This should work with Domoticz, it's what I intend to use with it. I've received the boards from China and I'm currently working on a version 2 of this board. There are some errors in the design of version 1 that I need to get out. New version will be up shortly.
I've been using processing.org to capture data from Arduinos. I haven't tried with an RPi yet, but the link here is dedicated to just that.
Processing is more geared for doing really fancy graphics, but its ability to capture data and put it to a file is great, and, of course, send data to the Arduino.
I am inexperienced in interprocess communication, but, apparently processing can put the data out to MQTT check this link
Let me know how that works out for you!
This is a simple, low-cost and quick project that can get a high spouse acceptance factor.
Mirror
Remove the led strip from the aluminum profiles.
Cut the aluminum profiles and the covers to appropriate length. I used a hacksaw to cut profile+cover at the same time to ensure the got the same length.
Cut the led strips at one of the cut points using a side cutter.
Remove the old wires (they are too short to reach the box) and solder new wires.
Put the led strip back inside the aluminum profile. Note that there is a small grove at the back for the strip, this ensures that the strip is close to the profile to maximize cooling.
Glue the profiles to the mirror. I used slow-curing epoxy.
Electronics box
Drill holes in the project box for the switch (6mm) and the potentiometer (6mm should be enough but was too tight so I used 8mm).
Drill a 4mm hole for the wires to the led strips.
Upload the sketch to the Arduino
Connect the Arduino and the battery packs and put them inside the project box.
Fasten the project box using double-sided tape.
Big thanks to my wife for letting me use the action photo.
@GertSanders it is so small indeed, soldering with my soldering iron would be a problem. Maybe a 'secret' connector for this device would help @Koresh, just mount it if you need it...
@tbowmo more out of curiosity, and from someone that just got started on electronics, so please sorry if this sounds like very noob, but, would it not be safer to plug the V_TARGET LED to the +3.3v pin? How do you ensure that the resistor on the V_TARGET will have constant voltage and that will not blow from over voltage if the VCCio pin is depended on the the Motherboard power?
Thank You and nice work

I am using them at 12V so the power would be ~4W. Not too much but still enough to get the sink hot!
The voltage makes no difference. 5A is still 5A.
you are right brain fart
