Newbie! Best hardware stack for my current setup (Aqara, roller shutters, TRVs, Daikin, Solarman)

[leaden mulch]

Hi all, first post! 🙏
I'm falling in love with this community, and I am trying not to be flooded with the complexity that this new world also entails (:
I’m planning my Home Assistant build and would love hardware recommendations that will play nicely together.

Current

• Aqara T1 Led strip (2mt + 2 x 1mt extensions), not connected, because i have yet to buy a proper hub.

Willing to smartify:

• Roller shutters: i have 10+ windows equipped with motors, using ⬆/⬇️ buttons. Based on my very limited knowledge, Sonoff Mini-RBS seemed a good choice, but please feel free to advice better
• Heat pump Daikin Altherma, which came with a Wlan card, an Access Point, an I/O device and about 15 Daikin TRV. Have not installed yet, but i know they should be managed by the Onecta App, though I am not sure if HA has the capabilities to manage it?
• Solar: panels monitored via Solarman Smart, through a wifi dongle.

I want to buy the HA Green, but I am not sure about how many other hubs, bridges or whatnot i need to buy /:
For example, I don't understand if the T1 Led strip could work with just the HA Green (and the ZBT-1)?? Or do I have to buy the Aqara Hub?

thank u so much!

Generally speaking you can use any** (of the supported) coordinators for zigbee and zwave with mostly any devices that matches their protocol and follow device standards.
The vendor specific hubs may be of limited functionality towards devices of other vendors and may be more tricky to integrate into homeassistant. You usually do not want to buy those

thank you @peak pine !
I guessed that, but isn't it true the other way around as well? meaning, couldn't HA be more limited in some functionalities?
For instance, i've read that i need the Aqara app to perfectly set the strips + its extension (you have to set the total lenght through their app for the color mode to work in the extensions too). I tried to download the app and to connect to the strip. It also make me choose an Hub, but HA is not among those listed /:
so i don't really understand wether the HA Green is the device to rule them all, or if i still need to buy several ones

There may be additional non standard feature sets that aren't mapped out properly but that's more common on wifi gear where there is a non standard protocol to begin with.
HomeAssistant isn't a hub and the Green is merely a device that runs HomeAssistant similar to how it would run on any other computer.

You will however need additional gear to run zigbee or zwave (a coordinator) and depending on specifics some setup for it to do threads and matter communication. Later is also usually optional

😥 first days digging into it, and the complexity feels quite intimidating

[peak pine]

Don't worry, it's much less difficult than it may sound

[leaden mulch]

may i ask u what would u do if you had to set it up from 0?

Depends on which way you want to go with it. You can start from figuring out your needs either from the devices you already own or the devices you want to buy

The device to run homeassistant on matters not a lot. You can get a green, a yellow, a raspberry pi or any other computer and then add capabilities to it as you may need. The only difference to pick from is wether you'd need additional compute for things like local voice models or surveillance cameras

Beyond that it's just a choice of which devices you want to control and the protocols they use

You can browse available integrations to check if it works mostly out of the box or which dependencies exist for them
