Govee api command in a rule

[Constantinos_Contis]

i have a Govee H6199 tv backlight strip and trying to incorporate into my openhab just to turn on and off,I have found this Govee api ,i got an api key allright and i guess i have to use this example

Request URL: https://developer-api.govee.com/v1/devices/control
Request Method: PUT
Request Header:
Content-Type : application/json
Govee-API-Key : 00000000-729c-4b82-b536-000000000
Request body
{
"device": "34:20:03:15:82:ae",
"model": "H6089",
"cmd": {
"name": "turn",
"value": "on"
}
}

in a rule to turn on my strip…any ideas?

If you want to send some HTTP, you would normally use the HTTP binding. Or HTTP Actions in a rule. Details vary by openHAB version in use.

[Constantinos_Contis]

i sure know that,i just dont know what syntax to use for the rule.I use http in rules like

rule "httpexample"
when
Item test received command
then
 sendHttpGetRequest("https://url to send to make something work")
end

i just dont know how to transform the Govee api example to one line url to use with “sendHttpGetRequest” if possible…

i just dont know how to transform the Govee api example to one line url

You can’t, its a PUT and needs a message body (which you can build in a rule).

Repeating the hint, details vary by openHAB version in use.

[Constantinos_Contis]

i am using openhabian 2.5.12…

Here are the docs

An example with JSON

HowTo: Use Philips Hue sensors (Motion Sensor / Dimmer Switch)

Yes, I do. You can send a command in a rule or use a Switch item for it. demo.items Switch hueMotionSensorStatus demo.rules rule "Switch Hue Motion Sensor ON / OFF" when Item hueMotionSensorStatus changed then val url = "http://<bridge ip address>/api/<username>/sensors/<id>/config" var String body = "" if( hueMotionSensorStatus.state != ON ) { body = '{"on":false}' } else { body = '{"on":true}' } logInfo("demo", "Send command '{}' to {}", body, ur…

I think you’ll need toput your API key in headers
Example using headers here -

[OH3 / Javascript] Trying to create a http PUT request, but failing?

Actually my working rule looks like this: var Exec = Java.type("org.openhab.core.model.script.actions.Exec"); var HTTP=Java.type("org.openhab.core.model.script.actions.HTTP"); var openHAB_PID =Exec.executeCommandLine(parseDuration("1s"), "pgrep", "-f", "openhab.*java"); logger.info("openHAB_PID = {}", openHAB_PID); var headers = []; headers["Authorization"] = "Bearer MyAPIToken"; headers["WWW-Authenticate"] = "Basic"; systemstatus_thing=HTTP.sendHttpGetRequest("http://127.0.0.1:8080/rest/thi…

[Constantinos_Contis]

i came up with this rule based on my limited knowledge

rule "govee"
when
    Item test changed
then
    val url = "https://developer-api.govee.com/v1/devices/control"
	var String header = "Govee-API-Key:  0af6b18b-0303-4c87-b68a-17xxxxxxxxx"
    var String body = '{"device": "34:20:03:B6:xx:xx", "model": "H6199", "cmd": {"name": "turn","value": "on"}}'
    sendHttpPutRequest(url, header, "application/json", body)
end

but i get an error

2021-06-18 10:14:21.152 [ERROR] [ntime.internal.engine.RuleEngineImpl] - Rule 'govee': An error occurred during the script execution: Could not invoke method: org.eclipse.smarthome.model.script.actions.HTTP.sendHttpPutRequest(java.lang.String,java.lang.String,java.lang.String,int) on instance: null

@Constantinos_Contis

i get an error

For some reason, you’ve decided to give your parameters in a different order from the document, so it’s probably struggling to work what is which.
sendHttpPutRequest(url, contentType, content, headers, timeout)

Headers is special, headers is a Map type object, like a list or array, because it usually has multiple elements.
That’s why the example I showed you uses

When you are experimenting with this, it’s useful to get any response message. You need to give a timeout to collect that.

val putresponse = sendHttpPutRequest(url, contentType, body, headers, 10000)
logInfo("test", "PUT response: " + putresponse)

[Constantinos_Contis]

thnx…one question, is it possible (and easier) to make a script with the document example and run it with

executeCommandLine("/etc/openhab2/scripts/govee.sh")

in my rule?

