I’m migrating to Home Assistant and Z-waveJS. I understand that for most of my devices I should not use secure inclusion, but that for the Z-wave device controlling my garage door I should use it.
I could not find some checkmark in ZwaveJS to confirm that I included the device securely. Therefore I shut down the ZwaveJS addon and opened the ZwaveJS2MQTT addon and checked the status there:
Does the fact that it says ‘NO’ mean that my device is not added securely, or is ZwaveJS2MQTT somehow not able to read that I added the device securely using ZwaveJS?
Since the ZMNHND is not an actual “garage door opener” device (as defined by the zwave specification), there is no requirement that it supports the Security command class. If this is your device, the manual linked there does not mention anything about secure inclusion or support for the Security command class. If it’s not supported, it can’t be included securely. You would want to confirm that.
I installed this device on my garage door controller 4 years ago. I feel a bit silly now but thanks a lot for making me face reality @freshcoast.
In the manual of the device they show as some of the main use cases how it can be used to control doors, ports etc. so I could not imagine it doesn’t support secure inclusion.
I guess the risk of someone coming here and hacking my garage door is tiny, but it’s still not a very comfortable feeling.
Perhaps I should start looking for an alternative zwave device with a potential free output (aka dry contact) that can be powered from 24V or 12V?
Thanks again
I agree, the risk of someone hacking your network is pretty low, however for things like locks or GDC I prefer to err on the safe side. There are other relay products out there that support Security. For example, here’s a Zooz garage door kit.
Are you using the relay for other purposes besides the garage door? If not, there are always the dedicated GDO devices.
No this zwave device’s only function is to open/close my garage door: I configured it to make a connection between two dry contacts on my garage door controller for 1 second. That will open/close my garage door.
The garage door installer placed a wireless button on my wall to open/close it and gave some wireless keyhangers. So there are no wired switches to tap into for these dedicated garage door controller you refer to.
I was thinking this Aeotec device could be an ideal replacement as it has secure inclusion, seems to have a potential free output and can be powered by 24V (my preference as the garage door controller provides 24V). However it doesn’t seem to have a configuration parameter to automatically turn the relay back off after X (milli)seconds. I could program this in a home assistant automation instead but this garage door shows strange behaviour if I don’t set the number of millliseconds that the relay remains closed quite precisely
