So please try arduino v1.6.5 - it works for me...

I ran a quick test to confirm your issue. Step 1. I excluded my Z-Uno from my raspberry controller (set controller to exclusion, then 3-click B button on device). Step 2. I downloaded and flashed this sketch: https://z-uno.z-wave.me/examples/bh1750/ Step 3. I included the Z-Uno on my Z-Way controlle...

I have BH1750 but I have not yet tried it on a Z-Uno. If I find the time this week, I'll try it and find out if I get the same "%" display issue.

I think the Z-Uno website has answers to your questions, but I understand you might not have found them and also the explanation might not make things clear. Let my try... https://z-uno.z-wave.me/Reference/Z-Wave/#Channels I quote: "You can also partially control Z-Uno without using channels: f...

Oh, OK. So I'll have to try an alternative approach. Or just use APA102 instead of WS2812 (and bitbang the data and clock).

Up to 21 pixels the color wheel works. But at 22 pixel stuff gets weird. I guess you need 3 bytes per pixel (one for each color) and 4 bytes per colour, if I understand the implementation of NeoPixel::show() correctly. So 21 * 3 * 4 = 252 bytes. And for 22 pixels you need 264 bytes and that is > 256...

@PoltoS thank you for elaborating. Will this be a public test? Or how to volunteer in private beta testing? I would like to use custom parameters, to design an enhanced version of the existing MH-Z19 CO2 sensor example.

This is a know issue - when the chip boots up, it sets all to INPUT and then only in setup() values are restored. We are working on this problem Thank you for confirming this. I will continue my work on a nice working example when the known issues have been resolved. Please contact me if you want m...

Thanks. New issue. Probably again missing some info. See code below. If you run this minimal sketch, you'll notice the LED turns off when the Z-Uno receives a command from the controller. My code never turns off the LED, so it has to be the Z-Uno runtime. Is there any way to avoid this? I'm guessing...
