Holistic Mathematics Agency2025-07-21 Inventor's NotebookI'm making lightweight data loggers out of Raspberry Pi Pico W, ESP32, Raspberry Pi Zero 2 W as MQTT broker, and almost every sensor I find in my lab sensor bin. TIL that Last Will and Testament (LWT) is part of the MQTT protocol. It's so useful I think it must be a published design pattern for IoT.
