Currently i use automations in HA and some via nodered.
But it would really nice (especially for beginners with HA) if we can create and edit automations with some kind of flow diagram. Another home automation platform has this kind of flow diagram built in, which is looking really really nice (and easy to understand).
Above images and video are for inspiration only i guess
I guess this will be a hell of a job to develop, but i think it will be really easy for beginners to use this (discussed with some people and they are complaining about the ease of use of automations in HA, which is to tech-people-minded in their opinion).
HA knows all my sensors and data, for nodered i have to struggle to get the correct plugins / addons installed, working and updated.
Some inspiration: Advanced Flow (they have the standard and advanced flow).
This could even work with kind of blueprints
