Xiaomi Desk Lamp support

[dh-harald]

Hi,

I've a Xiaomi/Yeelight Smart Desk lamp (https://www.mi.com/global/smartlamp/). It would be nice, if Tasmota could support it.

It has 2 opensource firmware already:

https://github.com/Torxgewinde/Desk-Lamp-Alternative-Firmware

Nice complete product.

But does it provide enough light? 300lm is not much for a desk lamp...

Please, try Tasmota with the generic module configuration and set the gpios according to this hardware to test. You will need to find out which gpios of the esp8266 are connected and to what. Thanks for share. Keep up posted.

Hi,

Based on the existing firmwares, I've set the following:
D4 GPIO2 -> Button1 (17)
D2 GPIO4 -> PWM1 (37)
D1 GPIO5 -> PWM2 (38)

With this settings, I could turn on and off the lamp via pressing the button, and I could set the brightness and the color temperature on the web frontend... (toggle button worked as well)

Unfortunately (I think), the rotary switch needs extra work from your side...

Yes, the rotary switch functionality is not available in Tasmota.

And also the hardware. You can send one of those lamps to Theo.

Yes, the rotary switch functionality is not available in Tasmota.

In this case, I'll try to implement it. Fingers crossed :)
