Not sure if @Lgkahn updated his version of the DTH but to get things working in the new app, I added vid: “generic-contact-4”, ocfdevicetype: “oic.d.garagedoor” to the metasdata sometime ago and it is still working. It’s not as asthetically pleasing as the classic app tiles but it works.
There is more discussion here and a screenshot of what it looks like in the new app.
