Pros of Home Assistant

• More active community with frequent updates and contributions
• Extensive ecosystem of integrations and add-ons
• User-friendly web interface and mobile app

Cons of Home Assistant

• Steeper learning curve for advanced configurations
• Higher resource requirements, especially for larger setups

Code Comparison

Home Assistant (Python):

class Light(ToggleEntity):
    @property
    def is_on(self):
        return self._state

    def turn_on(self, **kwargs):
        self._state = True
        self.schedule_update_ha_state()

ioBroker (JavaScript):

createState('myLight', false, {
    name: 'My Light',
    type: 'boolean',
    role: 'switch'
});

on({id: 'myLight', change: 'ne'}, function (obj) {
    console.log('Light state changed to: ' + obj.state.val);
});

Home Assistant uses a class-based approach with built-in entity types, while ioBroker relies on state creation and event-driven programming. Home Assistant's code is more object-oriented and abstracted, whereas ioBroker's code is more procedural and direct.

Pros of Domoticz

• Lightweight and efficient, suitable for running on low-power devices
• Extensive support for various hardware and protocols out-of-the-box
• User-friendly web interface for easy configuration and management

Cons of Domoticz

• Less flexible plugin system compared to ioBroker
• Smaller community and fewer third-party integrations
• Limited built-in visualization and dashboard options

Code Comparison

Domoticz (C++):

void CWebServer::Cmd_AddHardware(WebEmSession & session, const request& req, Json::Value &root)
{
    if (session.rights != 2)
    {
        session.reply_status = reply::forbidden;
        return; //Only admin user allowed
    }
    // ... (additional code)
}

ioBroker (JavaScript):

function createStateObject(id, name, type, role) {
    adapter.setObjectNotExists(id, {
        type: 'state',
        common: {
            name: name,
            type: type,
            role: role,
            read: true,
            write: true
        },
        native: {}
    });
}

Both projects have different approaches to handling hardware and state management, reflecting their architectural differences. Domoticz uses C++ for core functionality, while ioBroker relies on JavaScript for its adapter system.

Pros of home-assistant-config

• More focused on home automation and smart home devices
• Extensive documentation and community support
• Highly customizable with a wide range of integrations

Cons of home-assistant-config

• Steeper learning curve for beginners
• Requires more manual configuration compared to ioBroker
• May have higher resource requirements for complex setups

Code Comparison

home-assistant-config:

automation:
  - alias: "Turn on lights when motion detected"
    trigger:
      platform: state
      entity_id: binary_sensor.motion_sensor
      to: 'on'
    action:
      service: light.turn_on
      entity_id: light.living_room

ioBroker:

on({id: 'hm-rpc.0.MEQ1234567.1.MOTION', change: 'ne'}, function (obj) {
    if (obj.state.val) {
        setState('hue.0.living_room.light', true);
    }
});

Both examples show how to trigger a light when motion is detected, but home-assistant-config uses YAML configuration, while ioBroker uses JavaScript for scripting.

Pros of Node-RED

• Visual programming approach with a flow-based interface
• Extensive library of pre-built nodes for various integrations
• Active community with a large number of contributed nodes

Cons of Node-RED

• Steeper learning curve for complex automation scenarios
• Less comprehensive out-of-the-box device support compared to ioBroker
• May require more manual configuration for certain integrations

Code Comparison

Node-RED flow example:

[
    {
        "id": "f6f2187d.f17ca8",
        "type": "inject",
        "z": "2795455.f76c0ca",
        "name": "",
        "topic": "",
        "payload": "",
        "payloadType": "date",
        "repeat": "",
        "crontab": "",
        "once": false,
        "onceDelay": 0.1,
        "x": 110,
        "y": 80,
        "wires": [["1b1f4e.6f0c9f2"]]
    }
]

ioBroker script example:

createState('mySwitch', false, {
    name: 'My Switch',
    type: 'boolean',
    role: 'switch'
});

on({id: 'mySwitch', change: 'any'}, function (obj) {
    console.log('Switch state changed to ' + obj.state.val);
});
