Illusion Posted April 24, 2012 Posted April 24, 2012 The tendrils of this have been discussed in other topics, but I thought it would be nice to have all the hard limits in one place. Also I do not know what all these values are so chime in if you know something. ISY Maximums: Pro: Max. Devices/Scenes 1024 Max. Programs 1000 Base: Max. Devices/Scenes 256 Max. Programs 300 PLM Maximums: V 63 and below 417 links maximum above v 63 2000 links but the processor was only able to handle about 800 really reliably Dual Band PLM 1023 links with a processor that can handle all that. Questions: The real limit on scenes is 255 right? So what does Max. Devices/Scenes mean? Is the program limit a hard number, or is it an available memory issue? and therefore an estimate?
Brian H Posted April 24, 2012 Posted April 24, 2012 The ISY Maximums you listed are for the Pro versions of the 99i and 994i The Standard 99i and 994i maximums are 256 Devices/Scenes and 300 Programs.
jdale Posted April 24, 2012 Posted April 24, 2012 In terms of links in the PLM database you need a link for each device to be controlled, and for each device to inform the PLM about its status. E.g. for a SwitchLinc you will typically need 2 links. Additionally, if a device appears in multiple scenes, it will need a link for each scene. So for a SwitchLinc that appears in 2 scenes, you actually need 3 links. One to tell the PLM if you press the paddle on the SwitchLinc, and two to control it. So these add up faster than you might expect.
sanders2222 Posted April 24, 2012 Posted April 24, 2012 Is there a way to poll the ISY to find out how many devices and programs you have?
Michel Kohanim Posted April 25, 2012 Posted April 25, 2012 Hi sanders2222, There's no "summary" call that would provide you with that information. This said: /rest/nodes gives you a list of devices and scenes in XML /rest/programs gives you a list of programs in XML With kind regards, Michel
