I have created this fork to attempt to update it for newer homebridge version as well as understanding how the source code works.

homebridge-sunset-lamp-ble

Homebridge plugin for this specific sunset lamp, though in theory it should work with any "iStrip+" compatible lamp. This plugin has an encryption key that is hardcoded in the device so it likely will not work with other devices.

Installation and Configuration

Install with npm or the homebridge UI:

npm install homebridge-sunset-lamp-ble

Add an accessory and configure the name (anything you like!) and ble_address (of the lamp, must be in lowercase) like below:

{
    "accessory": "SunsetLamp",
    "name": "Sunset Lamp",
    "ble_address": "xx:xx:xx:xx:xx:xx"
},

If you need to find the address of your lamp, you can add an accessory with no ble_address and check your homebridge logs. It seems these particular lamps always advertise with a name in the format of SSL-DDEEFF where DDEEFF is the last 6 letters of the address.

For example, with the logs:

[11/6/2021, 7:29:29 AM] [Sunset Lamp] Discovered:  SSL-DDEEFF  (aa:bb:cc:dd:ee:ff)

You can set the ble_address to:

...
    "ble_address": "aa:bb:cc:dd:ee:ff"
...

Limitations

• The lamps can only handle one connection at a time and do not automatically disconnect so you may have to turn the lamp on/off to get it to initially connect in Homebridge. I recommend installing and testing noble separately too before trying this plugin.
• The lamp does not provide any information of it's current state (or at least the "iStrip+" app I reverse engineered does not implement this) - it will always default to being off in homebridge when starting even if the lamp is already on.

Credit

This is essentially a fork of homebridge-led-strip-ble modified to work with the encryption in place on this lamp, so huge credit to stoner221 for the homebridge integration.
