Initial excitement tempered once I realised this is just a single automation for now, but nevertheless a very nice feature release!
I have a moderate complexity combo of 4 scripts, 4 automations, 4 input_booleans and one timer, to control an MVHR system over modbus. initially thought maybe i could make a blueprint of that to support my second MVHR unit, but I guess i’ll have to copy and paste, search and replace for the time being 
Would be great in future if blueprints could include templated versions of various things (eg scripts, timers) as well, along with a suggested lovelace card setup.
