Using Erlang Alarms for Device Recovery at Scale

In this video, Frank Hunleth, the creator of the Nerves framework, explores the use of Erlang alarms as a mechanism for enhancing the robustness and recovery capabilities of devices. He shares practical insights gained from years of experience at SmartRent, where they faced various device failure scenarios. Hunleth emphasizes the need for devices to autonomously recover from failures at scale and explains how the open-source alarmist library aids in this endeavor. The presentation covers the relationship between Erlang's fault tolerance, the foundational capabilities of Nerves, and additional strategies for improving device recovery based on real-world experiences.
