Project description
📚 Context: vrngpb/snmpv3_agent_s3eth — firmware for a Waveshare ESP32-S3-ETH that reports a server room's temperature, water leak and door state over SNMPv3 authPriv, and takes network settings by SNMP SET with a five-minute confirm-or-revert. 01 — What the repository builds A monitoring node that sits in a server room. It reads three sensors, serves them over SNMP, and a management system collects them with SNMPv3.
