In Maryland at least, there are non-hard-wired alternatives in some cases that aren't new construction but still trigger an upgrade required.

I have some that have "long-term tamper-proof batteries" (I think they last 5 years or something)... and _somehow_ are "interconnected" (so they can all trigger each other) which was a requirement. They don't use _my_ wifi, I don't know how they are interconnected without wires exactly (or if it even really works). I'm not worried about it, but it passed inspection.
