If you have 10 portable Anthias units at a conference, you can sync them without cloud internet.
Abstract
Digital signage has traditionally relied on fixed infrastructure, limiting its application in dynamic, temporary, or mobile environments. This paper examines Screenly Anthias, an open-source digital signage platform, and evaluates its viability for portable deployments. We propose a lightweight architecture leveraging Raspberry Pi hardware, battery power, and Wi-Fi tethering to enable fully portable digital signage. The study includes a technical deployment guide, power consumption analysis, and practical use cases such as event signage, emergency information systems, and mobile retail displays. Results indicate that Screenly Anthias, with minor configuration adjustments, can operate reliably in portable mode for 6–10 hours on standard battery packs, offering a cost-effective and flexible alternative to proprietary solutions. screenly anthias portable

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.
