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]

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_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

web.listen-address	Address to listen on	:9452

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.
