Yes, it probably would. One thing you can try is adjusting the UI performance setting on the system settings page. Try setting it to low. This will affect everything though (watchlist and views), not just the charts.
Thanks for the inquiry regarding OPC development work.
This is currently something that's on our development plan, and we have dome some background work on it.
At this point however, we would welcome a community member or end user client to partially sponsor this kind of development work in order to see it through to release.
If this is something that you might be interested in, please contact us directly, and we can exchange some information and details about this project.
Thanks for posting your inquiry.
This is something that Mango could definitely be updated to support, and we can slot it into our development list for future updates.
If adding this capability is part of a project you're working on, please contact us directly if you may require this development to be accelerated by contributing to a sponsored piece of development.
To answer your initial question, yes, this functionality can be added to Mango. Depending on your exact needs, there are a few of ways this can be done: 1) extend the HTTP publisher or create a new publisher, 2) use a data source that can act as a peer in a network (like BACnet), or 3) create specific functionality for inter-Mango communication.
As i say, the correct solution depends on what specifically you need to do. Quotes and time lines can be provided once the details have been worked through.
Another possibility could perhaps be to use the http publisher with some voip account or SMS gateway provider. The Betamax voip family (voipbuster etc.) have an http api with which you can send your SMS message using GET variables. Usually the SMS rates are better (at least in Europe) than with a normal GSM subscription.
This was in fact considered, but was evaluated to have a complexity level that can only be described as hideous. As i recall, conceptually, it appears hierarchical, but in the browser it would need to be flattened into HTML. This makes for a lot of problems in the view editing pages.
So, yes, it can probably be done, but it would be ugly.
Thanks for the idea. Your solution for 1-wire sounds intresting. I think i will use similar method. I have also USB dongle. An other problem is that I have thermocouples connected which are not supported with Mango.
That would depend more on the mapping API than on Mango. Mango doesn't have any explicit fields for storing a point's geolocation information, so i'm not sure where you would be pulling that from. But, that's what something like Google maps would need.
The configuration is exported to JSON. See http://www.json.org/. I realize this format is not nearly as widespread as XML, but it provides a much clearer mapping to lists, objects, and maps. In the future we offer to export to XML as an option, but we'll wait to hear what people thing of how it is first.
To own the rights to it you need to buy an extended commercial license (the one with the source code). Then, anyone can build the driver, not just Serotonin.
If you don't need to own it you would effectively commission its development for inclusion in the commercial version. (Several other features of Mango were built this way.) Something like this would cost around $1 - 1.5 K CAD.
