How to manually Install and connect to HASS of Docker because different architdcture

So I am running HASS fully managed on a Libre board (RPI alternative, ARM64, installed debian, then fully managed HASS).

Want to install the eWelink integration as explained here eWeLink connect to Home Assistant - eWeLink.
BUT it doesn’t support arm64 says the error message.
Brave (or stupid) enough I built and installed it manually on the debian, as described here GitHub - CoolKit-Technologies/ha-addon and it works.

but it is not recognized in the HASS of course as it wasn’t installed form there.

Questions:

  1. What is the way “to do this right”?
  2. How to “connect” it to HASS so the devices are recognized inside HASS?

Thanks!

That’s not an integration, that’s an add-on.

Integrations connect HA to other services/software/hardware or provide services in HA.
Add-ons are other software, which you can potentially integrate with

You want something like SonoffLAN.

Thanks so much @tinkerer. this was super helpful. Appreciated.
