The preliminaries:  
Homey Pro early 2013 version 12.1.2  
I am having problems with the attached flow  
[Test Flow|640x93](upload://qIvvJGWx4lMH1iGL1DSZAQOfa3h.jpeg]  
It is a very simple flow…  
A short push on the momentary button 1 connected to the Shelly i4 should turn on a group of lights, the problem is that it doesn’t.  
I also have a flow to turn the lights off, double push button 1.  
Testing the two flows from the desktop app works.  
When testing with the button no response.  
I have checked the Shelly i4 it is wired correctly and has power at all times.  
Any help will be appreciated.

I have the same problem. I testing simply flow with shelly i4. When I toggle the switch nothing happens. How do I set up Shelly i4 please?

I may be barking up the wrong tree, but I would try to configure the switch to operate in “detached mode” in the Shelly app.

Volgens mij heeft een i4 geen detached functie.

Je kan een webhook proberen: shelly app \> actions \> … \> url: [http://xxx.xxx.xxx.xxx/webhook?event=test](http://xxx.xxx.xxx.xxx/webhook?event=test)

Homey: Als \> Logic \> Webhook evenement test is ontvangen

Translated:

I don’t think an i4 has a detached function.

You can try a webhook: shelly app \> actions \> … \> url: [http://xxx.xxx.xxx.xxx/webhook?event=test](http://xxx.xxx.xxx.xxx/webhook?event=test)

Homey: When \> Logic \> Webhook event test is received

( xxx.xxx.xxx.xxx is IP-adres of your Homey)
