Cannot get my Nexa switches/dimmers to work

Anyone care to help me through setting up my existing dimmers and switches? It would be greatly appreciated!

I tried following the info in the last two posts in [url=http://forum.micasaverde.com/index.php/topic,14695.msg111435.html#msg111435]http://forum.micasaverde.com/index.php/topic,14695.msg111435.html#msg111435[/url], but it didn’t work. I can see two dimmers, but they won’t do anything.

Now, this is what I did.

  1. Set the RFXtrx controller to autocreate=0 in order to not have the interference.
  2. Added AC Dimmers, one with Remote ID 260 and one with Remote ID 262. I gave both Unit Code 1.
    …after a reload, they’re both visible under devices…
  3. Checking under options, they both use D_DimmableLight1.xml but have different IDs. I find that strange as they’re two switches on the same physical unit (two way dimmer). Anyway…who am I to judge? :wink:
  4. Pushing buttons on the physical unit does nothing - except for turning on and off the nexa receiver paired to one of the buttons. In other words, I know it’s transmitting.
  5. Setting up a scene with triggers for both physical buttons. One for on and one for off. To be abolutely sure I see what’s happening I set it to turn off my office light. Annoying enough to be a good test. I also set an alert to my mailbox.
  6. Clicking the softbuttons under devices (either on, off or the slider) on any of the physical buttons now turn off my office light and I get an email. Pushing the physical buttons still do absolutely nothing.

Any other idea to what I can do? I imagine I’m very close, only missing one or two stupidly easy steps along the way :wink:

Cheers!

I’m having some trouble wrapping my head around what your setup looks like. Could you make a simple picture that includes all the senders and receivers in your setup? (if you mention what type of nexa devices they are could help also).

If you have 2 AC Dimmers created in vera you could see them as “sender” devices. Then you just need to put your nexa " receiver" dimmer device in learning mode and link your “sender” to your nexa “reciever”.

Thanks for the reply,

At the moment I’m only focusing on one type of switch, the LWST-605 (http://www.nexa.se/LWST605Vaggsandare2kanal.htm). I learned long ago not to mess with too many variables in a new system at any one time :wink: Both buttons are paired with their own dimmer module (http://www.nexa.se/CMR-100.htm) - this part of the setup works fine. I was about to say “flawlessly”, but there is a reason behind my upgrade :wink:

What I’m trying to achieve here is to get Vera to pick up on signals sent from my LWST-605 and do magic based on this. This will save me heaps on upgrades as new switches will set me back at lest $600, which would be a poor investment when I already have workign switches. The only down side is that I cannot pair them automatically with my Z-wave equipment, but if I see a need for that in the future I will replace the switches. But until then…I need Vera to pick up the signals they’re sending. That’s all, really.

If all you want to do is to pick up signals sent from your LWST-605 you just need to set autocreate=1 and when you use the switches, new devices should show up in Vera linked to your LWST-605. (Check that the AC protocol is enabled for your RFXtrx allso).

I “had to” set autocreate=0 because there seems to be a lot of people using Nexa in the building. I’m sure they’ve enjoyed me playing around with their lights in order to discover which unit’s which :wink: Anyway - with almost 20 unknown RFX devices (after I had found at least most of my receivers and plugin modules) I had to clean up my devices, so I deleted all of them, set autocreate=0 and then added them manually. With autocreate=1 they showed up as either remotes or binary light and I didn’t find a good way to distinguish between them. Adding them manually seem to work better. Guess I can try setting autocreate=1, play with the dimmer, then set autocreate back to 0 - but how do I change them to being dimmers from whatever xml they’ve been assigned?

The LWST-605 are not dimmer devices and should show up as binary light switches in your Vera.
I’m not sure how you could add the LWST-605 manually to Vera you can not put them in learning mode can you?

The Vera RFX Remote devices opens up other possibilities for the same device.
You get access to the different scene commands.

Here are the scene numbers to be used in a scene trigger:
– ON (activated) / OFF (deactivated): 1-16
– SET LEVEL: 17-32
– LOCK (activated) / UNLOCK (deactivated): 33-48
– OPEN: 49-64
– CLOSE: 65-80
– STOP: 81-96
– GROUP ON (activated) / GRUP OFF (deactivated): 100
– GROUP SET LEVEL: 101
– DIM: 102
– BRIGHT: 103
– ALL LOCK: 105
– MOOD1: 111
– MOOD2: 112
– MOOD3: 113
– MOOD4: 114
– MOOD5: 115
– PANIC (activated) / END PANIC (deactivated): 120
– ARM AWAY: 121
– ARM HOME: 122
– DISARM: 123
– PAIR (KD101): 124
– CHIME (ARC protocol only): 131-146
When a range of values is mentioned, it means the number depends on the unit code of the device (from 1 to 16).

Thanks :slight_smile:

Do you have an explanation to the different commands? What you’re saying makes sense - I just added them by clicking the AC button in the RFXtrx plugin and then played around with the buttons for a little while. When I saved, the switch was visible.

But - am I incorrect in assuming each physical button should show up as its own button?

I’m not so sure the Remote Device and the different scene commands are of any use until you actually “pair” one of the buttons with some “receiving” unit. Then it also depends on what scene commands this receiver supports. (I actually found that the nexa doorbell button sends a “Group On” (scene 100 activated) command so until I noticed this I could not get the doorbell to work in Vera)

For one LWST-605 you should get 3 separate devices in Vera, One separate binary light switch for each physical button/switch and one Remote Device.

I can be wrong about all this since I do not have a LWST-605, but I have a WBT-912 and I guess the behavior is quite similar… (I use one of the buttons as a Home/Away and the other one to manually turn on the lights outside).

Anyway if you find that my information is incorrect please say so :wink:

Hmmm…that was extremely inconvenient - and very expensive. I was hoping to have Vera pick up the signal from the wall switch and then signal the module to dim/on/off. I will be impossible for me to pair the Nexa switch and z-wave module :S

You should be able to turn on/off your z-wave device using your nexa switches trough Vera but dimming would be a challenge.
Do you really change your dimming level often? You can off course do whatever logic in vera to set different dimming levels in different situations depending on time of day or something and still trigger this from your nexa switches.

No, I only need on/off from the Nexa switches - but that kind of brings me back to my original question: How do I establish which one’s which?

I did not follow all the discussion but a general good principle is to:

  • Erase all child devices and reload the Vera
  • Then use your remote to switch ON one switch => this will create 2 new devices in the Vera
  • Wait for the automatic reload and then rename the new created devices
  • process like that for each switch

Thanks for all the help - I’ve given up trying to communicate with the wall switches. I’ve rather found that I can sell the Nexa equipment second hand and get some new z-wave modules and use some of them with my old mechanical switches to save some money :slight_smile:
