Doover App Explorer

This skill helps you search and explore existing Doover applications to evaluate functionality, find apps for integration, and understand available components.

Important Note

The App Explorer and public API only show public and Doover core apps. Your organization may have access to additional private apps that are not listed here. Private apps are shared directly between organizations and won’t appear in public searches.

To see all apps available to you, check your organization’s app library in the Doover admin panel.

App Explorer UI

Browse available apps visually at:

https://admin.doover.com/app-explorer

The web interface provides:

• Searchable list of all public applications
• App details including description and configuration
• Dependency visualization
• Installation statistics

API Access

Query apps programmatically using the public API:

GET https://api.doover.com/public/applications/

Pagination

Example Request

curl "https://api.doover.com/public/applications/?page=1&per_page=100"

Application Fields

App Types

Doover has three types of applications:

Device Apps (DEV)

Run as Docker containers on field devices. They:

• Access hardware via platform interface (GPIO, Modbus)
• Run continuously with a main loop
• Provide real-time device UI

Processors (PRO)

Cloud-based apps triggered by:

• Channel messages (react to device data)
• Schedules (periodic tasks)

Installed per-device, can update device UI remotely.

Integrations (INT)

Cloud-based apps that:

• Receive HTTP POST from external systems
• Are installed at the organization level
• Forward data to device channels

See the doover-cloud-apps skill for detailed documentation on processors and integrations.

Visibility Levels

Note: Private apps (PRI) are not visible in the public API or App Explorer. They are shared directly between organizations and only accessible to authorized users.

Core System Apps

These are foundational apps that other apps depend on:

Platform Interface

• Purpose: Hardware I/O access (digital/analog inputs and outputs)
• Provides: gRPC interface for GPIO, pulse counting, scheduled outputs
• Used by: Apps needing hardware control

Device Agent

• Purpose: Cloud connectivity and data management
• Provides: Channel publishing, tag management, remote configuration
• Used by: All apps needing cloud features

Modbus Interface

• Purpose: Modbus RTU/TCP communication
• Provides: Register read/write, polling subscriptions, virtual servers
• Used by: Apps communicating with Modbus devices

Finding Apps for Integration

By Functionality

Search the API or UI for apps by their purpose:

# Fetch all apps and filter locally
curl "https://api.doover.com/public/applications/?per_page=100" | \
  jq '.results[] | select(.description | test("modbus"; "i"))'

By Dependencies

Find apps that depend on a specific app:

import requests

response = requests.get("https://api.doover.com/public/applications/?per_page=100")
apps = response.json()["results"]

# Find apps depending on platform_interface
platform_id = "93956442461108741"
dependent_apps = [
    app for app in apps
    if platform_id in app.get("depends_on", [])
]

By Config Schema

Examine config schemas to understand integration points:

# Find apps that accept application references
apps_with_app_refs = [
    app for app in apps
    if "doover-application" in str(app.get("config_schema", {}))
]

Understanding Config Schemas

Config schemas use JSON Schema with Doover extensions:

Standard Properties

{
  "config_schema": {
    "$schema": "https://json-schema.org/draft/2020-12/schema",
    "type": "object",
    "properties": {
      "pump_pin": {
        "title": "Pump Output Pin",
        "type": "integer",
        "default": 0,
        "minimum": 0,
        "maximum": 31
      }
    },
    "required": ["pump_pin"]
  }
}

Doover Extensions

Application References

Apps can reference other apps in their config:

{
  "data_logger_app": {
    "title": "Data Logger Application",
    "type": "string",
    "format": "doover-application",
    "description": "App key of the data logger to send data to"
  }
}

Example Apps

Small Motor Control

Controls engine ignition, starter, and emergency stop:

• Dependencies: Platform Interface
• Tags exposed: state, run_request_reason
• Config: Pin assignments for starter, ignition, run sense

{
  "name": "small_motor_control",
  "display_name": "Small Motor Control",
  "depends_on": ["93956442461108741"],
  "config_schema": {
    "properties": {
      "starter_pin": { "type": "integer" },
      "ignition_pin": { "type": "integer" },
      "run_sense_pins": { "type": "array" }
    }
  }
}

Modbus Channel Relay

Bridges Modbus devices to Doover channels:

• Dependencies: Modbus Interface, Device Agent
• Purpose: Read Modbus registers and publish as JSON to channels
• Config: Register mappings, data types, channel names

Generator Control

Complex state machine for generator management:

• Dependencies: Platform Interface, Small Motor Control
• Features: Auto start/stop, warmup/cooldown cycles, scheduling
• States: off, starting, warmup, running, cooldown, stopping, error

Integrating with Existing Apps

Reading Tags from Other Apps

class MyApp(Application):
    async def main_loop(self):
        # Get app key from config
        motor_app_key = self.config.motor_control_app.value

        # Read state from motor control app
        motor_state = self.get_tag("state", app_key=motor_app_key)
        run_reason = self.get_tag("run_request_reason", app_key=motor_app_key)

        if motor_state == "running":
            await self.process_motor_running()

Coordinating with Other Apps

class CoordinatorApp(Application):
    async def main_loop(self):
        # Read status from multiple apps
        apps = [a.value for a in self.config.managed_apps.elements]

        statuses = {}
        for app_key in apps:
            statuses[app_key] = self.get_tag("status", app_key=app_key)

        # Coordinate based on aggregate status
        all_ready = all(s == "ready" for s in statuses.values())
        if all_ready:
            await self.start_sequence()

Config for App References

from pydoover.config import Schema, Application

class MyConfig(Schema):
    def __init__(self):
        self.motor_control_app = Application(
            "Motor Control App",
            description="App key of the motor control instance"
        )

        self.data_logger_app = Application(
            "Data Logger App",
            description="App key for data logging"
        )

Evaluating Apps

When evaluating an app for use:

1. Check dependencies – Ensure required apps are available
2. Review config schema – Understand required configuration
3. Read long_description – Full documentation and usage notes
4. Check allow_many – Whether multiple instances are supported
5. Review tags exposed – What data the app publishes
6. Check install count – Indicator of maturity/reliability

Searching Tips

Find Hardware Control Apps

Look for apps depending on Platform Interface:

curl -s "https://api.doover.com/public/applications/?per_page=100" | \
  jq '[.results[] | select(.depends_on | index("93956442461108741"))] |
      .[] | {name, display_name, description}'

Find Protocol Bridges

Search for “modbus”, “mqtt”, “relay”, “bridge” in descriptions:

curl -s "https://api.doover.com/public/applications/?per_page=100" | \
  jq '.results[] | select(.description | test("modbus|mqtt|bridge"; "i")) |
      {name, display_name, description}'

Find Apps with Specific Config Types

# Apps accepting schedule configuration
curl -s "https://api.doover.com/public/applications/?per_page=100" | \
  jq '.results[] | select(.config_schema | tostring | test("doover-schedule")) |
      {name, display_name}'

Using App Explorer in Development

Before Building a New App

1. Search the explorer for existing functionality
2. Check if an existing app can be extended or configured
3. Look for apps with similar dependencies for patterns
4. Review config schemas for integration approaches

When Integrating Apps

1. Find the target app’s ID and exposed tags
2. Add application reference to your config schema
3. Use get_tag() with the app key to read data
4. Coordinate via tags or channels

Understanding the Ecosystem

The app explorer helps you understand:

• What infrastructure apps are available
• Common patterns in config schemas
• How apps depend on each other
• What functionality already exists
