Events Sleep/Wait command

[SilasAT]

Hello, we want to control a heater with the help of eventes (Blockly) but we are missing a Sleep/Wait command were we can define how many ms or seconds we want to wait before proceding to the next block. All help would be appreciated.

you could create an extra dummy switch with a switch off delay and use that in the next 'else if'-block

[Egregius]

Or you use php for scripting. Usleep and sleep are standard functions for microseconds or seconds wait time.

[SilasAT]

Can you explain how these methods works?

[Egregius]

You mean in PHP? Simple, just add sleep(5) where you want the script to sleep 5 seconds. Or usleep(500000) for half a second.
But that requires that your whole script is in PHP offcourse.

But we are creating it in the GUI So can we make a combination of php and GUI?

Hi, I've been trying to understand this myself lately. I realise putting delays in LUA scripts is not recommended but is it OK to put delays in a php or bash script (for example)? This won't block DZ from processing other requests will it?

What's the recommended approach for putting delays between device calls?

Thanks.

I have a similar problem and maybe we can get an answer that suits us both...

My 1-wire counter seemes to post the same thing twice with in milliseconds. This makes my LUA script trigger twice and destroy my actual watt calculation. Gaaaah, why is 1-wire posting twice and why can't I use the sleep function I have tried in my LUA script ?

Never mind, didn't work well
