Create custom event

[Neo Andersson 230]

Hello guys

 

Maybe this is an absolute stupid question, but i will give it a try

 

Is there any possibility in LUA, to create my own event, that will fire, when a certain variable's value has changed ? Like ex i have a variable AGE, and its initial value is 10. Whenever, wherever this AGE variable got a new value, i would like to trigger an event, so I can do some action upon that event.

 

Is this too much that I want?

 

Big thanks for any help

Is the variable a Lua variable or a fibaro global. Fibaro globals already emit events when they change value.

You can create custom events and fire them

It is a LUA variable, not fibaro global

 

Maybe I explained mayself incorreclty...my goal is, to automatically get that event to be fired..

like when a device state is changed we can listen to that in a function, and do some stuff..

You can always fire a customEvent when your change the value of the variable - however, it's difficult to add the value to the customEvent in a safe way. One unsafe way is to encode the value in the events userDescription.

Probably its my fault..I didnt explain correclty what is my goal.

I dont want to fire the event myself..

I want to fire that event by Fibaro, whenever the value changes.

Like we have with devices

The function above allowes me to do an action when device with ID 88 changes its value

Something similar can be done?

 

 

I have more thousends of code in one of my QA. In many many places, when AGE variable gets a new value, I need to update some UI element. So every time I need to write self:updateVeiw("lbl","text",age)

If there was the possibility, to listen for thet value change, then I could call only once the updateView function, and not write it like 500 times

Maybe my aproach is totally incorrect, sorry for that

Ok, instead of doing 

AGE=x

in 500 places, you could do

and then

500 times.

 

If AGE is a global variable you could do

The advantage is that you don't need to change the code - use AGE=x. You can also check several variables with the same loop and have separate handlers for them. Disadvantage is that if AGE changes values quickly it won't show, however, you will have the latest 1s value which is probably not a problem for the UI.

Could make it every 2000ms if it's not a realtime value.
