Today I spent some time with the script and added a version which seems to work with openhab 3.3 and InfluxDB 2.4
I’ve forked the repository from @christoph_wempe and added a new script and cfg for use with InfluxDB 2.4. You can find it here:
(Sorry, if I’ve made something wrong with GitHub, it’s my first fork/repo 
)
For me it works fine, maybe my version helps someone else…
