iCON-metrics

This is an command line application which reads data from NGBS iCON smart home control systems. The data is processed and is exposed to be scraped from prometheus. Data from prometheus can be display in different ways, but grafana is recommended.

Read data

Data is read from the control system(s). To define the control systems to be scraped, config file needs to be updated.

port: 8080 # port to run on (defaults to 80)
devices:
  - url: http://192.168.1.10 # device address
    sysid: '123123123123' # device ID (printed on the controller)
    password: '123123123123' # password (defaults to sysid if empty)
    delay: 60 # delay in seconds between reads (defaults to 15)
  - url: http://192.168.1.11 # device address
    sysid: '321321321321' # device ID (printed on the controller)

Config.yml validation can be done via the schema. For further configuration options use the schema to explore and validate your config file.

Install on linux

Download the application from GitHub releases and unzip it.

wget https://github.com/csutorasa/icon-metrics/releases/download/1.3.1/icon-metrics-linux-amd64.zip
unzip icon-metrics-linux-amd64.zip

Create systemd service.

touch /etc/systemd/system/icon-metrics.service

[Unit]
Description=iCON metrics publisher

Automatic install script

curl -s https://raw.githubusercontent.com/csutorasa/icon-metrics/master/linux_installer.sh | sudo bash -s amd64

Docker image

Create your config.yml and run the command below

docker run -d -v /path/to/your/config.yml:/app/config.yml -p8080:8080 csutorasa/icon-metrics:latest

If you do not want use 8080 port then use -p${YOUR_PORT}:8080.

Prometheus scraper

Metrics are hosted in prometheus format. The http server port can be configured in the config file.

port: 8080

You need to extend the prometheus config (prometheus.yml) to scrape this application.

scrape_configs:
  # Other scrape configs can be here

  - job_name: 'icon-metrics'
    static_configs:
    - targets: ['localhost:8080']

Metrics reporting

Most metrics can be disabled from the configuaration separately for each device in the config file.

Available metrics:

Metric	Scope	Type	Description	Enable configuration flag
uptime	global	gauge	uptime in milliseconds	N/A
icon_controller_connected	per controller	gauge	1 if the controller is ready to be read, 0 otherwise	controllerConnected
icon_http_client_seconds	per controller	summary	icon HTTP request durations in seconds	httpClient
icon_external_temperature	per controller	gauge	external temperature	externalTemperature
icon_water_temperature	per controller	gauge	cooling or heating water temperature	waterTemperature
icon_heating	per controller	gauge	1 if the controller is set to heating mode, 0 otherwise	heating
icon_eco	per controller	gauge	1 if the controller is in economy mode, 0 otherwise	eco
icon_room_connected	per room	gauge	1 if the room is connected to the controller, 0 otherwise	roomConnected
icon_temperature	per room	gauge	room temperature	temperature
icon_relay_on	per room	gauge	1 if the relay is open, 0 otherwise	relay
icon_humidity	per room	gauge	room humidity	humidity
icon_target_temperature	per room	gauge	room target temperature	targetTemperature
icon_dew_temperature	per room	gauge	room dew temperature	dewTemperature

Grafana dashboard

This data is designed to be displayed in a grafana dashboard. Example dashboards for the system, controllers and the rooms are available to be imported.
