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.
I'm basing it on a couple of things but for the main app/control software I'm using https://github.com/medlor/bleeding-edge-ranciliopid with an esp32 for the number of pins but also going to be referencing http://espresso-for-geeks.kalaf.net/features/pressure-profiling/ for the pump side of things.
