I don’t have a Home processor, but for sure, you won’t be able to load an Xsig symbol using the setup program on an iPad or anything like that. To get this working with Crestron Home, you would probably need another Crestron processor that you would have the Xsig on that HA communicates with, and then your Crestron Home processor would send commands to that via EISC or whatever method CH uses.
Perhaps another programmer with Crestron Home can comment on how you talk to another processor to control stuff, but I have only programmed with SIMPL and S+. As far as I know, Home doesn’t even have a debugger built-in, and it’s still elementary. You can use plenty of older equipment with it, but you’re pretty limited with other things you can easily do in SIMPL.
Depending on what level of Crestron programming you’ve take this page has plenty of info and will lead you down the rabbit hole, so to say. https://sdkcon78221.crestron.com
