Fibaro Smart Implant to control garage door. Momentary switch?

Questions & Help
1

I’m using a Fibaro Smart Implant connected as a dry contact (NO + COM) to the wall button input on my garage door opener. It works fine, but I would like the relay to behave as a proper momentary switch with a short pulse (around 0.3–0.5 seconds).

In Homey I can only configure:

  • Output mode: Normally Open / Normally Closed

  • Flows with a delay, but the minimum delay is 1 second

I can’t find any option for sub-second auto-off or pulse duration in the device settings.

My questions:

  1. Is it possible to configure <1 second auto-off for Smart Implant directly in Homey?

  2. Is this dependent on firmware version?

  3. Is there a specific Z-Wave parameter that allows setting a 500 ms pulse manually?

  4. Or is everyone simply using a 1-second pulse and accepting that garage door controllers don’t really care about the exact duration?

I would prefer not to buy a Fibaro Home Center just to update firmware for a single Smart Implant.

Also, I’m curious how others here have solved garage door control in Homey:

  • Are you using Smart Implant, Shelly, Qubino, or something else?

  • Are you relying on software delay in flows, or hardware auto-off?

  • Are you combining it with magnetic contact sensors for open/closed status?

  • Any best practices for safe and reliable control?

Thanks in advance for any advice :+1:
