value of power json is always zero

[do9xe]

When sending the following line of python to the REST-API of tradfri-go in server-mode the value 1 is ignored. It will always default to 0.
requests.put("http://10.42.3.34:8080/api/device/65539/power", data = {"power":1})

tradfri-go/router/router.go

Lines 92 to 94 in a05a6fc

	powerRequest := model.PowerRequest{}
	err := json.Unmarshal(body, &powerRequest)
	res, err := tradfriClient.PutDevicePower(deviceId, powerRequest.Power)

The value of powerRequest.Power is already 0 in line 94. I tested with several ways of input, like a json conversion before sending the data or converting it to a string. I also discovered that this also applies to the dimmer and the dimming and setState function.

Thank you for posting your issue.

I can successfully turn on/off the Power state of one of my lightbulbs using curl.

> curl -X PUT http://localhost:8080/api/device/65538/power --data '{"power":0}'
{"Msg":"Changed"}

> curl -X PUT http://localhost:8080/api/device/65538/power --data '{"power":1}'
{"Msg":"Changed"}

> curl http://localhost:8080/api/device/65538
{"deviceMetadata":{"id":65538,"name":"Färgglad","vendor":"IKEA of Sweden","type":"TRADFRI bulb E27 CWS opal 600lm"},"dimmer":203,"xcolor":29713,"ycolor":26431,"rgbcolor":"f2eccf","power":true}

In the example above, I'm running tradfri-go in server mode. Can you try running the same curl commands?

I've added some missing error checks + logging when parsing the REST API requests into JSON which possibly could help you pinpoint your issue.

the line:
requests.put("http://10.42.3.34:8080/api/device/65539/power", data = {"power":1})
does not send the expected json you want, it tries to send a python dictionary instead of a json string so the server cannot unmarshal anything and will respond with a 400 status code.

You should try running
requests.put("http://10.42.3.34:8080/api/device/65537/power", data = '{"power": 1}')
instead as this actually sends the string the server is expecting.
