Works fine for me, it falls to the next-lowest priority when no signal is detected.

Maybe that's the problem... It's not a no signal. It's a non controlled shutdown... For example power shut... Maybe some tear down missing or something like that. Or and more probably since I have minisatip 0/1/2 and have the 0 With tuners with higher priority something like 7 8 9 10... When I disconnect and suppose it's working on 10 it tries 9 them 8 them 7 them 10 again.... And never pass to the minisatip 1 or 2 tuners

Provide --trace satip
