Possible to control Somfy RTS device with Shelly i3 synced?

[mngsps]

Good evening together :-)
I would like to control my somfy blinds with a Shelly i3 Button (works) and would love to have this synced in HA.
However, I'm not sure how to configure this.

This is my cover in configuration.yaml:

- platform: cover_time_based_synced devices: rollo_time_based_synced: name: Innenrollo zeitbasiert synchronisiert travelling_time_up: 31 travelling_time_down: 31 close_switch_entity_id: switch.rollo_wohnzimmer_links_close open_switch_entity_id: switch.rollo_wohnzimmer_links_open send_stop_at_ends: False #optional

But how to set the switches? Since the i3 itself does not implement switches, I tried to use template switches:

rollo_wohnzimmer_links_open: friendly_name: Rollo Wohnzimmer links öffnen turn_on: - service: cover.open_cover entity_id: cover.innenrollo turn_off: - service: cover.open_cover entity_id: cover.innenrollo rollo_wohnzimmer_links_close: friendly_name: Rollo Wohnzimmer links schließen turn_on: - service: cover.close_cover entity_id: cover.innenrollo turn_off: - service: cover.close_cover entity_id: cover.innenrollo

These switches will be controlled with the i3 as automations:

`alias: Wohnzimmer schließen
description: ''
trigger:

• platform: device
  device_id: d912c908fc8a63978d0a939a7c3d2dd4
  domain: shelly
  type: single
  subtype: button1
  condition: []
  action:
• service: cover.close_cover
  data: {}
  target:
  device_id:
  - 07359d81edcd8cf1b81c57ba4a1ade39
  - 6c3e4b37ec1ced21e4bee910881025b8
  mode: single`

and

`alias: Wohnzimmer öffnen
description: ''
trigger:

• platform: device
  device_id: d912c908fc8a63978d0a939a7c3d2dd4
  domain: shelly
  type: double
  subtype: button1
  condition: []
  action:
• service: cover.open_cover
  data: {}
  target:
  device_id:
  - 6c3e4b37ec1ced21e4bee910881025b8
  - 07359d81edcd8cf1b81c57ba4a1ade39
  mode: single`

Its working and I guess myself is the failure :-)
Any Idea how to set this up for me?
All the best and kind regards to you!
