[b][i]Running out of Groups on Lighting? Need more Group Addresses? [/i][/b] As you may know C-Bus Toolkit allows you to create new Applications each of which can have up to 255 Group Addresses. But its important to note that some Application Addresses are Reserved... for backwards compatibility however Toolkit allow you to create Applications at almost any Address. Future releases of Toolkit will nag you if you use a reserved application, so get into the habit now of using the right ones. So what can you use safely? Here's a list of what Clipsal currently uses or has planned for Application Addresses: 25 Temperature Broadcast 38 Room Control System (Clipsal 5 Star) [b]48 - 94 Lighting[/b] 95 Dali Gateway Interface Default Application 112 Ventilation (dampers and fans) 113 Irrigation Control 114 Pool, spa, pond and fountain control 136 Heating (Clipsal 5 Star) 202 Trigger Control (Clipsal SceneMaster, IR Output) 203 Enable Control 205 Audio/Visual 206 Error Reporting 208 Security 209 Metering (gas, water, electricity, oil, etc) 223 Clock and Timekeeping 224 Telephony Status & Control 228 Measurement (light, liquid, temperature, etc) 255 C-Bus Network Management and Control As you can see, there's 46 Application Addresses that are designated as "Lighting" between 48 and 94 (inclusive). You can safely use ANY of these addresses without fear that Clipsal will later allocate one of these to some form of specialised role on the Network. Stick to these Addresses. The default lighting application is 56. If you need a few more, start from 57 and work up from there - its simple and easily recognisable. The list above is not complete, we have roughly another 20 that we will reserve shortly for other functions that will be supported by future hardware. Once again, they will NOT be in the range 48-94.
