Add support for Yeelight bulbs

[vkolotov]

[arosboro]

I had confirmed this python can control and set the color w/ pi3 https://github.com/fayep/bolt. Also there is a PDF that documents BLE profiles of the yeelink lights floating around.

[vkolotov]

Hi @arosboro, thanks for that. I'll be working on this once I've received a new bulb.

[vkolotov]

Hey @arosboro, I've got now a Yeelight bulb... but it looks like it does not support Bluetooth at all. They either sent me a wrong item or I ordered a wrong item.

Can you please point me where I can get a Bluetooth enabled Yeelight bulb?
Cheers

[arosboro]

Hi @vkolotov I've been using these bulbs Misfit Bolt They are $20 on amazon, and have a Misfit home app which supports light scenes with I think a list of 10 color presets that alternate. Also supported is wake up timer.

[vkolotov]

But this is not a Yeeligh bulb, right? If so, pls create a ticket for your bulb. I'll close this one as afaik Yeelight bulbs are discontinued.

[arosboro]

I think this is a re-branded yeelight. It responds to the same bluetooth profiles and afaik may also be discontinued as Misfit was acquired by fossil. I cannot tell if there is surplus or if these are being manufactured still as they are easy to find on ebay and amazon.

[vkolotov]

I'll try to help you with it (with your help), but I won't be able to buy it as they are discontinued indeed.

[arosboro]

Thanks, I can program, but I haven't touched C++ or Java since 2009. I currently have this set up with PIR to turn on and off connected to a raspberry pi without open hab.

[vkolotov]

That repo on github is a bit crappy, hard to understand the protocol and what characteristics are used (UUIDs). I'll need to get a list of services and characteristics UUIDs.

Please use gatttool or bluetoothctl (this one preferable as it also gives handler IDs) to get a list of UUIDs for me.

Cool, thanks. Try to connect to that device via bluetoothctl, it will give you a full list of characteristics etc.

The one you've provided is a list of services.

[arosboro]

I think this is what you need:

Do you have the yeelight pdf documentation as well?

[vkolotov]

Actually... you don't have to use any of those utilities. Just use binding. It will give you a list of characteristics if you enable "Binary only" for the "GATT parsing Strategy" setting on the binding preferences page.
