It aims to simplify the development for manufacturers and increase compatibility for the consumers, enabling communication across smart home devices, mobile apps, and cloud services.
Lyra is based on the Silicon Labs EFR32BG22 SoC (Wireless Gecko Series 2) and does not support the development of Matter applications.
