UI Manager Issues

1

Hi all!

I trust that you are doing well. I am experiencing some issues with the Manager UI in openremote.

The core idea is that I have a TCP server running, getting data from a BLE mesh network. For this, I am using the TCP agent (I was using a websocket, but when I send messages downstream to my Websocket Server I keep getting a 1006 disconnect error. Not sure why this is happening, but this is a different issue).

I then have a things asset (Street Light), which has a few custom attributes. This asset is connected to my TCP agent. Upon receiving a packet (in JSON format), I filter the data I need to update an attribute via “Value Filters”. If I want to send data down to my TCP server, I use a “Write Value” item.

The issue being that as I am receiving data and the attributes are updated, the UI almost become irresponsive. So, I cannot update attributes, I cannot save the asset etc. I am not sure exactly why this is happening.

I am receiving data every 5 seconds. Everything is also a local setup and I am hosting from a PC. I am busy evaluating Openremote for large BLE mesh networks to see if we can move away from our current cloud solution.

I have automated most of my commissioning already, by using the Openremote API.

Here is my TCP agent:

Here is an example of one attribute:

I absolutely love the platform, currently, my concerns are:

  1. How would openremote handle say 500 things assets, with 15 attributes each, updating say every 10 minutes
  2. Currently, with a single asset I cannot do anything when an asset attributes updates…
  3. Is using value filters for such large systems a good idea? So everything comes through a single TCP agent and all my assets are linked to this agent. Would Groovy rules be more appropriate?
  4. Also, using value filters, if I receive 5 updates via my TCP server, only some shows on the UI, and they alternate, but I am assuming this is just the way the value filters work, here is an example:

Hi, could anyone help with this please?

Hi! Let me try and help you out here.

  1. As OpenRemote we have various installations with similar numbers of assets and “attribute events” (as we like to call them). It should be able too handle these updates, depending on the amount of rules, custom logic, and system specifications of course.

  2. Yeah, this is an issue we’re aware of, and it is really annoying haha.
    I’ll make sure we open a GitHub issue on it, so we can discuss it internally for review.

  3. I should ask @Rich on this, but I think using value filters (or any processing using meta items) is more performant than using our Rules engine. It might be different at larger numbers, but don’t quote me on that.

  4. I’m not sure what you’re referring to here. If you have a reproducible example, please share.
