Unfortunately this is not possibile as far as I know. I opened a topic about this some time ago, it has 14 votes and still ignored by EweLink/Sonoff. It’s all about administration rights. Only the administrator can receive push notifications by scenes and only one administrator is allowed per installation (there’s many topics with requests about sharing homes/installations with administrator rights but somehow this goes against EweLink principles).
Please leave your vote and share your comment in my linked topic to refresh the topic and renew our request. Thank You.
