How do Repeat Buttons work?

Hi

I guess I’m missing something, but I cannot get repeating buttons to work. Basically I need to execute a script every second to get the status from my projector as I can only get it via the TCPClient and show it in a label.

I have currently a normal button which I press and there is a “clicked” event listener which then fires the script. I thought I could just change the button type to “Repeat” and set the repeat interval to 1000 miliseconds, but nothing is happening. Already tried all other Events, but none of them triggers my script function onChangeRequest().

Anything that I’m missing here?

Thanks

You should send request for new status in onPoll. If you don’t wish to constantly poll, use the HasSubscribers function to check if your attribute has any active watchers.

Plugin "HasSubscribers" Function

In the 3.9.0 release a new HasSubscribers function was added to the Device object allowing you to check if it is actively being used on the current page. This means that any Plugins polling HTTP REST APIs can perform conditional checks to see if it needs to send requests. The function accepts an optional Attribute argument in case there is a specific attribute you are targeting. By not providing an argument, it’ll check to see if any attributes are referenced. Attached is a simple example. Tog…

Thanks a lot. That explains it. onPoll is the perfect solution.
