It probably isn’t, otherwise all neat HA integrations were available as Homey app already 
My ‘solution’ (best of both!): buy a (old) Rpi, or NUC / thin client (with Ble of course), install HA, add the devices you like, and connect them with Homey as they were native Homey devices, by means of the neat Home Assistant Community app.
My 2nd NUC was €40,-, just to give you the idea
