Hello,

Somebody know how it is possible to check the status of Z wave device, for detect Jamming attack ?
Maybe make a scene with luup code for poll Z wave sensor, if no answer sen a notification ?
I have a Vera lite, and if you know how made this i will very interrested.

Thanks.

For the detection of jamming attacks on your Z-Wave installation, use a spectrum analyzer.
If you’re concerned about security, Z-Wave mightn’t be the right choice.

A Z-Wave device that doesn’t answer doesn’t necessarily mean that you’re under attack.

MiOS provides an UPnP action ‘StressTest’ (service: urn:micasaverde-com:serviceId:HaDevice1) that could be used to ‘measure’ the quality of the Z-Wave signal. You could use [tt]luup.call_action[/tt] to call ‘StressTest’.

Thanks for your answer,

I understand, it is not very safe, but many new Z wave devices are made for Security control.
I just want to find the better solution for know if somebody use a jammer and send a notification.

@blooby78,
For that level of security/monitoring, you may need to use an Alarm Panel. A number of the [supported] panels will give “Tamper” events when a remote wireless device is having problems. I haven’t seen any Z-Wave devices [yet] that have that sort of functionality.

That said, these are often done by infrequent [sometimes configurable] polls for every device in order to keep battery usage to a minimum. I suspect you’ll burn batteries in any kind of device if you attempt to poll them, at any meaningful rate, for “presence”

There are a few threads on burning up batteries in various Battery powered devices by folks (or Vera) that poll them more frequently than the device intended.

I know about it, DSC is better (but very expensive), but now you have a lot of Z wave device for security. I just would like a little script for check the status of device (reachable or not) and send notification about it.
Nobody can help me ?

@blooby78,

Welcome!

Are you looking to check the status of battery-powered Z-Wave devices, like a door/window sensor or motion sensor?

If so, chances are that the device is normally sleeping, so polling it would fail, and therefore not necessarily indicate an issue (as @Ap15e mentioned). Such devices can be told to wake up more frequently to ‘check in’ with Vera, but that would drain the batteries quickly (as @guessed mentioned).

Hello,

Thanks for your answer.
I have only ask how it is possible to check the result of poll node? I would like to make this test on other product (not sensor, but dimmer), if your are jamed all devices will go down. It is better to check a device who is connected on power.
Please provide me the luup code for know the poll resutl and send notification if is no answer.

Nobody can help me, regarding this luup code ?
