Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Control Soma BTLE Smart Shade devices by HTTP or MQTT

Readme

SOMA Blind Controller Util npm version

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

Requirements

  • 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 8.16.1 or higher (Tested on Node 12.10.0, 11.15.0, 10.15.2, 9.11.2, 8.16.1)
  • (Potentially a Bluetooth stick to itself, if you're using some other Bluetooth software, see #59)

Installation

Run npm install -g soma-ctrl

Usage

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

To use with HTTP

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

To use with MQTT

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

MQTT

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",
    "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"
    }
}

Parameters

<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
