What I really need is a droid who speaks the binary language of moisture vaporators.

We have a protocol droid at home, it’s called curl.

Considering the important parts of that, aka the languages can be done by your phone sure. But it would at least have a minimal use. R2 d2 needs special attachments to serve drinks.

The cybertray, competitively priced at 4000$ and the reported risk of it breaking when wet is fairly minimal.
