zway-http-bridge

Z-Way app to publish all 'modify:metrics:level' events of chosen devices to a HTTP-Server using the method POST. Can be used to build bridges to other ecosystems.

App Options in Z-Way

Option	Description
URL to POST to	The URL which wil be called for each event of selected devices. The URL is called with HTTP POST verb.
Devices	List of devices that events will be postet. Non-selected devices will be ignored.

Data Format

The data that will be send is a simple JSON

{
    timestamp: <Timestamp of event>
    level: <Level of device>,
    id: <ID of device>,
    type: <Type of device>,
    name: <Name of device>,
    metrics: <Full object of metrics of device>
}

Bridge Example

Probably most simple bridge example without any security and checks. Puts all incoming events directly into a MongoDB IoT database.

(Example requires Python, PyMongo, Bottle and, of course, a running MongoDB instance.)

from bottle import request, route, run
from datetime import datetime, time
from dateutil import tz
from pymongo import MongoClient

TIME_ZONE = tz.gettz("Europe/Berlin")

@route('/events', method='post')
def postEventToDatabase():
    json = request.json

    if (json is not None):
        if (json["timestamp"] is not None):
            json["timestamp"] = datetime.fromtimestamp(json["timestamp"] / 1000, TIME_ZONE)

        client = MongoClient('localhost', 27017)
        collection = client.zway.events

        collection.update_one({ "deviceId": json["id"], "date": datetime.combine(json["timestamp"].date(), time(tzinfo=TIME_ZONE)) }, { "$push": { "events": json } }, upsert=True )

run(host='localhost', port=1234)
