This overviews adding a Zooz ZEN34 smart switch to Home Assistant and using it to trigger automations.
This guide was written for HA 2021.6.6.
- Home Assistant
- Z-Wave USB Hub
I recommend either the Aeotec Z-Stick 7 or Z-Stick 5.
- Z-Wave JS integration on Home Assistant
See setup instructions here.
- Zooz ZEN34 Smart Wireless Z-Wave Switch
Add ZEN34 to Z-WaveJS
- Remove paper battery tabs from switch to power on switch
- Login to Home Assistant
- Go to Z-Wave JS and press “Add/Remove Device”
- Select “Secure Inclusion” and press “Start”
- The switch should show up on the Z-Wave JS Control Panel.
If the fields are fully filled in (they shown “unknown” or “dead”), wait 5 minutes.
If the fields still haven’t shown up, press the upper paddle 7 times to force the switch to wake up and send/receive configuration data.
Listen for Switch Presses
The switch should show up as a device under Configuration->Devices. Unintuitively, the switch will not have any entities for the two buttons, but just entities for battery status.
When the switch is pressed, a
zwave_js_value_notification event is generated. The event contains data about which button was pressed and how many times it was pressed. To use the switch for an automation, we will use this event as the trigger.
- Go to Developer Tools->Events
- Under “Listen to events”, enter
zwave_js_value_notificationand press “Start Listening”
Note – you can also enter “*” to listen to all events.
- Press a button on the switch. You should see the event appear.
The important data are
device_id– identifies the switch
label– “Scene 001” = upper button, “Scene 002” = lower button
value– how many times the button has been pressed
We can now use this data to trigger an automation.
Trigger an Automation
- Go to Configuration->Automation->Add Automation
- Under Triggers:
– Trigger Type:
– Event Type:
– Event Data (from the “Listen for Events” step) :
- Add the rest of your automation’s conditions and actions.
List of Event Data
The ZEN34 switch supports multiple presses (up to 5 presses) and long holds.
