Capability against electronic jamming equipments
Electronic jamming equipments are easy to use against Z-waved system.
Then your security system becomes useless.
It could be interesting if the zipabox could included a capability to detect such a jamming.
For example, in an certain mode (alarm mode), with this capability activated, the box would try to detect one or several zwave devices (not on battery) every 2min (param. delay).
If not responding and if the box not on battery, so this is not a voltage interruption, the box could launch a scenario (mail, tweet...) and eventually activate a wired device directly connected to the box (siren, flashing light)
