IOT Platform with Pub Sub?

Hi there.

What I currently have with Google Cloud is that when a Device turns on or off it writes its state to a database collection, when an user updates another database collection a Cloud Function gets triggered which sends a command to the Device which then updates its state again to reflect the change.

I've looked at Mainflux but they also handle User Authentication and since I want this to get written to a Database it's kind of confusing.

Is there any Open Source or at least self-hostable IoT Platform that supports something similar?

My apologies if not everything is clear, I can elaborate.

Thanks.

Charging/leaving a phone outside

I'm wanting to build a simple device that will require leaving a phone outside (hopefully semi-permanently), is solar a good solution for keeping it charged so I don't have to constantly be changing out power banks? If not what are your recommendations?
