I mean, good thought. But you couldn’t pay me enough to put this in my home. Former electrical engineer a lifetime ago, this is not safe. At all. A plastic, ungrounded box. You did a good job on the shrink-wrapping, you still have a lot of exposed connections. 15v2a isn’t that high, but still a short to ground or a Li-ion battery run off, you’re going to have a very bad day.
