Hi All,

[night vessel]

New to HA, been researching! I would like to know if I got things right. I want to start-off small, so I am deciding to buy the "HA Green".

I want to start off with a robo-vacuum. From what I read, HA Green can connect with the vacuum over Wi-Fi, so that I dont need any additional tools (Like skynet etc)

For the future, I would like to know if I need to buy any of these for the future (Eventually I would have bulbs, window shades etc)

Hey there.
Home Assistant Green is a great way to start. It is plug n play and nice to get a taste.
Some people may refer it is lacking power (which if you need to run many integrations and some more processing is true) but in my experience all people I know starting loved it and worked great.

Watch out to confirm about robot vacuum compatibility. Most should be but check your model and do a search online. You may need to install HACS for some custom integration.

The Zigbee and Zwave you show are adaptors required if the bulbs and window shades require that protocol.
They create a fully local mesh network that does not rely on WIFI.
In my view it is worth to stick with only one of those. There are plus and cons to each.
When I started in my country Zigbee was more easily available so personally I have only used that so far.

Cheers

Thanks for the response..

Currently I don't have a vacuum, so I will buy whatever is compatible with HA

Regarding zigbee/wave, I will do more research.. I read that devices like cameras uses zigbee, while light bulbs use zwave

Both Zigbee and Zwave have many common device types. You can have bulbs and sensors of either protocol.
Researching is the best way to know. There are many resources online and lists!
