It is a bit lower on my prio list, and I probably won’t try to tackle it until Enable binding to store historic states by altaroca · Pull Request #3000 · openhab/openhab-core · GitHub has been merged - and then some InfluxDB support as well [influxdb] Partial ModifiablePersistenceService support by seime · Pull Request #12935 · openhab/openhab-addons · GitHub (waiting for the previous one).
So feel free to add a reaction (not comment) to Enable binding to store historic states by altaroca · Pull Request #3000 · openhab/openhab-core · GitHub
