Very new to Arduino. Currently waiting for my first ones to arrive, but I have a longer-term project idea that I'd like to get feasibility for.
Essentially, my idea is to have a local webserver (only serving to the local network) with custom, hand-built pages that are pretty basic. This would serve what will essentially be a control system for my smart-home and other bits in the flat. I'd like to be able to have some screens peppered around my flat, controlled by Arduinos, that serve this page and can be interacted with using buttons. I'm not going to attempt to make a general web browser, it would just be for these highly simplified pages (static HTML for one thing).
Before I get too deep into this project, I want to know whether it's even feasible and if it is, what sort of power it's going to need. I'm under no illusions about it being a lot of work - the technical challenge is half the point! The main constraint is that it needs to be battery-powered, although I am willing to get rechargeables or use power banks.
