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.
the code is all at github.com. there is a platformio firmware (c++17), a rust web/worker backend, and an elm ui frontend. there is also a markdown file with a list of components involved; each “unit” probably comes in at ~20 USD for now.
