How do you guys manage your phone farms remotely?

Hey everyone,
I currently manage all my phones manually in person, but I’ll be going on a trip soon and won’t be able to access them physically for a while. I'm looking for any tips, tools, or software that can help me manage everything remotely while I’m away.

Especially curious to hear from those of you running 100+ phones, how do you keep things running smoothly at that scale without being there in person?

Some specific things I’m wondering about:

How do you reboot / control devices remotely?

How do you handle phone updates, app crashes?

Any insights or recommendations would be really appreciated. Trying to set this up before I leave. Thanks in advance!
