TRKeys — Configurator

Connect your TRKeys

Plug the board in over USB and close any serial monitor that has the port open. Then connect and pick the device's port — your settings load automatically.

Requires Chrome or Edge on desktop (Windows, macOS, Linux)

Wi-Fi networks

Add up to 4 — the board scans and joins whichever is in range (strongest wins), and re-picks if it drops

Label is a location name for each network (e.g. home, office). The board joins whichever is in range. Use {loc} in any message below to insert the connected network's label — e.g. {"habit":"1","loc":"{loc}"}.
