Sensor Gaps Datalog

We scan my datalog for gaps due to power outage, network outage or most likely both. We'll looking for experience with long term monitoring of aggregates. github github

See ESP8266 Datalog

Our first attempt at aggregation used a different format saved as code on an earlier version of this page now smashed into the 2024-01.log asset. revision

Gaps in sensor data for yesterday and up to present time today. A version of this code runs on a home server and is polled daily by the gaps datalog.

Gaps by day of week, hover for details. plot gallery

We remove duplicate gaps can appear in our logs since log files roll over on a GMT clock but our sampling for gaps is regular but not similarly aligned. Here for several months.

Our sensors are sampled 5000 times a day or once every 0.288 minutes. Short gaps might better be measured by counting missing samples. 0.6, 0.9 and 1.2 represent 1, 2 and 3 missing samples.
