@smarthome.exchange/interfaces

📐 Shared TypeScript data interfaces and TypedRequest contracts for every smarthome.exchange package.

This package is the contract layer. It defines the durable shapes for homes, devices, rooms, agents, automations, tools, approvals, audit receipts, dashboards, and typed hub requests. It contains no runtime business logic, which makes it safe to import from hubs, CLIs, browser apps, automation files, tests, and integration packages.

Import Pattern

import type { data, request } from '@smarthome.exchange/interfaces';

const device: data.IDeviceDefinition = {
  id: 'light.living.floor',
  name: 'Living Floor Lamp',
  protocol: 'hue',
  online: true,
  features: [
    {
      id: 'power',
      capability: 'light',
      name: 'Power',
      readable: true,
      writable: true,
    },
  ],
  state: [
    {
      featureId: 'power',
      value: true,
      updatedAt: new Date().toISOString(),
    },
  ],
};

type SnapshotResponse = request.IReq_GetHomeSnapshot['response'];

Public Surface

The package exports two namespaces from the root entry point:

Namespace	What it contains
`data`	Durable domain objects such as `IDeviceDefinition`, `IAgentDefinition`, `IToolPlan`, `IApprovalRequest`, and `IHomeSnapshot`.
`request`	TypedRequest contracts such as `IReq_ListDevices`, `IReq_ExecuteToolPlan`, and `IReq_SubmitApproval`.

Data Contracts

Core groups include:

Home state: IHomeDefinition, IHomeMember, IHomeSnapshot.
Devices and rooms: IDeviceDefinition, IDeviceFeature, IDeviceState, IRoomDefinition.
Agents: IAgentDefinition, IAgentStatus, IAgentReasoningEvent.
Tools and approvals: IToolDefinition, IToolCall, IToolPlan, IToolPlanResult, IApprovalRequest.
Automations: IAutomationDefinition, IAutomationTrigger, IAutomationRun.
Dashboards and audit: IDashboardDefinition, IDashboardWidget, IAuditReceipt.

Device protocols are explicit string unions such as matter, zigbee, thread, mqtt, homeassistant, hue, http, cloud, and virtual. Tool scopes are equally explicit, including device.read, device.write, light.write, climate.write, approval.write, and *.read.

TypedRequest Contracts

The request namespace defines the hub API boundary:

Method	Contract	Purpose
`getHomeSnapshot`	`IReq_GetHomeSnapshot`	Return the complete home snapshot.
`listDevices`	`IReq_ListDevices`	List devices, optionally filtered by room/capability/online state.
`listAgents`	`IReq_ListAgents`	List agents and runtime statuses.
`listTools`	`IReq_ListTools`	List available tools, optionally by owner.
`executeToolPlan`	`IReq_ExecuteToolPlan`	Execute, queue, or suggest a typed tool plan.
`listApprovals`	`IReq_ListApprovals`	Query approval requests by status.
`submitApproval`	`IReq_SubmitApproval`	Approve or reject a pending approval.

Every request interface carries a literal method, a typed request, and a typed response, so API clients and hub handlers stay in lockstep.
