It's just begging for a pushbutton in the the very center of all those LED's....

Good point! Will consider in the next version...

@mfalkvidd said: 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

I have already published all the documentation, on my website, GitHub and openhardware.io For now I leave the node as finished. SmartHome: Wireless LED RGBW Controller – 00:55— giltesa

this kind of optic fiber is probably only plastic so for a full DIY , you can use also fishing wire with a big power led or an old chistmass tree optic fiber lighted.....

Thanks for the answers. For sure it is possible to buy an ATmega and even a full-featured debugger would be acceptable compared to the effort of porting. But still, I am very biased towards the PIC without logical or economical arguments. I did not yet work with the mysensors libraries and only browsed quickly through the github repo. Maybe someone can give me a few hints to estimate the effort deeper than just claiming it as "much workload"? What I see so far is: make the C++ code compile (translate to C with clang/llvm and compile with the XC8 compiler) create a new HAL (in hal/architecture) which seems not too much effort for making it initially working Questions: Do I see it right, that there is a linux-port available? -> I would expect much more effort to port from AVR to linux than to port it to a different MCU What about the licensing? It looks like the code is GPLv2, but in the CLA it seem that contributors need to give away their rights on the contributions and that mysensors can even redistribute the code under another license - which seems completely against the principles of the GPL. Can someone explain that in more detail?

@victus Im not familiar with this components you mention, you need to test yourself, cant help you with the technical stuff. It does not seem to be a fully functional ECG but a heart rate monitor. As epierre said above, you need to define if you want to monitor or have a fully functional ECG, its a big difference. With a monitor all you get is pretty much your heartrate and you can detect arytmias. A fully working ECG is normally made with 12 leads and is used to in detail know how the electrical depolarisation from different time and direction/place within the heart muscle works. Holter is a example of a heart rate monitor over time.

Do you have interest to try OH2 together with MySensors Ethernet Gateway to get working? I do not have enough force to push developers to make this happen. At the moment there is some problem on this, because full control is not possible. I think that MySensors Serial Gateway is working with OH2, but I don't like to use it. I like to connect my devices into LAN not cabling via old fashioned way using serial wires.

@NeverDie Thx for appreciating the work done. There will also be an open source part in the future. When and how extensive the open source part will be, remains to be seen. The release of certain information (block diagram, ..., in this post) is related to those open source parts. There are some OBD solutions, however most of them (in my experience) give back low frequency data put by the car manufacturer on the OBD-bus (CAN, ...). Therefore transients evolving directly from the battery could only be recorded if the manufacturer sends those data accordingly on the bus. Due to the small bandwidth(also because of other car data that have to be sent, ...), such battery data are sent more often once per second or less. Fast battery events (i.e. cranking events, ...) are therefore imperceptible. Unless the manufacturer processes the fast events and then sends them (once per second or less), which is very unlikely if the manufacturer does not market this feature itself. Third parties devices for high frequency sensing costs several hundreds dollars. In my experience, important battery states (especially the fast ones) are recorded by measuring and processing corresponding data directly on the battery. I agree with you about the limits related to the communication over Bluetooth. But i think Bluetooth 5.0 will improve a lot. However, WiFi will always remain an important option due to the high data throughput. The combination of both (BLE & WiFi), especially with regard to energy consumption, will gain in importance.

Thanks for the reply. I am not looking to use an LCD, although that may be the best solution. For now, I plan on creating a simple set of LEDs and buttons. I have looked over the code, and was wondering which part of the code is retrieving the status of a sensor? What if I have multiple motion sensors, how would I retrieve each unique value?
