How to reuse Shelly Scenes with a webhook URL lovelace-button to an Shelly i4 device

NO: But I found out that you just can not re-use a scene that you have created on the shelly device/shelly-cloud. It is impossible.

So you have to choose:

  • create scenes locally on the shelly-device/cloud, or
  • create scenes on your home assistant server and use the scenes in Home Assistant automations (or scripts / blueprint-scripts) where you can use the triggers of the shelly i4 of 1P, 1LP, 2P, 3P for each of the 4 buttons

1P = 1 short press
1L = 1 long press
2P = 2 shorts presses
3P = 3 short presses

PRO’s for local i4 scenes: if your Home Assistant Server does not work, the i4 buttons still work (as long as your wifi is working).

PRO’s for HA-scenes with automations: a lot more advanced automation possibilities because of availabilety of the statusses of all your other devices in Home Assistant.

So your choice may depend on the advanceness of the required automations.

Other thing to consider: if you do half in local Shelly and half in Home Assistant, how consistent / clear will your end solution be? Too hybrid will cause you pain if you don’t know anymore on what platform you made your “automation”.

I do not know what you have found out so far, but the following sources may interest you:

NOTE: The original post was refferring to Shelly Plus i4 devices. You are reffering to your rollers which will problably be connected with a Shelly Plus 2 PM

So my answer might not entirely be applicable to the Shelly Plus 2 PM.
