And there is more to it than that, Influx V2 does not directly support the original InfluxQL queries, you need to setup a DBRP mapping which basically allows you to talk to Influx v2 as if it was v1.
Found my original post explaining it with links to the docs: Influxdb2 and HE integration - #10 by jtp10181
Guess I need to work on converting all my dashboards back to InfluxQL
