Hi,
I'm wondering how i add a new hardware device in Domoticz.
You might ask why.
Well i bought this WIFI Led light. Which connects to my wifi network.
Right now i can only control it through an app on my smartphone. However i would like to control it through Domoticz.
This is the light

I will try to figure out how to control it directly (without the app). I think i can figure that out.
But how do i add it into Domoticz?

Perhaps search the forum for Yeelight.
The starter did integrated yeelight bulbs to for his first time.
Perhaps buy yeelight works great! like Hue

Hi,
Yea, i tried the Yeelight, but that didnt work.
Currently trying to figure out with Wireshark if i can controll the lights from my computer.
I just found out that the light lissens on port 53464. How do i change the port of the yeelight?

Ok.
I have been playing around with it a bit.
I found out wich UDP package was being send through Wireshark.
I can now switch the light off and change some colors by sending an UDP package to the IP.
The question however remains. How do i add this into Domoticz?
Any help would be welcome!
Currently trying to figure out how to set (calculate) the RGB color and turn the light on.

The app sends this UDP package when i turn the light on.
However when I manualy send the UDP package it doesn't turn on.
This is the capture from wireshark, it captured my the package send from my iPhone.
Code: Select all
Frame 16: 64 bytes on wire (512 bits), 64 bytes captured (512 bits) on interface 0

[Checksum Status: Unverified]

Now when i send an UDP package with the same IP/port and data. (HEX : 7e 04 01 64 ff ff ff 00 ef ) it does nothing.
Can anybody see what i'm missing?

ok, i got it.
To see which lights are connected to the network you need to send an udp broadcast.
All connected lights will respond with their name if you lissen on UDP port 6000.
Code: Select all
Adress data (HEX) result
255.255.255.255:5000 7e 07 09 ff ff ff ff ff ef A response from each connected light with so i have the IP and their name.
LedIP:5000 7e 04 04 01 00 ff ff 00 ef Light turns on
LedIP:5000 7e 04 04 00 00 ff ff 00 ef Light turns off
LedIp:5000 7e 07 05 01 fa 1f ff 00 ef Color: Warm white 100%
LedIp:5000 7e 07 05 01 0 Color: Warm white 10% (can't go lower)
LedIp:5000 7e 07 05 01 2 Color: Warm white 20%
LedIp:5000 7e 07 05 03 fa 1f ff 00 ef Color: Purple 100%
LedIp:5000 7e 07 05 03 fa 1f ff 00 ef Color: Blue(ish) 100%
Does anybody see any logic in the color coding?
And how do i add this into Domoticz?
