With the help of Blockly or Node Red it would be mega if there where a component to control:
LEGO Boost
LEGO Mindstorm

Are there any custom components for HA?
I know this is old, but replying here for anyone else that runs across this… A Node-red move hub component can be found here: node-red-contrib-movehub (node) - Node-RED
Have not been able to get my Bluetooth working in HA yet to try this myself, but looks promising…
