I prefer regular existing wall switches. You can add a spring to make them monostable.
You will see in openhab when you press the physical button on the wall, the status in openhab should be updated, otherwise you have configured it wrong.
Basically you are wrong about the status in OH. If you use bistable or monostable does not matter the status is still updated in the OH GUI.
In my house I use all existing wallswitches, but I do have a couple of zwave.me wallmotes as well. Think they cost about 40euros and comes with a CR2012 battery, didn’t manage to find any but the popp one is similar: https://en.m.nu/remotes/wall-controller-2
I think the first configurations you posted may be general. Parameter 1 mentions 2 different options depending on whether the device is a switch(binary) or dimmer(multilevel). This device is neither. but I see it listed as parameter 7 anyway (?)
I think we can safely use the later settings. They basically agree with the manual on OZA and the configuration used by OZW. OZW also groups the 2 devices in our entry together.
EDIT: Please delete the options for parameter 1. I labeled them as “remove”
EDIT2: Ready for review after parameter 1 options are removed.I will not request review in the database at this time.
I have the single channel version of the z-wave Neo wall switch (UK/EU version) in use for ~12 months. Working fine with openhab 2.4.
I’ve not had issues with the motion sensor FWIW, but perhaps there are different models. I do know the instructions didn’t match the device (which seems a common theme!) but does work fine for me with openhab.
If you are in the US region, I prefer Zooz.
Actually my first switch developed a physical switch issue and they replaced it with a pre-tested unit very quickly. I have 1 Zooz connected with a conventional switch to control a staircase light from 2 locations.
