sense

This package is an incomplete implementation of an entirely UNOFFICIAL and UNSUPPORTED API to access data for a Sense Energy Monitor account. This repository has no affiliation with Sense.

Because this is unsupported, this package may stop working at any time.

The API in this package is not stable and I may change it at any time.

Usage

import (
	"github.com/dnesting/sense"
	"github.com/dnesting/sense/realtime"
)

func main() {
	ctx := context.Background()
	client, err := sense.Connect(ctx, sense.PasswordCredentials{
		Email:    "you@example.com",
		Password: "secret",
	})
	if err != nil {
		log.Fatal(err)
	}

	fmt.Println("Monitors configured under account", client.AccountID)
	for _, m := range client.Monitors {
		fmt.Println("-", m.ID)

        // Use the realtime Stream API to grab one data point.
		fn := func(_ context.Context, msg realtime.Message) error {
			if rt, ok := msg.(*realtime.RealtimeUpdate); ok {
				fmt.Println("  current power consumption", rt.W, "W")
				return realtime.Stop
			}
			return nil
		}
		if err := client.Stream(ctx, m.ID, fn); err != nil {
			log.Fatal(err)
		}
	}
}

MFA

If your account requires multi-factor authentication, you can accommodate that like:

mfaFunc := func() (string, error) {
    // obtain your MFA code somehow, we'll just use a fixed value to demonstrate
    return "12345", nil
}
client, err := sense.Connect(ctx, sense.PasswordCredentials{
    Email: "you@example.com",
    Password: "secret",
    MfaFn: mfaFunc,
})

Your mfaFunc will be called when needed.

Notes

This implementation is incomplete, and what's there is incompletely tested. If you wish to contribute, here's how the project is laid out:

|-- internal
|   |-- client         contains an (incomplete) OpenAPI spec and
|   |                  auto-generated code that does the heavy lifting
|   |-- ratelimited    implements some HTTP rate limiting
|   `-- senseutil      helper functions, mocks for testing, etc.
|-- realtime           contains a complete-ish AsyncAPI spec but
|                      hand-generated code implementing the real-time
|                      WebSockets API
|-- senseauth          implements the Sense artisinal OAuth
`-- sensecli           helpers that CLI tools might find useful

Debugging

If you need the gory internals to figure something out:

httpClient := sense.SetDebug(log.Default(), nil)
client, err := sense.Connect(ctx, credentials, sense.WithHTTPClient(httpClient))
