Help to newbie

Hi,

 

I'm new to Lua and HC3 Quickapp programming. I know i have a long way to go and maybe I've started on the wrong foot, or with a project to big. I'm not new to programming. That said i think Fibaros QA documentation is really bad, and a big mountain to climb. I've read @jgabs tutorial on QA programming, and that have helped in sove way, but it still seems that you need to have a lot basic knowledge to understand everything he is writing. You almost have to have inssider knowledge.

 

However i have a problem with the QA im looking at/learning programming at. I'm not able to update a variable in a child device. No matter what i does i cant update the variable. 

 

My QA is an app that can disable a relay after a certain time. All my relays are supposed to be created as a child when the parent is called whith that relay no. Then the relay is turned on and the disable time needs to be written to a variable in the child, but im not able to do that.. When the disable timer is reached the relay turns off.

 

The childs will not be deleted, but the next time a specific button is pressed, the relay turns on and the disable timer variable should be updated again.When the disable timer is reached the relay turns off, and so it continues

 

I've tried the following, but nothing is working

 

                    child=self.childDevices[ChildID]

                    child:setVariable("Time", "test")

                    local name = "Test"

                    local value = "test"

                    fibaro.call(ChildID,"setVariable",name,value)

                    self:debug("RelayID",child:getVariable("Relay_id"))

 

I can read the variable without any issues.

 

Please advise what to do, and maybe some literature on how to learn Fibaro HC3 LUA, especially the parameters for the different commands

It looks like it should work...

This prints nothing?

Hi jgab

 

Strange. That seems to work. Don't know why, as i don't see any difference compaired to my code. Apparently it just needed a little @jgab dust of magic. Thank you for your help. I'll keep on learning. For now i added the variable part to the child class, and then call that routine when the button is pressed
