Lag problem with motion sensor

Hi!

I have this: Nexa SP-103, motion sensor. Its on z-wave.

Its working 100% with Telldus, i get motion noticed right away, but its some lag problem to HA, i dont get noticed right away when a motion i triggered, it can take several hours before HA noticed the motion.

I also have this: Nexa MIMST-1703, it on 433 mhz. Its working flawless in HA.

What can the problem be? Why is Nexa SP-103 laging? I have like 3 meters from telldus, so no distance problem, and as i said. Its working flawless in Telldus, it must be some problem between telldus and HA.

Thanks for all help!

Any ideas?
