Power of BACnet Web Services Released

TRY YOURSELF

From your browser
Try BACnet/WS in our lab. in South England
Follow the steps below

  1. To open a secure access to the site run this key-link.
    https://www.openport.io/l/4302/jJ6a0drhXKX7EbMH
    This will hold the link open from your computer for 24 hours.
     

  2. Browse the network  (who-is):
    http://www.openport.io:4302/bacnetws/.bacnet/.local?metadata=cat-all
    This will give you a result set of 4 devices of which 3 are virtual BACnet devices representing LoRaWAN sensors.

  3. Now you can easily dig down by copying items from the result set and appending to the URL.
    For example, let us investigate the CO2 sensor, device 1820:
    http://www.openport.io:4302/bacnetws/.bacnet/.local/1820?metadata=cat-all
    You will get a result set with all the BACnet objects in the device.
     

  4. Again let us dig deeper into the CO2 sensors Analog Input object, by copy paste from the result set.
    http://www.openport.io:4302/bacnetws/.bacnet/.local/1820/analog-input,5?metadata=cat-all
    The result set will show you all the properties within the CO2 Analog Input object.
     

  5. Then let us get the Present Value only, and this time in JSON format.
    http://www.openport.io:4302/bacnetws/.bacnet/.local/1820/analog-input,5/present-value?metadata=cat-all&alt=json
    Try also using parameter "&alt=plain"
     

  6. Finally let us check one trend-log object in the DINGO-device (device 5777) that trend-logs the CO2 values.
    Let us request data from 07:00AM to 11:00AM (example is 3d Sept. 2021,  change date to yesterday or today)
    http://www.openport.io:4302/bacnetws/.bacnet/.local/5777/trend-log,83/log-buffer?published-ge=2021-09-03T07:00:00&published-le=2021-09-03T11:00:00&reverse=0
    Notice how the CO2 value rise after 8:00 AM when people enter. Maybe they should open a window 😁

You can of course also subscribe to COVs (Change of Values) via web-socket or http-endpoint (or https-endpoint).
All about that here.
You can also test it out via the test client:

http://www.openport.io:4302/testclient.htm

The other way around setting values via BACnet/WS also possible.
All about that here.
 

You can apply full security via https and OAuth 2.0

Then finally you can check out our easy to generate reports, where you can specify user-interface as you want.
In this case the user-interface is just a simple table (html-report=1).
