Hello Jesper,
Here is a blog on alternatives for IFTTT for your reference.
Have you already tried Home Assistant for these use cases?
You would need to add the Bridge via the API to the HomeAssistant, of course, connect the Smart Lock & Opener to the Bridge, and then create automations for it.
The first use case should be possible i.e. if ring to open is activated, then smart lock should open/unlock. But the “lock n go” use case is not possible via this method.
