How to animate random property every x seconds with an interval(hold) duration?

Trying to animate y position at random, whereas the position change every second but the animation from the current y to the next takes half second. So the y stays put for 0.5 sec in between.

ex:
- animate y from 12 to 44 during 0.5 sec;
- stay at 44 for 0.5 sec;
- animate from 44 to x during 0.5 sec;
- etc

Similar to wiggle but adding an interval between each cycle.

Tried using seedRandom and posterizeTime but it will just snap from value to value, and I'd like it to ease in out and stop for a while. Does that make sense?

Thanks in advance.

Something like this maybe:

segDur = 1;
minVal = 0;
maxVal = 100;
seg = Math.floor(time/segDur);
seedRandom(seg,true);
curVal = random(minVal,maxVal)
seedRandom(seg-1,true);
prevVal = random(minVal,maxVal);
t = time%segDur;
ease(t,0,segDur/2,prevVal,curVal)
