Hi! I try send notifications to LaMetric Time (I know about binding, but it did not provide icons in notifications)
Here is curl command:

curl -X POST -u "dev:xxxx" -H "Content-Type: application/json" -d " { \"model\": { \"frames\": [ { \"icon\":\"a2867\", \"text\":\"Hello\"} ] } }" http://192.168.1.80:8080/api/v2/device/notifications

I try and no luck:

executeCommandLine(Duration.ofSeconds(6), "/bin/sh", "-c", "'curl -X POST -u \"dev:xxxx\" -H \"Content-Type:application/json\" -d \"{\"model\":{\"frames\":[{\"icon\":\"a2867\",\"text\":\"Hello\"}]}}\" http://192.168.1.80:8080/api/v2/device/notifications'")

executeCommandLine(Duration.ofSeconds(6), ("curl -X POST -u 'dev:xxxxx' -H 'Content-Type:application/json' -d '{\"model\":{\"frames\":[{\"icon\":\"a2867\",\"text\":\"Hello\"}]}}' http://192.168.1.80:8080/api/v2/device/notifications").split(" "))

Read DOCs, and not found how to send -u parameter from curl in openHAB sendHttpPostRequest HTTP Actions

Why don‘t use sendHttpPostRequest?

I just checked my code and I don‘t use -u at all

3

Need to provide user and pass in request

-u "dev:xxxx"

I dont know how

sendHttpPostRequest(String url, String contentType, String content, Map<String, String> headers, int timeout)

Where to put -u?

You can try the code below - just change your ApiKey, ip-address and the json-data:

val String LaMetric_ApiKey = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
val String LaMetric_Notification_Endpoint = "http://dev:" + LaMetric_ApiKey + "@192.168.100.50:8080/api/v2/device/notifications"
val String LaMetric_Notification_Headers = "application/json"
var String LaMetric_Data = "{your json here}"
var String API_RETURN = sendHttpPostRequest(LaMetric_Notification_Endpoint,LaMetric_Notification_Headers,LaMetric_Data,20000)
5

Yes! Thank you @Flip :grinning:

Is it working?

7

Yes

Well done :slight_smile: Maybe you can mark the code above as solution - just in case somebody else is having this problem

Did it already :slightly_smiling_face:

I’m struggling using this “My Data (DIY)” App for the Lametric Time with OpenHAB 3.
Link to the documentation: My Data (DIY) App on LaMetric Market | LaMetric Time clock for smart home

I’m lost what " 1. Expose your data to some URL available in the same local network with the device in predefined JSON format (more about that below)." actually means.
How to achieve this? Do i need to use the HTTP binding for that?
What URL do i have to use? Help is really appreciated!

You need to create file /etc/openhab/html/lametric.json, adjust path according to File Locations.
Here is my rule:

I really appreciate writing a possible solution to my problem!
But sadly i didn’t get any point of the solution. :frowning:

What about the HTTP binding and the configuration of the thing? Do i need a Channel in this Thing?
How to fill the field of the “Basis-URL”?

I was expecting that i have to do something in the area of this:

rule "Update My Data DIY"
when
        Item PostHTTP received command ON
then
        val String URL = "http://192.168.178.91/jsonmydata"
        var String contenttype = "application/json"
        var String jsondata = '{"frames" : [ {"icon": "794","text": "Hello!"}]}'

        logInfo("Update My Data DIY", "Sending Command" + jsondata + "data end")

        sendHttpPostRequest(URL, contenttype, jsondata)
end
