Random (pseudoRandom) needed

[quajetson]

Any options to get random value in Rules?

[grovkillen]

Nothing right now. Could you please fill me in on your use case that makes you want a randomized value?

I need randomly play mp3 on trigger.

I'm doing speaking head

but playing always hard programmed mp3 sequence is not funny.

Ok, makes sense. Please open a feature request on GitHub.

Suggested command:

Code: Select all

Random,<lower>,<upper>

Where <lower> is the lowest randomized value and <upper> it the highest randomized value wanted.

And possibly also able to store to internal value like this:

Code: Select all

Random,<lower>,<upper>,<store 1..16>

And you the will be able to use it with %v1% ... %v16%

I need randomly play mp3 on trigger.

Is this trigger time based?
If not, i suggest an ugly temporary workaround:

Seconds based fake-random if NTP enabled:
((%syssec%/59)*(upper-lower))+lower

For example the following will give a number between 1 and 17:
((%syssec%/59)*16)+1

The result can be stored in a Dummy variable device with Taskvalueset, and also on the Dummy device page, you can care about digits.
taskvalueset,1,1,(((%syssec%/59)*16)+1)

I think it also can be combined with %rssi%, %sysload% and %sysheap% to be "random"-like but i am lazy to implement.

That's a nice try and would perhaps work in some cases

Solved with Dummy device and increment his value with 1 second timer:)
So this is not random but make step needded to play various mp3 or do other actions different way:)

Thanks enesbcs, Your solution is helpfull too:)
