So upgraded to PRO and all I can say is WTF I thought there would be a module(memory) or something to plug in as an add-on but to just unlock existing functions in my ISY that were already there? What kind of money grab is that? If there is no difference between the regular and a pro besides UD allowing you full access to their device why not just have them all the same. Dont get me wrong the ISY is a good device but this just seems shady from a company.And yes upgrading fixed the issue because it is not a device limit(I wasnt even close) it is a device, scene, folder,program limit. How about in the info tab in the designer you show us where we are at so we dont waste DAYS trying to add a single device only to have it continually fail with NO mention of the fact I have reached a imaginary limit and need to give up more money to be allowed to add more devices!
