Architecture

Hub configuration

Hub must be configured, by default it's placed in $XDG_CONFIG_HOME/houseflow/hub.toml.

Example configuration

# Houseflow hub configuration

[hub]
# UUID of the Hub, generate using `uuidgen` command
id = "00000000-0000-0000-0000-000000000000"

# Uncomment to allow outside network accesss
# [network]
# address = "0.0.0.0"

[[accessories]]
id = "1c59f25a-a5b4-4248-810f-01422cee16b0"
name = "super termometr"
room-name = "Bedroom"
manufacturer = "xiaomi-mijia"
model = "hygro-thermometer"
mac-address = "A4:C1:38:EF:77:51"

[providers.mijia]

[controllers.hap]
pin = "11122333"
name = "ExampleHub"

[controllers.meta]

Controllers

Controllers control the accessories from the outside.

HomeKit Accessory Protocol

Allows you to integrate Apple Home app with Houseflow Hub.

Example configuration:

[controllers.hap]
# The `Pin` struct represents the server's 8 digit pin used for pairing.
#
# The pin consists of eight digits between 0 and 9 and defaults to `11122333`.
#
# The following pins are considered too easy and are therefore not allowed:
# - `00000000`
# - `11111111`
# - `22222222`
# - `33333333`
# - `44444444`
# - `55555555`
# - `66666666`
# - `77777777`
# - `88888888`
# - `99999999`
# - `12345678`
# - `87654321`
pin = "11122333"
# Name of the Hub. The name will be visible in the Apple Home app
name = "ExampleHub"

To clear caches, remove ~/.local/share/houseflow/hap/ folder.

Meta HTTP API

Provides HTTP API for Houseflow Hub communication. Check Meta HTTP API Scheme for more details.

Remember to add /controllers/meta/ in the URL Path before. For example

GET houseflow_hub.local:5001/controller/meta/characteristic/00000000-0000-0000-0000-000000000000/temperature-sensor/current-temperature

Example configuration:

[controllers.metea]

Providers

Providers provide accessories for the hub.

Mijia

Allows Xiaomi Mijia devices to connect

Example configuration:

[providers.mijia]

Meta HTTP API Scheme

Read characteristic

Request

GET /characteristic/:accessory-id/:service-name/:characteristic-name

Response

{
    "name": :characteristc_name
    // ... values of the characteristic
}

Example

Reading characteristic with following params:

accessory-id: 00000000-0000-0000-0000-000000000000
service-name: temperature-sensor
characteristic-name: current-temperature

GET /characteristic/00000000-0000-0000-0000-000000000000/temperature-sensor/current-temperature

And if the accessory is connected, and implements the service with the characteristic, it should return

{
    "name": "current-temperature",
    "temperature": 21.89 // or whatever the current temperature is
}

Write characteristic

Request

POST /characteristic/:accessory-id/:service-name
Content-Type: application/json
{
    "name": :characteristic-name,
    // ... values of the characteristic
}

Response

If status is OK, then it returns empty body, otherwise it returns error message in JSON format.

Example

Reading characteristic with following params:

accessory-id: 00000000-0000-0000-0000-000000000000
service-name: garage-door-opener
characteristic.name: target-door-state
characteristic.open-percent: 80

POST /characteristic/00000000-0000-0000-0000-000000000000/garage-door-opener
{
    "name": "target-door-state",
    "open-percent": 80 // or whatever the current temperature is
}
