Tuya exporter for prometheus

Prometheus exporter for Tuya-based smart plug devices. Tested with Immax Neo Lite smart plug.

Setup

• Obtain device ID and key, here is excellent guide by @codetheweb
• Populate config file, here is an example:

- name: plug-kitchen-1
  id: 87e98a987b87b12354a54c
  key: 0987654321abcdef
  ip: 192.168.1.5

Run locally

./exporter
ts=2024-02-25T08:18:50.577Z caller=main.go:83 level=info msg="Starting tuya_smartplug_exporter" version="(version=v1.0.0, branch=main, revision=9d0b7b3)" config=config.yaml
ts=2024-02-25T08:18:50.582Z caller=main.go:98 level=info msg="Configured 1 devices"

ts=2024-02-25T08:18:50.583Z caller=tls_config.go:316 level=info msg="TLS is disabled." http2=false address=[::]:9999

Run using docker

docker run -ti -v $(pwd)/config.yaml:/config.yaml:ro ghcr.io/rkosegi/tuya-smartplug-exporter:v1.0.1
