Too long delay for Dashboard refresh

[FabioPaolini]

Hi. I am try to use Domoticz for a simple application.
I have 2 virtual Push On Button. One is used to open a relay and the other is used to close the same relay. So my Dashboard has 3 componets:

1) The open relay button.
2) The close relay button
3) A component just to monitor the relay status.

If I press the "open relay button" it remains on for 1 second and then it returns to off status. The same is done to the "close relay button".
There is a Lua script that close/open the relay during the interval that the virutal buttons are on.

The solution works well, except for the delay in the dashboard response.
The delay is about 10 seconds and I was not able to make it shorter.
Is there some settings where I could redefine this delay?

Thanks.
