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.
A cheap/easy solution uses a Teensy LC. Add a DIP switch and you can select one of 16 different payloads. The code is Arduino-based. I did a workshop based on this and it should still work fine. https://github.com/anyconhhv/HIDtool
