Good idea, thanks!
I was hoping for a root cause and solution but it doesn't really matter, so long as it's working. Threw this into a 10 second repeat and now it's working fine.

I've tethered my Omega2 to a roving hotspot: usually it's available but sometimes it won't be (typically overnight, up to 16 hours).
It connects just fine on boot if the hotspot is available, and if it's gone for only a few minutes and then comes back it has no problem reconnecting.
But if it boots up while the hotspot is unavailable, or if it goes away for several hours, then it simply never reconnects automatically when it returns. I have to run wifimanager to force it to reconnect.
Any thoughts on why this might be and how to fix it?

I have a plan to connect a 5v solar panel to my power dock with the intention of charging the battery during the day so it can continue to run at night. With a large enough panel and a 3000mah battery this shouldn't be any problem, but before I go spending a few dozen dollars on what I need I want to make sure the power dock itself can do this.
How does it behave when the charging amps drop below the usage amps? As the sun goes down, will it automatically start siphoning off the battery? Or will I need to implement a cut-off switch to completely break the line when it can't keep up with the need? I'm reasonably certain it's the former but hoping someone can confirm.
Thanks!
