Z-Wave Plus 700/800 Series S2 ZEN 71/72/76/77 Switches

I have the same dimmer and home assistant detected it as a ZEN77 800LR. You have to change the model number under input:

  input:
    Zen77 Dimmer:
      name: zooz-switch
      description: List of available Zen77 dimmers.
      selector:
        device:
          integration: zwave_js
          manufacturer: Zooz
          model: ZEN77 800LR

@muddro ,

Could you update the device filter to have ZEN76 800LR?

          - integration: zwave_js
            manufacturer: Zooz
            model: ZEN76 800LR

I just tested by adding this filter to your blueprint and tested with my own switches and can confirm it is working just fine for this model as well!

No problem. Done

This has been a fantastic blueprint, thank you.

I have Zen72 800LR switches and have modified the filter to support those and can confirm they work like the rest if you’d like to add that as a supported device:

        - integration: zwave_js
          manufacturer: Zooz
          model: ZEN72 800LR

I also changed the device selector to “multiple” and updated the condition to the following to allow for multiple switches that all will match a single automation and execute. My use case is multiple switches running without a load connected acting as remote 3-ways to control lights, so I want say 4 switches to all do the exact same thing with single/double taps.

condition: “{{ trigger.event.data.device_id in device_id }}”

Hi,

I want to use the Zen72 or Zen77 (Whats the difference) as a remote dimmer in a wall box (i.e. with no load). It will control another Zen72/Zen77 dimmer that is in another location (and connected to another controller.

So, I guess a few questions for you experts.

  1. What’s the diff between Zen72 and Zen77 (which one should I buy)
  2. Can they operate with no load – and just fire off and receive z-wave messages.
  3. Do I need to go via HS because they are on two different z-wave networks?
  4. What’s the latency like (i.e. press dimmer up on one unit and see the response on the other)?

Thanks in advance,

suresh

ZEN 72 vs 77 from what I can tell is in how they handle 3-ways. The 77 allows you to use your typical/existing wiring (mains voltage w/ 3 way switch output going to the load) where the 72 requires the 3-way to be re-wired to just communicate back to the switch using switched neutral/ground approach. I’m using 72’s for my remote, no load switches

Yes you can definitely operate with no load, you do have to set some configuration parameters to enable scene control and disable the relay.

Sorry can’t help on this one.

For my house based, same z-wave setup the latency is about as good as the 3-way approach, so ~200-300 ms It’s noticeable, but not long enough to cause someone to try and turn it on again or something.

I would also point out that if you are using a dimmer (regardless of model) to control another one, you would probably want to use the native zwave association for that, not a home assistant automation. Both would need to be dimmers and you would need to set up group associations in zwave js:

This method would have the least amount of latency I believe and work.

Thank you for the suggestions on updating the blueprint. I’ve enable multiple and added all 71/72/76/77 switches. I think that should cover it all.

So happy to have found this blueprint to save some time.
One thing I’m seeing that’s missing, maybe, is LED control. I have two Zen71 800LR switches and Zooz and The Smartest House documents make it sound like we should be able to trigger the LED to change colors (4 options), but I only see this in the parameters, not as directly controllable in automation. Even read some review of someone praising the feature using Homeseer. Any ideas?

Yeah, you’d have to do some research, but if its anything like my inovelli you can do it through an automation. Now whether you want that automation to be part of a button press or to alert to something outside of a button press, like an open door or lock, thats up to you.

I think the above post is slightly wrong. I was able to modify a zen30 using this:

Thanks for linking that. I’ll have to dig into it when I have some time and if I find it worth the effort. My switches aren’t installed in high traffic areas, but the feature may be useful.

I’ve played around in the past and used for when the front door is unlocked or garage door open for more than X minutes and things like that.

I’ve looked thru all the documentation but I must be missing something for my ZEN71 switches. It looks to be I’m having some issues with the trigger. Let me know what I’m doing wrong here.

You are looking at the wrong automation or you didn’t set the device.

See attached filled out blue print. Devices work outside this blueprint automation

Have you configured those switches for scene control?

I tried to change the toggle switch in the settings and it goes to the off position when I exit and come back in. Doesn’t show a confirmed saved message like other options either. Switches are also set for smart bulbs. Local and z-wave control disabled.

You may need to go to the home assistant discord for assistance on that or contact soo. For this to work you need to have scene control enabled (you may want to set the other parameter to only local disabled to test). I’d also try reinterviewing the switch and then try turning on scene control again.

This is a bug on Home Assistant with all toggle parameters that has been fixed but not yet released:

Is there a link I can use to add this blueprint?
