I can't put holes in my roof or exterior at my current residence, but a salvaged ridge mount from Starlink seems to be getting the job done. SenseCAP Solar Node P1-Pro no longer has to stare longingly out my office window. A bit janky perhaps, but bonus points for not falling off steep roof while getting it up there!
I'm not sure. I have found the alpha versions to be quite stable, so that's not a huge issue. But I wouldn't expect the 2.7 to be an alpha very much longer. It's already at 2.7.10.
I would think they'd have a beta for 2.7 coming out pretty soon, as they've probably got most of the major things worked out.
