myStrom prometheus exporter

Export myStrom WiFi Switch report statistics to Prometheus.

Metrics are retrieved using the switch REST api. This has only be testet using a WiFi switch with firmware 3.82.60, but should be backwards compatible with all 3.x firmwares.

To run it:

$ go build
$ ./mystrom-exporter [flags]

Exported Metrics

Metric	Description
mystrom_up	Was the last REST api call to the switch successful
mystrom_report_watt_per_sec	The average of energy consumed per second from last call this request
mystrom_report_temperatur	The currently measured temperature by the switch. (Might initially be wrong, but will automatically correct itself over the span of a few hours)
mystrom_report_relay	The current state of the relay (wether or not the relay is currently turned on)
mystrom_report_power	The current power consumed by devices attached to the switch

Flags

$ ./mystrom-exporter --help

switch.ip-address	IP address of the switch you try to monitor	``
web.listen-address	Address to listen on	:9452
web.metrics-path	Path under which to expose metrics	/metrics

Supported architectures

Using the make file, you can easily build for the following architectures, those can also be considered the tested ones:

OS	Arch
Linux	amd64
Linux	arm64
Linux	arm
Mac	amd64

Since go is cross compatible with windows, and mac arm as well, you should be able to build the binary for those as well, but they aren't tested.
The docker image is only built & tested for amd64.

Packages

Packages are built automatically on release, and container images on push to the main branch.
