How to run the Prometheus, Exporter and Grafana using docker-compose

  1. Go to docker-compose folder: cd docker-compose

  2. Update .env file with two mandatory parameters:

    • PROMETHEUS_ENABLED - true (or 1) if you want to enable integration with Prometheus. Default value is false
    • EXPORTER_TYPE - the type of exporter you'd like to use. Possible values: rest and mqtt. Default value is rest.

    If EXPORTER_TYPE=rest is selected, then provide values for the following parameters:

    • ECOFLOW_ACCESS_KEY - the access key from the Ecoflow development website
    • ECOFLOW_SECRET_KEY - the secret key from the Ecoflow development website

    If EXPORTER_TYPE=mqtt is selected, then provide values for the following parameters:

    • ECOFLOW_EMAIL - your email address that you use to log in to the Ecoflow mobile app
    • ECOFLOW_PASSWORD - your ecoflow password
    • ECOFLOW_DEVICES - the list of devices serial numbers separated by comma. For instance: SN1,SN2,SN3. Instead of ECOFLOW_DEVICES you can specify ECOFLOW_DEVICES_PRETTY_NAMES which will also work. You can specify both parameters if you wish.

  3. (OPTIONALLY) Update other variables if you need to:

    • METRIC_PREFIX: the prefix that will be added to all metrics. Default value is ecoflow. For instance metric bms_bmsStatus.minCellTemp will be exported to prometheus as ecoflow.bms_bmsStatus.minCellTemp. With default value ecoflow you can use Grafana Dashboard with ID 17812 without any changes.
    • SCRAPING_INTERVAL - scrapping interval in seconds. How often should the exporter execute requests to Ecoflow Rest API in order to get the data. Default value is 30 seconds. Align this value with docker-compose/prometheus/prometheus.yml
    • MQTT_DEVICE_OFFLINE_THRESHOLD_SECONDS - the threshold in seconds which indicates how long we should way for a metric message from MQTT broker. Default value: 60 seconds. If we don't receive message within 60 seconds we consider that device is offline. If we don't receive messages within the threshold for all devices, we'll try to reconnect to the MQTT broker (there is a strange behavior that MQTT stop sends messages if you open Ecoflow mobile app and then close it).
    • ECOFLOW_DEVICES_PRETTY_NAMES - the key/value map of custom names for your devices. Key is a serial number, value is a device name you want to see in Grafana Dashboard. It's helpful to see a meaningful name in Grafana dashboard instead of a serial number. Example: ECOFLOW_DEVICES_PRETTY_NAMES={"R33XXXXXXXXX":"My Delta 2", "R33YYYYY":"Delta Pro backup"}
    • DEBUG_ENABLED - enable debug log messages. Default value is "false". To enable use values true or 1
    • GRAFANA_USERNAME - admin username in Grafana. Default value: grafana. Can be changed later in Grafana UI
    • GRAFANA_PASSWORD - admin password in Grafana. Default value: grafana. Can be changed later in Grafana UI

  4. Save .env file with your changes.

  5. Start all containers: docker-compose -f docker-compose/grafana-compose.yml -f docker-compose/exporter-remote-compose.yml -f docker-compose/prometheus-compose.yml up -d

    CONTAINER ID   IMAGE                                COMMAND                  CREATED          STATUS         PORTS                                         NAMES

  6. The services are available here:

  7. Navigate to http://localhost:3000 in your web browser and use GRAFANA_USERNAME / GRAFANA_PASSWORD credentials from .env file to access Grafana. It is already configured with prometheus as the default datasource. Navigate to Dashboards → Import dashboard → import ID 17812, select the only existing Prometheus datasource. (The Grafana dashboard was implemented in https://github.com/berezhinskiy/ecoflow_exporter/tree/master/docker-compose)
