Exploring Gleco Smart Bulb 15W RGB+2700~6500K from AliExpress: CB2L Module, PWM Details

Question

Hello,
I recently ordered some smart bulbs from AliExpress: https://www.aliexpress.com/item/1005005481268886.html

The brand is Gleco.
Smart Bulb 15W RGB+2700~6500K
AC 85-265V 50/60Hz

It seems they're pretty straightforward to work with. They have the CB2L module.

P6 PWM 3
P7 PWM 2
P8 PWM 1
P24 PWM 5
P26 PWM 4

I wrote an article on my blog about it:

Thank you, that's a very nice and detailed blog post. Can you also paste here JSON template from OBK Web App? Added after 46 :BTW: You can get GPIO roles automatically that way:

I am using similiar bulbs, also on BL602 chipset, and control them in groups via Tasmota Device Groups system:

I am trying to use tuya-cloudcutter. But couldn't find Gleco in the list of manufacturer names. Any idea how to go about it - select another manufacturer or create a custom device.json, combined.json, profile.json?

Tuya Cloudcutter profile can be created from firmware dump. If you don't have a flash dump, you can use wired method:

I have exactly the same bulb. I've managed to unsolder but not yet braved re-soldering.

my dump and info

Log in, to see the code


Device configuration, as extracted from Tuya: 
- LED Green (Channel 2) on P7
- LED Cool (Channel 4) on P26
- LED Blue (Channel 3) on P6
- TODOpwmhz
- LED Red (Channel 1) on P8
Device seems to be using CB2L module, which is using BK7231N.
And the Tuya section starts, as usual, at 2023424

finally came back to this bulb. I had soldered it back on and it didn't work, so got annoyed and left it for a couple of months.

I resoldered it today and removed two capacitors closest to the CB2L to check solder hadn't dribbled everywhere. a good clean, resolder and a cautious power-on saw it connect to my network!

@synergy4489elektroda where did you get P24 PWM 5 from? If I analyse my bin in BK Easy Flash I get this output

Device configuration, as extracted from Tuya: 
- LED Green (Channel 2) on P7
- LED Cool (Channel 4) on P26
- LED Blue (Channel 3) on P6
- PWM Frequency5000
- LED Red (Channel 1) on P8

I only see 1 other device with a matching template in the device list

The Tuya Config detector may be sometimes faulty. Maybe in this case it has omitted the missing PWM? Please try anyway. If it;s the device from the first post, then indeed there are warm white and cool white diodes.

divadiow · Answer

yes, forgot to mention. it is correct with P24 and P26 present. identical device

p.kaczmarek2 · Answer

Okay, so that's clear now. Thank you for submitting template, I am very happy with your recent activity! Please keep it on! It's very hard to maintain a large project like OBK just by myself, any help is welcome.

PS: I am also doing teardowns all the time, but some of them first go to our Polish site, see sample here, but I will enable them for our com site soon as well.

PS2: Hmm it seems I need to add a space here:


- PWM Frequency5000
