Remote Relay (Rust)

Originally coded in Python, Remote Relay is an http server interface that allows a user to control their in home smartplugs (and other forms of relays with a boolean state) externally from the respective smartplug's ecosystem.

Getting Started

Only Rust is required to build and run from source.

cargo build --release
cargo run --color=always

Config and Config Options

Currently, you can set your configuration via local file in config.json or through a MongoDB database through a .env file. Application defaults to local config.

Local Configuration

All local configuration is stored in config.json at root level of project directory.

An example configuration will look like this:

{
  "relays": [
    // TPLink Kasa Plug example relay configuration
    {
      "type": "KasaPlug",                                   // Type of relay, case-sensitive, required for configuration loader to differentiate
      "name": "Sample Name",                                // Name of relay, use normal string restrictions
      "ip": "<ip address of relay>",                        // IPv4 address of relay. Can get this from router devices
      "room": "bedroom"                                     // Optional room location of relay
    },
    {
      "type": "KasaMultiPlug",                              // Type of relay, case-sensitive, required for configuration loader to differentiate
      "names": ["Sample Name 1", "Sample Name 2"],          // Names of relays, length must match exactly with number of relays on device
      "ip": "<ip address of relay>",                        // IPv4 address of relay. Can get this from router devices
      "room": "bedroom"                                     // Optional room location of relay
    }
  ],
  "presets": [
    {
      "name": "Bedroom on",       // Name of relay, use normal string restrictions
      "enabled": true,            // For UI use, keeps the ability to store many different configurations without sending them all to a frontend
      "relays": {                     
        "Sample Name": true
      }
    }
  ]
}

As of this current version, by default presets will turn off every relay not explicitly stated to be turned on (set to true) in the preset config. Future efforts will be made toward an explicit boolean option per presets to let the user define if they want that preset to explicitly control all relays on preset toggle.

Mongo Configuration

To set up a configuration through a Mongo Database, the following must be exact:

1. Your .env file must contain the connection string denoted by a MONGODB_URL= variable, placed at root level of running directory.
2. All collections must be in a database named HomeConfig
3. Relays and Presets (case-sensitive) collections must be present in HomeConfig
4. Relays and Presets are formatted just like in local config, with each relay/preset being its own document

For a visual representation:

• HomeConfig (Database)
  • Relays (Collection)
  • Presets (Collection)

Routes

Index Routes

Route	Description
/	Health Check
/status	Gets full status of all relays
/refresh	Endpoint for refreshing config, useful for dynamic config loading testing and external debugging

Preset Routes

Route	Description
/preset/getPresetNames	Gets list of all preset names
/preset/setPreset/<preset_name>	Sets preset via name

Relay Routes

Route	Description
/relay/<relay_name>/set/	Gives command to specific relay. Commands include ON, OFF, SWITCH, and STATUS
