Hello, i am a newbie in creating a smart home. I have researched a bit and planned the following stack just by reading and hopefully to get some suggestion to see if the following combinations would actually work

Goal

I am planning the main control to be Home Assistant, Homekit a nice to have, not necessary. I was looking at hubs (Aqara, Xiaomi, Ikea, Homepod) but a comment from r/aqara suggests that ComBee II is potentially a better solution

Components that i think might work

• Home Assistant + ComBee II: as the brain power
• Light bulbs: ikea rgb and aqara white/cream colour
• sensor: aqara
• curtain driver: aqara
• smart socket/plug: ikea and aqara

Components not sure how to integrate

• Mijia sensors + display: This is a bluetooth device that works as sensor but i am just going display those information it catches
• Aqara door bell: not sure if this is a zigbee 3 device or not
• Other bluetooth device
• Xiaomi vacuum: not sure what protocol but isn’t the biggest matter
• Unsure which brand is good for security cams

questions

• Any idea if the above makes sense in practice?
• Any experience on the few items that I wasn’t sure of?
