Presence detection: OFF-ON-OFF when leaving

[MrMontesa]

Hey, I'm using the presence detection to activate my alarm system. When alarm system got activated I receive a OH popup. When leaving home I properly receive a "leaving message". 3 mins later, while still absent alarm system goes off. And another 3mins its activated again.

When looking at the events.log for my MAC presence detection items, the switch item indeed toggles to OFF when leaving. But few minutes later it becomes ON again and another 3mins later switches properly to OFF. From this morning when I left for work:

2016-07-19 07:15:23 - eg_flur_fbox_sepp_handy state updated to OFF

The question is: Why it becomes ON again while I'm definitvly not at home? Any idea how I can troubleshoot this in more detail?

These are my system details:

• OH 1.8.3 with 1.8.3 binding installed via apt-get
• Fritzbox 7490 with 06.51 installed
• binding refresh rate is set to 60 seconds as you can see from the logging
• behavior applies to all mobile phones I do presence detection for Let me know if you need more info. Thanks much
