I am looking for more information on how to use hivemq-sparkplug-influxdb-extension using the free Hivemq cloud.

Any links would be appreciated.

Hello @Neta,

Welcome to our community forum.

HiveMQ Cloud free/PayG cluster does not offer this extension. With HiveMQ cloud Dedicated cluster, you can install and configure this extension(or more extensions). To find out all details of the offer and pricing detail at: HiveMQ Cloud - Free Fully Managed MQTT Platform .
In case you are interested and looking for more details about the Dedicated cluster, feel free to reach us via the “Contact us” button under the Dedicated block.

Kind regards,
Sheetal from HiveMQ team
