kasa_exporter

Prometheus exporter for TP-Link Kasa smart home products.

The metrics are exported for all devices find on a local network.

Supported products

There might be others that have the same API. The following ones have been tested.

Smart wifi plug (HS110)

Smart wifi plug (KP115)

Exported metrics

All three as reported by API with device_id and device_alias labels:

• device_electric_current_amperes
• device_electric_potential_volts
• device_electric_power_watts
• device_electric_energy_joules_total

Building

Install Rust, then from cloned repo:

$ cargo build --release

Usage

After Building, run the command to get help:

$ ./target/release/kasa_exporter --help
Prometheus exporter for TP-Link kasa devices

Usage: kasa_exporter [OPTIONS]

Options:
      --web.listen-address <LISTEN_ADDRESS>
          Address on which to expose metrics and web interface [default: [::1]:12345]
  -h, --help
          Print help
  -V, --version
          Print version

Note that web.listen-address expects <ip>:<port>, e.g.:

• 127.0.0.1:12345 for IPv4
• [::1]:12345 for IPv6

Example response:

$ curl http://localhost:12345/
