My system crashed this afternoon. This is the log starting with the last
successful Ftp. I had been working on my MQTT sensor code, adding some
delay to cut down on the file writes to the SD card.
My setup is an RPi 4 with an Ultimeter Station and an additional BME280
sensor connected to a Huzzah ESP8266 that publishes an MQTT payload. I have
a little Python3 program that subscribes to the MQTT and writes a file for
the file pile service. This basic set up has been working for several days,
until I restarted the MQTT based sensor, the MQTT messages are being
published OK and all looked good. I thought I heard rain and looked to my
web site and the time was 15:45 on the site, real time was about 19:00.
So my question is - did I uncover a bug or did I screw something up.
