#How to make Alexa and Siri working simultaneously?

I’m setting up smart home automations and ran into a limitation that I can’t quite figure out.

I recently bought some smart switches that support Matter. However, when I try to set them up, they only seem to connect to either Apple HomeKit or Alexa — not both at the same time.

Here’s my setup:

  • I use Apple devices (iPhone, iPad, Apple TV)

  • I don’t have a HomePod

  • I also use Alexa as part of my smart home

  • I run (or plan to run) Home Assistant

Important context:

A HomePod is not an option for me. Apple doesn’t officially sell it in my country, it’s not supported in my native language, and my family doesn’t speak English — so even if I imported one, it wouldn’t be usable for us.

From what I understand, Matter devices should support multi-admin (being connected to multiple ecosystems), but in practice I haven’t been able to get that working — once I pair the device with one ecosystem, I can’t seem to add it to the other.

So I’m considering buying a Raspberry Pi 4 to run something like HomeBridge or Home Assistant to act as a bridge between ecosystems.

My questions:

  1. ⁠Can HomeAssistant allow me to expose the same devices to both HomeKit and Alexa at the same time?
  2. ⁠Is HomeBridge a better option for this use case?
  3. ⁠Is there a way to properly use Matter multi-admin so I don’t need a workaround?
  4. ⁠Is Apple TV alone enough as a HomeKit hub for this to work reliably?

Basically, I want my devices (Matter or not) to be usable simultaneously in both Apple Home and Alexa ecosystems.

Any advice or recommended setup would be really appreciated!
