InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
Which part is giving you trouble? Did you get it setup at least? Can you access the web interface? There's an option under "Schedule Wake Up" called "On Power Restore." My understanding (although I've never used this option) is that it will turn on the Pi when the battery detects power. If it's not working, I found this: https://github.com/PiSugar/PiSugar/issues/59 which might help.
