Found it! there is an inverted logic now if you call digitalRead with constant parameter. Will fix it...

You have to control relay via its nominal voltage. I don't know what schematic was used for your relay module, but by default Arduino Uno use 5V logic, when Z-Uno use 3.3v logic. To control it you can use some attional drivers: channel transistor, darlington array etc. The most simple way is to conn...

It sounds strange... If you see that LED changes its state it means that PIN13 changes its state too. You can check it via multimeter. White LED connected directly to PIN13. May be you connect relay control to another PIN? PIN13 = PW1 (see http://z-uno.z-wave.me/technical/pinout/). Your code have a ...

In this case I need a sample of your code.

Thanks to all the programmers of the Z-UNO firmware! Using the new Features of GPT and external interrupts I was able to analyse the protocol of my Mitsubishi A/C. I connected the IR - receiver to the ZEROX (Pin 3). With the GPT I measured the length of the pulses coming from the IR transmitter. No...

I missed something, but I don't understand how do you log events? Do you log them from Z-Uno? If you use UART0 to output there is no differences between 2.0.7 and 2.0.8. It works sequently byte by byte. DMA is using only for input data. Input buffer is 64 bytes long. It's cyclic. So, if you write 65...

The problem is in code for reading light level. It wasn't updated to match new Wire library. The fast fix is https://github.com/Z-Wave-Me/Z-Uno-Core/commit/20503d41af7764d8102fabf49d94f9f2baf09535 inside BH1750 library. You can do it manually: 1. Open folder with preferences.txt of ArduinoIDE (hyper...

The hardware limit is 15 bytes in the case we get the maximum amount (511) of raw bytes to IR controller. I Don't think that you really need 18 bytes. Can you sniff sequence with logic analyzer?

Did you try "10 channels" example? If you have problems with it too then you have to seek for the problem inside your controller. This sketch was certified and works right.

Z-Uno is a slave(like any other relay module/sensor/ etc.) in the terms of Z-Wave network, so you need a Z-Wave controller between Z-Uno and your PC/phone.
