Expanding Z-Wave: Multi-Protocol Innovation and Specification Evolution
summary
Concrete claims and build details: a Silicon Labs EFR32ZG28 SOC runs a sub‑GHz Z‑Wave radio plus 2.4 GHz BLE and supports either switched multi‑protocol (A/B bootloader for phone OTA updates) or dynamic multi‑protocol (time‑sliced radio windows with latency and power tradeoffs). Specification changes include S2V2 encryption, a Wake on Event batteryless device type, and new User Credentials command classes. Z‑Wave Long Range uses a star topology at about 100 kbps, supports thousands of devices, and has demos and a works‑with event scheduled.
