For my roller blinds from Jarolift, I am using the dedicated cloudbox with the app and webservice from Everhome. Everhome is providing a API interface, but unfortnatally I am not skilled enough to implement this in my Home Assistant.
The support from Everhome posted a comment, it should be easy to connect Everhome with Home Assistant with following informations:

Is there a wise pro, who can help in this integration?