[rossko57]

Sure. Don’t see why that would be any easier than a five-line rule, but just find out how to make HTTP requests in whatever scripting language you want to use. Remember you want to pass an on/off selection somehow.

[Constantinos_Contis]

thank you,i dont have the slightest idea about http requests …and http in general i am trying to learn from docs and examples…

[rossko57]

Okay, so probably best for now to stick with the docs and examples that you have. What does your rule look like now, is it working?

[Constantinos_Contis]

i am trying to do some work and to deal with a 4 yo so later tonight i will give it a try…

[rossko57]

I realise now I gave a poor example of ‘headers’ scripting - that was in javascript, not the DSL language you’re currently using.
Looking for a DSL example led me to this …

sendHttpGetRequest: Error in Documentation?

Hi all, I’m trying to get rid of HTTP Binding by implementing a DSL Rule which periodically sends a GET-Request. Since the request needs some headers to get the data in json I’m trying to use sendHttpGetRequest(String url, Map<String, String> headers, int timeout) as described in https://www.openhab.org/docs/configuration/actions.html#http-actions. Unfortunately this gives me the following error: 2020-03-06 09:47:00.536 [ERROR] [ntime.internal.engine.RuleEngineImpl] - Error during the execut…

The upshot seems to be that headers are not supported in OH2 actions, and mention of them snuck into OH2 docs in error.

I don’t think this is going to work this way. You may be forced to use an external script after all (probably a bash script using curl).

[Constantinos_Contis]

got it thnx
i made this script named it govee.sh and put it in openHAB-conf\scripts folder

#!/bin/bash
curl 'https://developer-api.govee.com/v1/devices/control'--header'Govee-API-Key:0af6b18b-0303-4c87-b68a-xxxxxxxxxx'--header'Content-Type:application/json'--data-raw'{"device":"34:20:03:B6:xx:xx","model":"H6199","cmd":{"name":"turn","value":"on"}}

and test it with a rule

rule "govee"
when
	Item test received command
then
    executeCommandLine("/etc/openhab2/scripts/govee.sh")
end

and i get in the log

021-06-18 15:09:47.866 [INFO ] [lipse.smarthome.io.net.exec.ExecUtil] - executed commandLine '/etc/openhab2/scripts/govee.sh'

but nothing really happens.

@Constantinos_Contis

executeCommandLine("/etc/openhab2/scripts/govee.sh")

use the extended syntax
var RET = executeCommandLine("/etc/openhab2/scripts/govee.sh", 2000)
to get output returned. You may have to redirect the output from your curl command.
Alternatively you can redirect the output of the curl command to a temp. file within your shell script.

[Constantinos_Contis]

got it working thnx,my script is

#!/bin/bash
curl --location --request PUT 'https://developer-api.govee.com/v1/devices/control' --header 'Govee-API-Key: 0af6b18b-0303-4c87-b68a-xxxxxxxxx' --header 'Content-Type: application/json' --data-raw '{"device": "FF:AA:A4:C1:xx:xx:xx:xx","model": "H6199","cmd": {"name": "turn", "value": "off"}}'

no need for extended syntax.

[skylineguy (Sven)]

Thanks for sharing your solution. I also want to switch on and off a Govee H6199 with openhab. Also using openhabian 2.5.12.

Tried your way, but always get an error when running the script (of course I replaced Govee-API-Key and MAC-Adress):

{“message”:“service is busy please try again later”,“status”:500}

Any idea anyone?
Thx for helping.

[treybert (Trey)]

You might be doing to same thing I did. For device name, even though it says its the mac address, its not. Do a GET on https://developer-api.govee.com/v1/devices with your api key header to find the actual address
