    0.4.1 • Public • Published

    Builds off of https://github.com/renssies/homebridge-am43-blinds but in typescript instead, with some additional features, but (due to BLE differences between plaforms) it'll likely only work on Raspberry Pi (/ other linux) based homebridge instances.

    Homebridge AM43 Blinds

    A homebridge plugin to control the AM43 based blind motors in HomeKit, these include the A-OK, Zemismart, Upndown and other blinds motors that use Bluetooth and the Blinds Engine app.

    This Homebridge plugin uses the Bluetooth on your homebridge device to search for, and connect to the AM43 blinds via the "Blind Engine" part of the Settings in homebridge-config-ui.

    Known Issues

    • Bluez sometimes fails on startup causing homebridge to enter a restart loop. Requires rebooting the device to fix. This used to cause the devices to be dropped from HomeKit, but I've moved when they're initialised to before the BLE connection to prevent this.
    • node-ble doesn't support limiting discovered devices by a service UUID, I've created my Own Fork to handle this - it definately limits the results, but I'm not sure if it only seems to work because the blinds are already connected. It's entirely possible that it won't connect to anything for anyone else.
    • Siri can still sometimes say "Device is not responding" even after the device is doing what you asked. Not sure why this happens, the connection is fast & reliable.
    • Blind will report that a name change was successful but then not actually change the BLE name. ( Any user level naming should be done in the config prior to adding the blind or in HomeKit itself )
    • While in the Blind Engine UI there can be 2 toast notification for each action, this doesn't seem to cause any errors so should be fine.

    Requirements

    This plugin requires Node version 14 or newer and Homebridge version 1.3.0 or newer. It must be run on a linux system with bluez (e.g. a Raspberry PI).

    Installation

    Before installing set up node-ble by creating the following file in /etc/dbus-1/system.d/node-ble.conf (assuming that your homebridge instance is run as homebridge)

    <!DOCTYPE busconfig PUBLIC "-//freedesktop//DTD D-BUS Bus Configuration 1.0//EN"
      "http://www.freedesktop.org/standards/dbus/1.0/busconfig.dtd">
    <busconfig>
      <policy user="homebridge">
       <allow own="org.bluez"/>
        <allow send_destination="org.bluez"/>
        <allow send_interface="org.bluez.GattCharacteristic1"/>
        <allow send_interface="org.bluez.GattDescriptor1"/>
        <allow send_interface="org.freedesktop.DBus.ObjectManager"/>
        <allow send_interface="org.freedesktop.DBus.Properties"/>
      </policy>
    </busconfig>

    See the node-ble docs for more information

    Debugging

    Running homebridge with DEBUG=AM43 should cause motor-level debug logs to be output.

    So to run homebridge in debug mode use the command DEBUG=AM43 homebridge -D to log debug messages of the AM43 plugin. Or DEBUG=* homebridge -D to log messages of all plugins.

    The logs can be found in ~/.homebridge or any custom folder you've specified. They should also be available in the Homebridge Config UI (if homebridge-config-ui-x is installed)

    Install

    npm i homebridge-am43-blinds-bluez
