I have been searching for a solution to this problem also for a few days. These posts are the best post I have found to exactly describe the issue. The objective is too direct Grafana to port 80 so that Dataplicity will send grafana through its worm hole.
Using dataplicity wormhole, grafana and influxdb on R Pi 4 to log and display data using Python and Grafana app under R Pi OS.
One does everything needed according to documentation but not only does Grafana not work with Dataplicity Wormhole on Port 80 it does not even work at all into localhost locally.
A soltion woild be brilliant for Raspberry Pi (R Pi) data logging applications as one could send data to influxdb and then graph it with Grafana and view from anywhere using Dataplicity Wormhole.
Help Please.
