Do I need Telegraf?

Thanks… I am able to connect to the InfluxDB from grafana(same localhost) when setting up a datasource but I do not get any data.
iotawatt is on the same local network. I have tried using the hostname.domain.tld as well as the IP address with and without the port specified at the end of the URL.
I confirmed there was no data from the InfluxDB CLI
use iotawatt
Using database iotawatt
