So mine should be:
20,2,2;156,1,1;21,1,2;157,2,1
20,2,2= monostable button (2), monostable button (Central Scene) (2)
156,1,1= auto off enabeled (1)?, auto off at 0.1 sec (1).
21,1,2;157,2,1= is this even needed if I don’t have anything connected to output 2?
Looks like you are using the wrong size.
20,1,2;156,2,1
I don’t think you have to program the other one. Why did you do so?
I took a look in tools.developer.homey.app/tools/zwave and I see that the “TX queued” and “TX sent” is counting up:
It stopped at 270 and 295 after a few minutes after the last input I did on my phone related to the SI. It also states that there is 6 (2%) Tx errors…so I’m starting to think I might have connectivity problems on top of the configuration issues.
Monkey see monkey do… 
I’m just copying stuff I find in this thread… 
I’m having a really hard time to get my head around how this works (I’m a little cognitively challenged when it comes to reading instructions due to a medical condition).
Ok, why I showed info for both:
I just showed stuff for both in- and outputs for it to work regardless of which is actually used. And to eliminate
possible misunderstandings.
And it’s not a days work to enter the code for the other output 
It’s up to you what you use in the end.
Maybe your gate needs a little bit more then 0,1 second pulse? For example 0,5 seconds.
Fair enough 
Hi. I setup the same logic for my ancient SEA Orion gate motor that used to have a 433MHz receiver sending an impulse.
Parameters for the SI: 156,2,5 on Normally Open.
Then a basic Flow: When Flow started Then Output 1 On, Output 1 Off delay 1sec
That emulates a Impulse and it works well!
Thanks for the tips
P.S : It would be great to have Homey enable the option of an impulse without needing the Flow.
Homey doing things ends somewhere… at some point we have to build flows to get things going 
Very true: you have to go with the flow
Better use 1 second for push-button simulation, these input mostly have bounce elimination to prevent double pulse.
This is the connectors on my garage gate:
This is from its manual:
This is how I have connected it (P to 3, GND to 1 and OUT1 to 1)
I have also added the following raw config for the Smart Implant in Homey:
20,2,2;156,1,10;21,1,2;157,2,10
Does anyone have any idea if it’s connected incorrectly or anything, as nothing happens when I press on the smart implant in Homey. I do get the temperature updated every few min from Smart Implant, so its communication with Homey is fine.
I assume that your garage door will open/close when you close the circuit across pins 1 and 2 for (say) 0.1 secs. If so then you need to wire OUT1 to pins 1 and 2 on the garage opener. Then when you switch OUT1 and configure it to provide 0.1 second pulse on OUT1 your garage should operate. Not sure why you have done this - “GND to 1 and OUT1 to 1” although even then it probably should have said OUT1 to 2.
Anyway what you have done looks wrong to me.
These (20,2,2;156,1,10;21,1,2;157,2,10) also look wrong, but then you didn’t say what you were trying to achieve with these settings. If you are trying to change the time the contacts stay closed then they would be different. I assume you would need to contacts normally open. Therefore 20 and 21 to 1.
