Remember when we had to run a new 4-conductor for every single keypad?

I was retrofitting a 1970s split-level in Boise and the thought of fishing that many new wires made me groan. On a whim, I tried using the existing doorbell wire as a data loop for a modern wireless translator module. It worked perfectly for the upstairs zone. What's the oldest wiring you've successfully repurposed for a smart system?

That doorbell wire trick is clever. What specific wireless translator module did you use for that setup? I'm curious about the data speed it could handle over such old copper.

Yeah, that old copper can be a real pain. Makes you wonder what the actual limit is, right?
