sense-exporter

Sense-exporter is a Prometheus exporter for Sense Energy Monitor power usage data.

The Sense API that this tool relies on is unofficial and unsupported by Sense. This repo has no affiliation with Sense. This code could stop working at any time.

Exported Variables

Device-specific metrics are tagged with device_id, make, model, monitor, name, type:

• sense_device_watts is the current power consumption of a Sense-detected or -integrated device
• sense_device_active describes whether a Sense-integrated device is currently active (0 or 1)
• sense_device_online describes whether a Sense-integrated device is currently online (0 or 1)

Sense-detected devices are the devices Sense has discovered by analyzing its power usage. Sense-integrated devices are devices Sense has identified through an integration with a service such as Hue. I'm just making these terms up, but that's what appears to be the case.

Monitor-specific devices are tagged with monitor:

• sense_monitor_hz is the current mains frequency measured by the monitor
• sense_monitor_up is 1 while the exporter is able to collect data from a monitor
• sense_monitor_volts is the current voltage measured at each of the monitor's leads (tagged with channel)
• sense_monitor_watts is the current total power consumption measured by the monitor (sense_device_watts should sum to this number)
• sense_scrape_time_seconds is how long it took for the exporter to collect these metrics for the monitor

Usage

sense-exporter --sense-config=config.yaml
sense-exporter --sense-email=you@example.com --password=s3cr3t

Configuration is described more fully below.

Configuration

Sense-exporter can be configured with a YAML configuration file, command-line flags, or environment variables. If a config file is used, all other configuration is ignored.

Configuration File

Usage: sense-exporter -sense-config <filename>

The config file is structured like this:

accounts:
- credentials:
    email: you@example.com
    password: secret

Multiple accounts can be configured in this way. The full list of options available under credentials:

• email defines a literal e-mail address
• email-from reads the e-mail address from the given file
• password
• password-from
• mfa-from reads the MFA code from the given file (for accounts that require MFA)
• mfa-command executes the given command and expects an MFA code as its output

Flags

If no config file is provided, the following flags can be used, which operate exactly as the YAML properties described above:

• -sense-email
• -sense-email-from
• -sense-password
• -sense-password-from
• -sense-mfa-from
• -sense-mfa-command

Environment Variables

If no config file is provided, these environment variables will be used for any fields not set by a flag:

• SENSE_EMAIL
• SENSE_EMAIL_FROM
• SENSE_PASSWORD
• SENSE_PASSWORD_FROM
• SENSE_MFA_FROM
• SENSE_MFA_COMMAND
