influxdb-firehose

This repository houses the configuration for the InfluxDB + Grafana + Telegraf setup I have running to pull temperature and humidity data from esp32-sensor-reader-mqtt, air quality data from esp32-air-quality-reader-mqtt, and power usage data from powerwall-to-pvoutput-uploader.

Configuration

1. Create a .env file at the root of this repository with the following contents (the INFLUXDB_TOKEN and INFLUXDB_ORG values will be filled out after InfluxDB has been started up for the first time):

MQTT_BROKER_ADDRESS=tcp://<your-broker-address>:1883
INFLUXDB_TOKEN=""
INFLUXDB_ORG=""

2. Run docker compose up to bring all the containers up.
3. Load the InfluxDB UI at localhost:8086 and create a new user, organisation, and three buckets: weather, power, and air-quality, plus a read/write token for the bucket.
4. Set the token and organisation name in the .env file from Step 1 then restart the Telegraf container with docker compose restart telegraf.
5. Log in to the Grafana UI at localhost:3000 with the default admin/admin username and password.
6. Add a new data source for InfluxDB, set the Query Language to "Flux", and the organisation, token, and default bucket to use.
7. Optionally import the dashboard.
