Util for controlling SOMA smart shade, either over MQTT or via a HTTP API

• SOMA smart shade device that has been configured with the SOMA app
• Bluetooth 4.0 LE hardware
• OS supported by noble (I've only tested on macOS and Raspbian)
• Node 7.0 to 9.x (noble currently has issues with 10.x and up)
• (Potentially a Bluetooth stick to itself, if you're using some other Bluetooth software, see #59)

Run npm install -g soma-ctrl

somactrl by itself will print usage information

By default, device scanning will be active for 30 seconds, and any supported ones will be connected to. You may optionally:

• Alter the device scanning timeout, e.g. scan for 60 seconds: somactrl -t 60
• Specify the number of devices you expect to connect to, e.g. 4 devices expected: somactrl -e 4
• Manually specify a list of device IDs to connect to, e.g. connect to RISE108 and RISE117: somactrl RISE108 RISE117
• Manually specify a list of MAC addresses to connect to, e.g.: somactrl f5:11:7b:ee:f3:43

You must then specify options to use either MQTT, HTTP or both

Specify a port for the API to listen on with -l: somactrl -l 3000

Specify a broker URL with --url option: somactrl --url mqtt://yourbroker (mqtt/mqtts/ws/wss accepted)

Username and password for MQTT may be specified with -u and -p option

If no password argument is supplied, you can enter it interactively

Base topic defaults to homeassistant, but may be configured with the -topic option

For each device connected, data will be published to the following topics: <baseTopic>/cover/<deviceID>/position - position

<baseTopic>/cover/<deviceID>/connected - connected or disconnected

<baseTopic>/cover/<deviceID>/battery - battery level

To issue commands: Move: <baseTopic>/cover/<deviceID>/move - message: int position between 0 (closed) and 100 (open)

Stop: <baseTopic>/cover/<deviceID>/move - message: 'stop'

Identify (beep device): <baseTopic>/cover/<deviceID/identify - message is ignored

In addition, for use with Home Assistant MQTT Discovery:

To automatically setup the cover device: <baseTopic>/cover/<deviceID>/config will be set to, e.g.:

{
    "name": "Living Room1",
    "state_topic": "homeassistant/cover/RISE148/position",
    "availability_topic": "homeassistant/cover/RISE148/connection",
    "payload_available": "connected",
    "payload_not_available": "disconnected",
    "position_topic": "homeassistant/cover/RISE148/position",
    "set_position_topic": "homeassistant/cover/RISE148/move",
    "command_topic": "homeassistant/cover/RISE148/move",
    "payload_open": "100",
    "payload_close": "0",
    "unique_id": "soma_RISE148_cover",
    "device": {
        "identifiers": "soma_RISE148",
        "name": "RISE148",
        "manufacturer": "Soma",
        "model": "Smart Shade"
    }
}

To automatically setup a battery sensor: <baseTopic>/sensor/cover_<deviceName|slugified>_battery/config will be set to, e.g.:

{
    "name": "Cover <deviceID> battery",
    "state_topic": "<baseTopic>/cover/<deviceID>/battery",
    "unit_of_measurement": "%",
    "device_class": "battery",
    "unique_id": "soma_<deviceID>_battery",
    "device": {
        "identifiers": "soma_RISE148",
        "name": "RISE148",
        "manufacturer": "Soma",
        "model": "Smart Shade"
    }
}

<deviceID> has format RISEnnn or the device's MAC address in lowercase, with the colon's stripped out and cannot be changed

<deviceName|slugified> will be the device name (as configured in the app) with spaces replaced by underscores

GET /: list devices. Response type: [String : Device] - ID as String key, Device as value

        "group": "Living Room",
        "name": "Living Room2"
    }
}

GET /<deviceID>: Get individual device data (or 404 if no device by that ID).
