots up and is connected to the internet, open the terminal and run the official Anthias installation command: bash <(curl -sL https://githubusercontent.com) Use code with caution.

The installer will automatically download all necessary Docker containers and dependencies. This process can take anywhere from 15 to 30 minutes depending on your internet speed. Step 3: Access the Management Web File

Once the installation finishes, the terminal will display an IP address.

Connect your laptop or smartphone to the same Wi-Fi network as the Raspberry Pi. Type the provided IP address into your web browser.

You will be greeted by the Screenly Anthias dashboard, where you can upload assets and schedule playlists. Best Practices for Mobile Digital Signage

Running digital signage on the go presents a unique set of challenges. Follow these best practices to ensure your portable display runs smoothly:

Load Assets Locally: While Anthias can display live websites, cellular hotspots at crowded trade shows are notoriously unreliable. Upload your videos and images directly to the device so they play flawlessly offline.

Optimize Video Files: Large, uncompressed video files will drain your battery faster and may cause stuttering. Encode your videos to H.264 MP4 format at 1080p resolution for the best balance of quality and performance.

Use Static IP or Hotspot Naming: If you need to change assets on the fly, set your smartphone as a mobile hotspot with a saved SSID. Your Raspberry Pi will automatically connect to it wherever you are, allowing you to access the Anthias web interface immediately.

Mind the Thermals: Raspberry Pi boards can get hot when decoding continuous HD video. If you are using your portable rig outdoors or in a case, ensure it has proper heat sinks or a small cooling fan. Common Use Cases

Where can you actually use a Screenly Anthias portable setup? The possibilities are virtually endless:

Trade Show Booths: Run product loops, promotional videos, and digital brochures right on your display table without paying the venue's exorbitant electricity and TV rental fees.

Food Trucks: Mount a portable screen to the side or window of your truck to display dynamic, easily updateable digital menus. Why: Screenly Anthias is optimized for ARM architecture

Real Estate Open Houses: Place a battery-powered screen on a kitchen counter displaying property highlights, local school data, and agent contact info.

Pop-Up Retail: Attract foot traffic to temporary physical setups with bright, moving digital art and discount advertisements.

If you need help tailoring this setup to your specific needs, let me know. Tell me:

I can give you exact hardware recommendations or configuration tweaks based on your situation.

The Core Components

1. The Compute Unit: Raspberry Pi 4 or 5

  • Why: Screenly Anthias is optimized for ARM architecture.
  • Recommendation: Raspberry Pi 4 (4GB RAM). The Pi 5 works, but consumes more power. The Pi 4 is the "sweet spot" for stability and battery life.
  • Storage: 32GB or 64GB MicroSD card (High Endurance recommended).

2. The Power Source: USB-C Power Bank (PD Standard)

  • The Challenge: A standard Raspberry Pi needs 5V/3A (15W). A monitor needs 12V–19V.
  • The Solution: A 20,000mAh – 50,000mAh Power Delivery (PD) battery pack that outputs 12V or 15V via USB-C.
  • Top Picks: Baseus Blade (100W), OmniCharge, or Anker PowerHouse (if you want AC outlets).
  • Math: A Pi 4 + 15" monitor consumes roughly 15–20W. A 100Wh battery (roughly 27,000mAh) will run this for 5–6 hours.

3. The Display: Portable USB-C Monitor

  • Gone are the days of huge CRT TVs. For portability, use a 14-inch to 17-inch USB-C monitor (ASUS ZenScreen or Arzopa).
  • Why USB-C? Many modern portable monitors accept power and video over a single USB-C cable. This reduces cable clutter.
  • Note: The Raspberry Pi 4’s USB-C port is for power only. You will still need an HDMI cable from the Pi to the monitor. However, the monitor can be powered by the same battery pack.

4. The Network: Onboard Wi-Fi Hotspot

  • The default Screenly Anthias setup expects a local network. To make it portable, the Pi must become its own network.
  • Setup: Configure the Raspberry Pi to act as a Wi-Fi Access Point (AP). You can do this using hostapd and dnsmasq.
    • SSID: "Anthias-Portable"
    • Password: "signage123"
  • Access: You connect your iPad or Laptop to this "Anthias-Portable" network, type http://screenly.local (or the Pi's static IP: 192.168.50.1), and upload new assets instantly.

5. The Case: Rugged or Rackmount

  • Pelican Case (or Harbor Freight Apache case): Cut foam to hold the Pi, the battery pack, the monitor, and the cables.
  • VESA Mount: Attach the Pi and battery to the back of the monitor using Velcro or 3D-printed brackets so the whole unit is one slab.

Step 4: Running Your Portable Signage

  1. Power on the power bank → monitor wakes → Pi boots (90 seconds).
  2. On your phone, connect to the Pi’s WiFi hotspot (or join the venue’s WiFi if you preconfigured it).
  3. Open http://raspberrypi.local in a browser.
  4. Start/stop playlists, upload emergency messages, or change schedules.

2. Background

Part 2: Defining "Portable" in Digital Signage

What does "Portable" actually mean for Screenly Anthias?

It is not an official product variant (there is no "Anthias Portable Edition" download). Instead, "Screenly Anthias Portable" refers to a custom hardware configuration that allows you to run your digital signage without relying on external power outlets, hotel Wi-Fi, or permanent mounts.

A true portable setup must achieve three things:

  1. Power Independence: Run for 6–12 hours without a wall plug.
  2. Network Independence: Operate offline or via a self-healing local hotspot.
  3. Physical Durability: Be packable into a flight case or backpack.

8. Conclusion

Screenly Anthias, originally designed for fixed digital signage, can be effectively repurposed for portable deployments with modest hardware and software adjustments. Our prototypes demonstrate runtime from 7–10 hours, offline operation, and rapid setup. The open-source nature allows customization not possible with commercial alternatives. For events, fieldwork, and mobile retail, Anthias on Raspberry Pi offers a practical, low-cost portable signage solution.
