Sensor board not up after blackout
by
onOn June 12 around 9:45 there was a complete blackout in our house. After this blackout the FLM's webserver came up again and also proper heartbeats were sent. Irritatingly there were no sensor readings and so no sensor data collected until we came back on June 17 and I shortly pulled the FLM's power to hard restart it. After the restart everything worked fine again. Sadly I don't know for how long there was the power drop on June 12 causing the improper start of the sensor board. What could have caused such a condition? No correct brown-out detection, too short power drop for a brown out, but long enough to decouple it from the server board? Any other idea? Who has experienced a similar phenomenon?
