Z-UNO

Thanks a lot for this information. Just ordered my module.

Regarding the floating point issue. Is this also caused by sending floating point or by calculating it in the sketch? If it is because of sending you could send integer values instead and divide by 100 or so in Indigo.

The way I understand it is floating point values are not sent. For a precision of one decimal place, I pass that value * 10 to the ZUNO routine.

From what I'm reading on the forums, it looks like it's possibly a stack issue in calculating floating values in the sketch. Not 100% sure though. I figured I'd wait until the latest release, and then re-do my code/device to report integer precision. In my case, the device is a bit difficult to get to...

I just wanted to say it works perfectly!

I have now a device sending two multilevel sensor data and additionally a dimmer for an LED strip.

Our imagination is the limit.

Really cool

Glad you got it running. Below is my sketch, and the info from Indigo about it.

Thanks a lot for sharing.

I'm still learning a lot. Right now I'm stuck at how I can make zunoSendReport for multiple sensors. It looks like it just sends channel one even if I use zunoSendReport(2).

I haven't done multiple channels, but it looks like you need multiple calls (one for each channel) to ZUNO_SENSOR_MULTILEVEL() within the ZUNO_SETUP_CHANNELS() call.

BTW, the '1' in my ZUNO_SENSOR_MULTILEVEL() call defines the units as Fahrenheit. Being a European company, they don't have a #define for Fahrenheit, but Celsius was defined as a '0'. I took a chance and set it to '1', and that worked for Fahrenheit.

Anyone using the "Multicommand Enabled" mode? Does it work w/ Indigo?

Yes, MCA work.
