Voice and remote control for any node-red flow

The technique developed for the 'tuyaTRIGGER' feature of the tuyaDAEMON project (an IOT framework), uses a Tuya switch as a dual port HW register.
Better, the switch is still usable as an IOT switch, only the countdown function is required.

A downsized implementation (3 nodes only) allows you to add remote control (from anywhere) and voice control to any node-red flow.

See here or in GitHub.

Hope that this gives you great ideas.
