Switchboard

IoT research Engineering collaborator

Tuya Smart API integration for custom hardware control — cloud commands mapped to local relays, sensors, and operator workflows.

Problem

Off-the-shelf smart plugs rarely match custom hardware timelines. Switchboard experiments with Tuya Smart API bridges so bespoke firmware can subscribe to cloud commands while exposing local sensor state back to automations.

What it covers

Tuya device registration and command dispatch wrappers
Mapping cloud DP IDs to local GPIO/actuator handlers
Heartbeat and state publish loop for automations
Embedded hooks for custom sensor ingestion

Cloud to device command

type DeviceHandler = (value: unknown) => Promise<void>;

const dpHandlers: Record<string, DeviceHandler> = {
  switch_1: async (on) => relay.set(Boolean(on)),
  temp_current: async (c) => telemetry.publish('temp', Number(c)),
};

export async function onDpUpdate(id: string, value: unknown) {
  await dpHandlers[id]?.(value);
}
