tag group write, only different data - gjniewenhuijse - 05.12.2016
Hello,
I have a script that writes values to a group addresses:
AllStatus = grp.tag('test')
AllStatus:write( true )
I want to write only to that addresses that have different data then the value to write. In this case only write value true to addresses with tag 'test' and value false.
RE: tag group write, only different data - admin - 05.12.2016
Code:
function tagcheckwrite(tag, value)
local objects = grp.tag(tag)
for _, object in ipairs(objects) do
if object.data ~= value then
object:write(value)
end
end
end
tagcheckwrite('test', false)RE: tag group write, only different data - mlaudren - 05.12.2016
if you look for the object AllStatus, you'll find it's an array with all object.
You can do a loop on this array and write the value only if it's not the same
Will look something like:
for _, item in ipairs(AllStatus) do
if item.value != newvalue then
grp.write(item.address, newvalue
end
end
Edit: Admin send a reply just before my. take his
