Grafana Dashboard

[vaughnlfisher]

Sorry to ask for help again

I import the json grafan file but no panels show up in the newly created dashboard. Do you think I’ve done something wrong? Any ideas?

Thanks

Of course you have created an InfluxDB database, populated by the NodeRed flow also included... I imagine that you understand the global functionning of the system:

• PoolMaster (ESP32) sends messages on MQTT topics to a MQTT broker;
• the broker transfer those messages to subscribers of the given topics, in this case the NodeRed flow;
• the flow processes the data and send measurement to the InfluxDB database;
• Grafana then periodically retrieves data from InfluxDB and display them on a dashboard. That means that you have to set up MQTT broker, Nodered server and flow, InfluxDB database and grafana. Did you do all this?
