When my Raspberry Pi 5 NAS rebooted into kernel 6.12.87, the Radxa Penta SATA HAT’s JMB585 controller failed to initialise and every disk vanished. NFS followed, and my Frigate NVR quietly stopped recording. The fix was one line in config.txt.
weewx runs exactly one station driver. I wanted the Vevor station’s data and an indoor sensor that only exists as MQTT messages from rtl_433. weewx-metadriver runs both drivers side by side, and an old MQTT driver needed a rewrite before it would work with weewx 5 and paho-mqtt 2.
A Vevor weather station that can only upload to Weather Underground, a Raspberry Pi 3 pretending to be wunderground.com on its own isolated wifi network, and weewx-interceptor catching the data. Plus the WPA2 handshake that failed nine times out of ten, and the console clock that was an hour fast.
How a Raspberry Pi 5, a cheap u-blox GPS module, and chrony turned into a home stratum-1 time server — the wiring mistakes, the serial-port gotcha nobody documents, and the PPS upgrade that took accuracy from ±50ms to ±350ns.
