Controlling a light through DM in LUA

[Rob H]

To cut down on all the editing required, it's probably a good idea to put all the buttons in a frame with the name of the path to the device, then use relative naming on the buttons. e.g. suppose the device was Fordrat8\ElkM1EZ8\Light 14 - you would use that as the name of the frame. Then a button in that frame would be called <^>. In fact, anywhere the name of the button is used you would substitute <^>, including in state rules and Lua code.

If used in a Lua string then use [[ ]] notation to delimit the string.

Yep forgot that trick. Here is an updated example using the relative naming. Now just rename the frame and your all set to go. Thanks Rob

Again all you need to do to reskin this is to change the graphics to yours and rename the frame to one of your device paths. In fact once you have the graphics reskinnned you can copy and past the frames as many times as you like and just rename the frames to get all your light controls quickly.

I am a little confused here. I understand how to get this to work, but why can't we put the 'actions' where they belong, in the button's Actions tab (without having to write extra code ourselves)? It just makes more sense IMO.

Even though I can now control my lights through Lua, I have yet to be able to figure out how to use this in a way that will give me the percentage of the light:

local device = DeviceManager:GetDeviceUsingLocationName ('Den\\Sconces')
device:GetControlValue ('Level')

Can someone please clarify how I could take the returned value and use it in another line of script? I've tried printing the table (device), but it generates a huge list of variables that includes what I assume to be everything from the device manager.

Thanks in advance.

Try this

local device = DeviceManager:GetDeviceUsingLocationName ('Den\\Sconces')
local level = device:GetControlValue ('Level')

Bingo! Thanks, Rick.
