Can Alexa be connected to two HA?

Tags: #<Tag:0x00007f77fce6f7f0>

“Small” issue here.
I have my main HA account with Nabu casa and Alexa integration on a Rasp 3b+. Works perfectly.
I have a second HA on a desktop used for camera feeds and recording. As this is powerfull unit and its connected 24/7 I installed plex on it. Only after everything is done I realize that I cannot use my echo to access the musics as it is not “installed” there.
So, I don’t want to subscribe another nabucasa, and I’m not even sure alexa would handle 2 accounts.
Maybe I can try to integrate it manually.
Does anyone knows if it would work, or have any alternative?
