Individual Color Picker for an (arduino) RF-RGB-LED-Receiver ?

---

I’m looking for a colorpicker or something similar to give RF SIgnals for RGB Codes to an homebrew RF-Receiver-LED-Driver.

On hardware it is already working with a simple 433Mhz RF and can also be controlled via pimatic with a HomeduinoRFButtonDevice with some single buttons. I actually realized ON/OFF/R/G/B and did some more codes for special light colors by buttons.

Already thought about some kind of codes to submit color with different bits like in this example (running in my house already).
Did it like this: “command”: “code:BBGGRRxx”
//code is with bits where xx are special codes for ON(01) and OFF(10) and 50%(11) shortcuts without changing the color and BB/GG/RR is each 2 bit for RGB-color.

My wish is now: Adjust the color by a GUI element (~colorpicker) and give codes for that to RF Homeduino.
Anyone an Idea for that? Ofcourse I can change anything in receive protocol of arduino

@DDNRN
I don’t know if its the best solution but you could add a pimatic-led-light device and use the color variable of the device

You can then add a rule like
if $moodlightpc.color changes then execute " [add special command to set your code to var:$moodlightpc.color] "

somesthing like this would be cool:

https://www.npmjs.com/package/color-picker

if you use a pimatic-led-light device its exactly like this:

@thymian Thanks, good Idea so far.
Didn’t use it till now because I don’t know which setting for config to use without having real device?
I should need a kind of “dummy output device” for this LED-light GUI-device. Get a lot of errors with every action.

And second question: Can someone explain a way to give this individual hex code to Homeduino and send it with an additional “house”-code?

Anyway I’ll try something with playing a bit around …

Is it possible to create a kind of dummy for e.g. Wifi370 device on the local machine 127.0.0.1 outside of pimatic?

Actually, pimatic-led-light contains a DummyLedLight which may work for your use case. You should be able to pickup its state as part of rule predicates (color, brightness, power, and mode). If you have installed the pluin, make sure to grab the latest version from github master.

DummyLedLight

[pimatic] warn: no plugin found for device “dummyled” of class “DummyLedLight”!

@n3ro Did you install the master from github? DummyLedLight was added 4 months ago and is more recent than the npm package

Sorry for that but how to install the Plugin from Github instead of NPM-automatic?
I know there was a small explanation in the flow of another thread, but can not find it.

Maybe a job for the HowTo Section also

@DDNRN Here you go.

Please make sure have pimatic-led-light installed (the normal way via UI). Please also make sure you have git installed on your Raspberry. You can install it using the sudo apt-get install git command sequence.

Then perform the following steps:

sudo service pimatic stop
cd /home/pi/pimatic-app/node_modules/
sudo rm -rf ./pimatic-led-light
git clone https://github.com/philip1986/pimatic-led-light
cd pimatic-led-light
npm install
sudo service pimatic start

Perfect! thanks @mwittig (and saw the HowTo also!)
With dummy device it’s working and I can play with the values from Sliders and ColorPicker.

Now my last problem is to send individual RF codes from these values via homeduino to my devices.
Is there any way to give RF commands with codes to Homeduino without using predefined codes from existing devices?

Nearly same question already here, unfortunately with no answer:

Did you build the RF receiver yourself or is it part of the RGB-LED kit you bought? If the latter is the case do you have remote-control for it? If yes, this can be used gather sniff the protocol messages and add a protocol implementation to homeduino.

I build it myself, so there is no fixed protocol for that.
Actually I use the simple “HomeduinoRFButtonsDevice” : “led2” - device with different manual edited codes like “command”: “code:00000011”. >>"code:BBGGRRxx"
In arduino receiver I use RCSwitch. For decoding signals I take the code and subtract the fixed ID. The rest is in the moment only 8 bits, you can see some Info in the starting post.

For the moment ist working quite good with 5 buttons because I use nearly white light, just colored a little bit to get a bit of different color in the white to give a little blue in the morning up to red in the night. Its just to have ambient light from the ceiling.

My wish was to get a real RGB adjustment on the GUI but to control the colors also with rules to any color depending on other vars from the system/room/time/weather …

Is there maybe already another protocol I could use, making it easyer to use color-picker in pimatic with homeduino?
First I thought to extend the pimatic-led-light plugin myself, with a device for sending this RF for me, but I never used JavaScript before and think it’s to much for my skills and my small free time.
