I've purchased a couple of used prontos to add some more remotes to the system.
Is there any clever way to share system globals between several remotes. My first thought would be connecting to an SQL database, but I don't see that happen with prontoscript.
Another thought is some sort of program on my server, which I can configure, so that it writes into .XML, which again could be parsed from several prontos. I think this could work (although redesigning the entire config would be necessary), but what sort of program does this?

You could write your own web application (some have talked about PHP) that does this in the Web (http) container. However, you are in a situation where you must "roll your own".

If you just need global on/off (boolean) status for 4 or fewer variables, you could always wire your relays on an RFX9600 to the power input and then update the state of your system via setting relays.

However, I suspect you are looking for a more robust solution and this will indeed involve standing up a server and putting some custom-written software on it.

thats the answer I was afraid someone would give. Using RFX relays is not an option - power on/off is done either through IP or RS-232, that's not the problem. I was thinking more in the terms of a status page, where I can see which equiptment in on, inputs, tv-channel and so on for each zone. And maybe if I press "bedroom" in the living room, the remote will show exactly the same as the one in the living room.
I just hoped that a piece of software already existed

I as well have often thought it would be great to be able to store System Globals in a central place for use with multiple remotes. That being said, my configuration file does contain a System Status page. While the System Status page is local to the particular remote of course I do find it useful from time to time.



My System Status page shown above can be accessed from any page throughout my configuration file via an invisible button up in the top right corner covering the time, date, wi-fi, and battery level system items. A normal button press will take you to my Lighting page. An extended button press will take you to the System Status page. The System Status page reports the currently selected activity, the last BD/DVD changer in use, and the power states for key components. Tapping a given value will allow you to update that value on the fly if needed in order to get the remote back in sync with the given component or function. Settings options for the scroll wheel while under my DVD Juke activity are included as well.

For anyone interested, my current configuration file is available for download here. A PackAndGo version of my configuration file is available as well which can easily be run in PEP v2's Simulator rather than downloading it to an actual TSU9600.

For this need, a place to store house wide globals, "standing up a system server" as Lyndel suggest is as simple as having a small PC somewhere that is on 24/7. Such a PC can cost less than $500 and may be had in a little "Cube" format similar to Asrock machines. If done right no Keyboard, mouse or monitor is needed. Handy to have, but not needed. All you really need is a LAN connectiion and something like MS Remote Desktop.

If there is a demand I will take the program I use (Pronto PAL) strip it down and set it up for others to use. It is table driven and uses some identifier for the device. IP address is easiest if you can use a static IP or a permanent DHCP reservation. The PAL handles anything that will talk to it over TCP/IP, nothing fancy, very little overhead, very fast.

Drop me an email if interested and based upon interest I might invest a few hours to do it. It will be for Windows and should only take me a short amount of time.
