yeelink.light.ceiling20 vs. yeelink.light.ceiling22 #56

Closed B48D81EFCC closed 2 years ago

Hi,

I have a Xiaomi Mi Ceiling Light (this is the name on the box). Originally the device is made by Yeelight. It seems a re-branded (any maybe slightly modified) version of a Yeelight device.

The hostname / DNS of the light is yeelink-light-ceiling22-mibt1ADB (identifies as ceiling22). On the device itself I can find two slightly different model no.:

So far everything looks like it is a yeelink.light.ceiling22

BUT According to your published pinout and the photos it fits more the YLXD50YL

So some details suggest it is yeelink.light.ceiling20 and some details suggest it is yeelink.light.ceiling22

What do you think?

It looks like both versions uses the same WiFi daughter board. The difference between the two YAML example configuration is the RGB support (ceiling20 = with RGB LEDs, ceiling22 = without RGB LEDs). You should use the ceiling22 as starting point because your device is CWWW only.

Could you provide a photo of your ceiling lamp (LED driver board) without the WiFi daughter board attached? I would like to see the socket labels on the mainboard.

The photo should show something like this:https://raw.githubusercontent.com/syssi/esphome-yeelight-ceiling-light/main/images/ylxd50yl/003.jpg

Hi,

yes I can and will provide. But I can tell you already: It looks exactly like your photo and the labels are the same (R G B is on my board as well).

Do you agree to add your photos to the project under Apache 2.0 license? The pull request of ceiling22 didn't provide any photos. So that's the chance to illustrate/improve the ceiling22 support.

B48D81EFCC commented 2 years ago

Yes, sure. Feel free to add de photos to the project or do you want me to create a PR?

syssi commented 2 years ago

I'm happy about a contribution too. :-)

syssi commented 2 years ago

Feel free to close this issue as soon your setup is up and running.

Hi,

with the current documented pinout for ceilling22, I was not able to flash the firmware. TXD = TP4 RXD = TP5

The correct pinout is TXD = TP5 RXD = TP4

I will create another PR

B48D81EFCC commented 2 years ago

I was able to flash the ceiling22 firmware / configuration.

Looks very well so far! I am very happy.
