A C++20 library for parsing DLMS/COSEM push telegrams from electricity meters. It is designed for embedded and integration-heavy environments such as ESPHome
AES67 / RAVENNA audio-over-IP for the ESP32-P4 — hardware-PTP-synced RTP audio (L16/L24/L32/AM824), SAP/SDP discovery, ISR-driven I2S, sub-millisecond latency. Interop-tested against Merging SIENNA and the aes67-linux-daemon.
This is an ACME client for ESP (ESP32, etc) devices, so your IoT can fetch their own certificate for secure communication. ACME is a protocol (see <a href="https://tools.ietf.org/html/rfc8555">RFC8555</a>) for automatic certificate management. Sites such as letsencrypt.org allow you to obtain free (no charge) certificates in an automated way using the ACME protocol.
