Thanks Sihui for clarifying this - it will help. I think there has been some very useful discussion despite/potentially because of the confusion, though. While the parameter number may change for the dimmer, the notification codes should be applicable for the dimmer (LZW31) as well.
@roy_liao - I mean for the LZW30 , not the LZW30-SN. From your rules/description, I believe you probalby have the LZW30-SN - with the scenes. The zwave binding currently available has the first iteration of the specifications - without the LED notification parameters. Iāve since updated it, to test this in the LZW30, but as Chris is on vacation, I havenāt been able to get the updated snapshot yet. In contrast, the current zwave binding snapshot does have a functional LED notification parameter for LZW30-SN.

Ah, got it. Yes, youāre right. I have this working on the LZW30-SN (RED), not the Black series.
Hi Bruce,
This is Adrian and Iāve been playing with OH2 (v2.4 stable) for a little while and I love it! Sadly shortly after success with some other switches, I bought one of this LZW30 switches, and I was wondering what is the best way to get this into my OH2.4 (without leaving the stable) I read about installing the 2.5 Snapshot, or manually installing the specific device into existing binding but cannot make it workā¦
Do you mind sharing a link on the best way to stay with stable but get this switch supported? (if possible) Iām on Debian x86, and installed OH 2.4 from repository
Thank you very much!
Adrian
See Manual Z-Wave Installation
Also, if doing it completely manually, I occasionally revisit my summary
The first half could likely be ignored, but if you run on a raspberry pi, you can follow my second half almost verbatim.

Thank you very much! Iāll check it out after work and let you know how it goes (for sure success!)
Hello
What will be a good switch to implement with Openhab?. I am looking for a on/off switch WiFi or Z-wave, no Neutral Required. I will be controlling LED lights. Is the Inovelli LZW31 will be a good choice?
Thanks,
Menachem
No neutral required will be a difficult requirement. Generally, the only switches that Iām aware of that donāt require a neutral wire are dimmers (the switch has to power itself, and dimmers just steal a little bit of power slowly, too little to actually result in the lights coming on. This may be a problem for LED lights, which donāt require much current at all to turn on.
A neutral wire allows the switch to take the current form the line (generally black), and send it back the neutral (generally white), rather than having to send it forward around the circuit to the light. Without a complete circuit, there is no power for the switch to be listening to zwave/wifi.
==
If you do have a neutral wire, there are lots of options. the inovelli LZW30 is a well-priced option, but it is only in the 2.5 and later zwave binding - meaning that you will need either to manually install this binding, or wait for the stable openhab 2.5 to be released. Zooz also puts out reasonably-priced z-wave switches. If youāre going with z-wave, make sure you are getting the correct one for your region (different world regions use different frequencies).
You mention the LZW31 - this is a dimmer switch, not an on-off switch. The dimmers are still only part-way through shipping pre-orders, while the on-off (LZW30) are shipping to the public. So far the LZW30ās have been solid for me. I suppose if you know you donāt have a neutral wire, you could use the dimmer LZW31, just as either on or off (0 or 100 via openhab, or short presses on the switch). You may run into problems, though, if you press and hold the switch, which would normally start the fading process either up or down.
I probably can use Smart Wifi E27 Light Socket
Thanks Ben,
The problem is that I do not have neutral wire so I am limited with what i can use.
So the LZW31-SN will do on/off?
Can you explain what problem you think I will have.
Thanks
Menachem
Hi Ben,
Iām in openhab installed in debian, and at first the script failed (missing curl) Even after that, was still giving me errorsā¦ But I was not going to give up! In the end I temporarily changed openhab user (so I can do su - openhab and get a shell command) and I did install in steps, the serial transport first, then disabled the zwave, finally install the snapshot one (all using your script).Iām a very happy user of LZW30 switch now thanks to you!
Have a great week ahead
Adrian
Thanks, but the real credit goes to 5iver, whose script it is. Several others with far more knowledge than I have helped as well.
I only compiled the various suggestions others have made, into one location.
Iām glad you had some success!

The dimmer may possibly burn out a bit quicker, or the bulb may flicker if a non 0% or 100% brightness is inadvertently be chosen. You may accidentally move to a non 0/100 value by pressing the switch too long. That should be about it. Your programming in rules can easily set it to 0 or 100, but just setting it to ON (I believe) may set it to the previous brightness - so it may be a good idea to use .SendCommand(100) vs .SendCommand(ON).
One quick question related to my LZW30 successā¦ I added three of these switches wishing they were going to extend my zwave network, but other battery devices donāt seem to use it as a gatewayy (I have a full ticket with network diagram and more - Please help! Set up of a small school with OpenHAB)
Is there a way to āforceā this switch to route messages? Or the other battery devices to see the switch? They are very near (less than 10 ft) and still try to connect to the far away HUBā¦
Any hint will help. Thanks!!!
Adrian
No. Routing is autonomous in a zwave network - you canāt influence it. All devices that support routing should find the most appropriate route to the destination - thereās also nothing you can change in the end devices either.
How do you know that? Iām not aware of anything that shows what routes are being used?
Thank you for the information. What Iām looking for the second point is habmin information on the zwave diagram, that seems to show nearby devices donāt connect to the light switch that is just across the hallway (I tried to put the complete diagram and information on my original post here Please help! Set up of a small school with OpenHAB)
Thank you Chris for taking time to help me out!
Adrian
The HABmin diagram doesnāt show routes - it shows neighbours. Now, Iām sure youāre probably thinking that the neighbours list would be a superset of the routes being used, since a route canāt exist except via a neighbour, butā¦
The two things (the neighbours list and the routes) are probably separate - I say probably as it depends on the generation of the devices being used. If the devices are reasonably new (letās say, ZWave+), then routing is normally undertaken by a device searching for routes using whatās called āExplorer Framesā. If the devices in this area of the network are older devices, then this may not be supported, and then the routes are chosen by the controller, and I believe that this configuration will use the neighbour table. The binding just tells the controller āconfigure a route from node A to node Bā - thereās no control over how the route itself is derived.
Iām not sure that helps much, but hopefully it provides some insight at least 
.
That is great info! this is my (very horrible) diagram of the school, that is a long hallway. The classrooms that cannot connect (with Gocontrol zwave devices - battery powered) are the ones on the right of the diagram (G8, G6, G9, G7), even if they have the LZW30 (node 12 - electrical switch) very near to them.
When I bring the Gocontrol devices (G8, G6, G9, G7) near the Openhab z-wave master controller, they connect without any troubleā¦
What Iām trying to understand is how to fix this firstā¦ Should I move the server to a central location? (nothing easy maybe I can put the server temporarily in one of the classrooms) - Add more electrical switches? (another brand so they actually repeat the signal)
I tried to enable debug log, but those messages mean nothing to meā¦ Should I upload some?
I feel bad that Iām using your time but I do appreciate your help very very much!
I think maybe weāre getting off topic of this thread, so Iāll respond on your other thread.
One quick question about the LZW30 Inovelli switches - does anybody has experience on how to remove them from the zwave association when they are not recognized properly into openHAB? Do you remove them from their reset option? (20 sec press of the config button?) Any hidden switches or not documented features? And then how do you remove them from the controller tool? Using windows tools?
Thank you very very much!
Adrian
