I've been looking every now and then over the past several days. I still haven't found anything. Will try the tar file, but I'd rather have a repo that can automatically update me whenever necessary.
Somehow the platform info disappeared. I'm looking for the Raspberry Pi armv7 .deb or repo.
I'm uncertain what you're looking for. The downloads of TeamViewer Host for Raspberry Pi are on the download page: https://www.teamviewer.com/en/download/linux/
If you already have TeamViewer Host (DEB/RPM) installed on your Pi, you can just update it like every other package, e.g.
apt install teamviewer-host
