OpenEPaperLink is an open-source alternative firmware and 802.15.4-based protocol for repurposing commercial electronic shelf labels (e-paper tags) as custom wireless displays. It consists of tag firmware and ESP32-based access point firmware, with a web interface and Home Assistant integration for driving display content.
Use cases
- turn electronic shelf labels into custom e-paper displays
- build a DIY e-ink dashboard with ESP32 access point
- show Home Assistant sensor data on e-paper tags
- repurpose store price tags for home automation
- create low-power wireless e-paper signage
- flash custom firmware onto ZBS243-based shelf labels
When to choose
- you want an open, self-hosted alternative to proprietary ESL systems
- you already own compatible electronic shelf labels and an ESP32
- you need extremely low-power (µA-level) wireless e-paper displays
- you use Home Assistant and want tags as integrated devices
When to avoid
- you need commercial/production deployment - the license is CC BY-NC-SA (non-commercial)
- you want plug-and-play without flashing hardware or building access points
- you need high-bandwidth image streaming - transfers are ~5kB/s
- you require guaranteed real-time updates - check-in latency is 40+ seconds
