Aeotec Nano Dimmer (ZW111) Control devices from S2?

Configuration
1

I have a Aeotec Nano Dmmer (ZW111) and I’m trying to get the S2 switch to control the lamps in my living room. They are a mix of Z-Wave and Sonoffs (MQTT), and I can’t seem to find any way to check in Home Assistant if the S2 switch has been flipped. It seems that all that I can do is set up to 5 Z-Wave devices to be turned on/off by the dimmer. Is this correct? If so I’m going to send this back and replace it with the Fibaro dimmer which, from my understanding, can do what I’m looking for.

Maybe a bit late to answer your question, but I also had this question earlier and had no luck searching the internet for an answer. However I did manage to get it working -

  1. Select the dimmer on Z-Wave node management.
  2. Select Group 4 (Control Key2) on Node Group Associations.
  3. Choose your Z-Wave stick (AEON Labs ZW090 Z-Stick Gen5 EU in my case) and click add to group.

This will make a z-wave event fire in Home Assistant which you can catch with an automation to control other devices.

Hopefully that’s useful to anyone else looking, even if you’ve already replaced it with a Fibaro one.

That’s actually very helpful. I’ve ended up with a Xiaomi Aqara (still waiting for a Zigbee Pi sheidl to control it), but I still have the Nano Dimmer, so I might fire it up and try to see what I can do with it. Can you tell which switch was switched if you have multiple dimmers?

Glad to hear it.
I catch the event with this trigger. The entity id and node id will change between each dimmer.

Event type - zwave.node_event

basic_level: 0
entity_id: zwave.study_dimmer
node_id: 6

I am looking at adding dimmers to a new house, so want to make sure I buy the right ones. I have used Aeotec switches so far without issue.

With your zwave event, do you get separate events for both S1 and S2 on the dimmer, or are they indistinguishable?

I would like S1 to control the load and S2 to fire an event, primarily to activate an HA scene of my choosing.

I have exactly that setup. The event is only fired for S2, so no need to distinguish between the two.

Is that using the old Zwave implementation or OZW Beta?

It wouldn’t surprise me if this changes with the new implementation.

Update if anyone still finds this useful. This was using the old z-wave implementation.

This morning I migrated to zwavejs2mqtt, which went surprisingly well.

My fibaro dimmers exposed the S2 button, but again I had to catch this Aeotec dimmer S2 press with an event on “zwave_js_value_notification” using the nodeid again to differentiate it from the other Aeotec dimmers.

Not ideal, but it works reliably.
