Network findings: When using phone hotspot, Anthias performed synchronously. Offline mode required manual asset refresh via USB or SD card swap—acceptable for pre-planned events.
Power: The RPi 4 + 10" LCD draws 5.2W average. A 30,000 mAh (3.7V nominal → 111 Wh) delivered ~7.2 hours, matching theoretical.
Reliability: No crashes over 30 cumulative hours of looping playback. Unit B showed thermal throttling after 90 min in direct sun, mitigated by passive heatsink. screenly anthias portable
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: | Metric | Unit A | Unit B
SSH into your Pi. Run the following commands to set up an Access Point that starts automatically on boot.
sudo apt install hostapd dnsmasq
sudo systemctl unmask hostapd
sudo systemctl enable hostapd
Configure /etc/dhcpcd.conf to give the Pi a static IP (192.168.4.1). Then configure hostapd.conf for your SSID. Once rebooted, your Screenly Anthias player will broadcast its own Wi-Fi.
Pro Tip: Install watchdog so that if the Wi-Fi dongle or Pi crashes in the field, it auto-reboots. What does "Portable" actually mean for Screenly Anthias
Add a USB GPS dongle to your Pi. Script Screenly to rotate assets based on location.
| Problem | Likely Fix |
|---------|-------------|
| Screen doesn’t wake with Pi | Use a powered USB hub or check monitor’s auto-sleep settings |
| WiFi drops after moving | Install autohotspot script to auto-join known networks |
| Video stutters | Use H.264 encoded MP4 (not HEVC) on Pi 3 |
| Power bank cuts out | Some banks require >100mA load to stay on. Enable Pi’s USB boot current limit. |
