Migrating from coco /kaku ics 2000 to homey: how complex?

hi there, i currently use the ics2000 as my main hub to control a mixture of coco/kaku built-in switched , lifx lamps, innr zigbee bulbs, somfy blinds… all integrated with alexa.
i tried to replace the whole thing with smartthings, but did not see the benefit since i still needed to keep the ics to control the built-in coco/kaku awmd-250 dimmers.
so i stopped using smartthings (i l don’t have any z-wave products)

i am wondering whether replacing everything my hub with homey will:

  • provide me with a nice interface than the (crap) kaku/trust one
  • make the integration faster and response time faster (alexa takes its time to turn off the lights)
    and most importantly, i would like to know if i need to reinstall everything in order to migrate from my current setup. (ie, do i need to put everything back in discovery mode??)

i currently have integrated and functionning:
2 kaku light bulbs
4 kaku awmd-250 dimmers
1 kaku blind controller
1 somfy blind controller (zigbee)
4 innr gu10 zigbee lamps
2 innr zigbee lamps
4 lifx bulbs
1 kaku wall switch
fibaro dimmer bypass (various)
ring pro
alexa (various)
samsung tv
harmony remote
various kaku wall switches and remotes

can someone help me justify my purchase?

Yes you need to include your device to homey, cant just replace the ics2000 with homey and think it all would magicly work with homey.
