Hello OpenHAB Community.
I’ve been researching HA for the past few weeks and I have a bit of an odd setup I am trying to plan out and could really use some advice from the community on how to approach this.
Originally I was looking into using homeseer because of the z-net ZWave to IP interface that they have available., but I prefer OSS solutions wherever and whenever possible.
I need to place a z-wave antenna in multiple office locations, each office is networked together through a routed OpenVPN setup.
I will install OpenHAB on a virtual machine that does not have USB or hardware-passthrough, using a usb z-wave stick is not an option because it limits me to one singular location and needs to be plugged into the VM host.
I would like a z-wave to IP antenna device installed in each location, communicating back to the openHAB Virtual Machine server via the OpenVPN VPN Connection, so I can then use the one openHAB instance to control sensors in the various geographically separate office locations, and have one interface/mobile UI to control the devices in multiple locations.
I’ve read various things about people using wink or vera hubs instead/in-place of z-wave to usb sticks to do setups like this, I’ve also read about people rooting the wink hubs.
I’ve also seen a mention of using a USB over IP device, but this seems overly complicated and prone to possible reliability issues? Not to mention not tested.
What direction should I be heading in my research and planning here? Can I use a wink, vera or other hub with openHAB the same way that the z-net IP-Zwave device works with homeseer? are there any limitations to using a hub to communicate with the z-wave devices vs. directly communicating with them via a z-wave usb stick? Are device states reported just as reliably either way? does it introduce lag or reliability issues? Does it limit what kind of z-wave devices or sensors I can use, etc?
I could in theory place a Rpi in each location running separate instances of openHAB, but I am trying to avoid this, and it seems that placing just a hub in each office location that connects back to the main VM server via the existing openVPN connection would dramatically simplify things, it would also make it simpler to create rules or actions that use sensors in multiple locations.
What limitations or gotcha’s am I going to run into going this route? What hardware should I be looking into? Should I even be looking to go in this direction? Would separate Raspberry Pi’s in each location reallt be a better option?
Also I’ve read that openHAB can not do z-wave PLUS / z-wave gen5, and that openHAB can not do z-wave security class devices like newer z-wave door locks, is this true? I thought sigma just openly published the z-wave spec, is this going to change soon?
I also read that OpenHAB can’t do as much with zigbee, is this true?
Thank You so much for any assistance or guidance, I am just getting started here and want to fully understand the limitations of each HA platform before I fully dive into and dedicate myself to learning one.
