Please note that this Blueprint only works on HA versions above 2021.4.0


Blueprint for the HANK Electronics SCN04 4-button remote (more commonly known in Europe as the Technisat SCN04), using ZWave-JS

Designed to accommodate both “Press” and “Held” states of the remote and includes text descriptions of the buttons to make identifying them easier.

Credit goes to @Soccs for the idea in this post, and to @jei1965 for their minimote code which I used as a template

I’ve tested this with a couple of remotes, but if anyone finds any issues with this blueprint, please let me know.

Just what I was looking for! Thanks a alot.

Trying to get the Long Press action to dim up/down the lights, need to experiment a bit more.

amazing work! and amazing little control. no issues, just works!

@tjodolv Is this of any use ?

I have a couple of LIFX Candle bulbs in 2 IKEA SYMFONISK lamps, and here’s the code from the actual automation to change between warm white (45% brightness), and cool white (100% brightness) in 7 seconds using the “power” button.

      button_4_pressed:
      - service: light.turn_on
        data:
          transition: 7
          kelvin: 2700
          brightness_pct: 45
        target:
          entity_id:
          - light.lamp_l
          - light.lamp_r
      button_4_held:
      - service: light.turn_on
        data:
          transition: 7
          kelvin: 6500
          brightness_pct: 100
        target:
          entity_id:
          - light.lamp_l
          - light.lamp_r

Thanks p4mr! Really appreciate your reply.
What I was hoping for was that I could use the long-press/hold button for just the dim function. Where the short-press turns on/off the light (toggle). With the long-press I would like to be able to dim up to 100% and then when it reaches 100% dim down again.

Don’t think that’s possible.

You’d need separate “dim up” and “dim down” buttons. See this link for a code example of how to do that.

Thanks for clarification and pointing me in the right direction. Big thumbs up. Saves me a lot of time searching for an idea I have which is not possible. Thanks for taking your time to reply back p4mr!

Hi all,

I think that last update broke the blueprint.

I’ve tried to set it up after upgrade and I have no trigger.

I saw in the “breaking change” section something about a split in two categories of the zwaveJS events. Maybe that’s the case.

If i find time I’ll try tommorow to update this thread wiith my findings on the matter.

Yup, it did. I’ve had to roll mine back to 2021.3.4 as it broke too many of my Zwave devices and automations to resolve in one go. I’ll edit the first post to indicate the blueprint only works up to that prior version.

It looks like the fix is simple enough. Line 76 should be updated to:

event_type: zwave_js_value_notification

There’s some more details in the breaking changes post for the release.

Thanks @shabazkilla, you are right.

Have updated the original post (and code) to reflect the change and noted this Blueprint now only works on version 2021.4.0 and above.

Hi. Just found your blueprint while looking for my own HANK 4-button blueprint. I wish I’d found yours before working on my own. It was a good learning experience, regardless.

These scene controllers also support a KeyReleased event. Perhaps @tjodolv could use that if the mode was restart? There used to be an example in the old Cookbook page but it looks like it’s been changed to highlight blueprints instead.
