Openhab2, Z-Wave2 is using Aeon Labs Aeotec Z-Wave Z-Stick, Gen5 (ZW090), on CentOs7.
Only issue with installation was the attempt of the software to put lock on the device under /var/lock/LCK…ttyACM0 - if you run it under ‘openhab’ user you have a problem with access as all locks are under /run that is re-spawned and owned by root after each restart - bottom line it was easier to run whole thing as root, after that all worked fine.
Devices in the mesh: WS15Z-1, WD500Z-1, WO15Z-1, ZOOZ ZSE40 sensors, DSC27103 dimmers, DSC26103 switches.
Total of about 24 devices on the z-wave, out of whole mesh 3 give intermittent messages like ‘NODE 6: Got an error while sending data. Resending message’ in the log, I think it is location specific as all works fine and all is responsive.
An absolute best device so far is the DSC27103 dimmer. It is a pain to make it fit into the wall behind the existing switch but it allows very easy install to control your existing 3way light switches. I had big hopes for DSC26103 switch as i do not need dimmers everywhere but unfortunately it is a bad device, its triggering scheme is too sensitive and if you use it on long wires in 3way setup the interference from AC wires is enough to mess up trigger so it works sporadically and sometimes jitters with very loud clicks, So DSC27103 is the only device that you can put into your existing 3way setup with keeping old mechanical switches and it only needs 1 DSC27103 to make it work. Downside - it does not like dimmers, at least i could not make it work with an old dimmer for a trigger.
ZSE 40 sensors are finicky a bit - a trick to make it work well is NOT to activate it until you decide where it has to live. Move it to the spot, then put in battery, link with the stick and leave it be. Then it will be responsive. If meddled with or moved around it may stop communicating and with one it was so bad i had to unlink, reset and re-link it back to make it work again. Other than that - excellent sensor, motion detection works in nearly pitch black, response time is about 3 sec or so - fast enough to put on porch light when i step out. It is not waterproofed, so you need to mount it where it will not get soaked.
What really surprised me - i did not find any device on the market that would have combined motion sensor with a dimmer switch to be installed in the wall instead of the old dimmer. There is a ton of non-smart non-Z-wave switches and dimmers with motion detection but i found none that would have z-wave and sensor and dimmer in the same shell and it is very odd as that is all i needed, really, in the house - for the light switch to sense if anybody walks by. So for now i had to put several ZSE40 around - it works, but it is battery dependent.
