How would you be displaying values from 100+ things? In a grid, list or other widget(s)?
Is this version 7.2 where you are trying to us the property update push functions to see the data?
OR what service are you using to get the properties? I assume it would be a custom service?
If it is in a dashboard you should only need to configure the mapping for a single thing on a gadget which would represent each thing? (Though with this volume of UI it will run slowly).
1. We created custom widget for display properties of 100+ things.
2. Yes Thingworx 7.2.
3. We have mapped getProperties serviceinvokecompleted event to a service which retrieves based ThingName Property in the Generic thing. This generic thing ThingName property is updated by all other 100+ things on data property change with Thing name which got update.
4. It is not Thingworx Dashboard or we are not using any thingworx widget, we have created our own custom widget to solve UX issues in thingworx.
