Even 33,000 events isn't a big enough number. This Energy Meter device has 18 states that it reports on (six sets of three), so 33,000 entries is only about 1,800 entries per event type (and Hubitat sets a limit of 2,000 entries for the same event type).
For an event that reports every 10 seconds, a full 2,000 entries (the maximum allowed) is only 5.5 hours. That's not enough back-up; I want at least 24 hours.
I reconfigured my network yesterday and the process that reads the websocket hung and stopped recording events. I didn't notice until 18 hours later. I used that huge URL nonsense to grab the entire event log for each of the devices (Feature Request: A button to download all the events), but for the events that repeat every 10 seconds I lost 12.5 hours of entries because I was only permitted 2,000 (5.5 hours) of them to be saved.
Alas, Hubitat doesn't let me do what I want, which is to save 24 hours of each event, nor does it let me save different numbers of events depending on the frequency of reporting. For events that repeat hourly, 2,000 entries is an unnecessary 2,000 hours (83 days). For sensor logs that repeat every 10 seconds, 2,000 is not nearly enough.
