Not really... If you add the Z-Uno to the controller, then for example add a relay, you can send data from the Z-Uno to the relay. Now you can remove the controller, it does not play a part in the communication. This more or less does what you ask: communicate, without a controller. But... Suppose o...

I understand why you didn't "see" it in that document, I must admit I've been doing Z-Wave for many years now and sometimes I fail to see stuff through newbie eyes. In this case, the devil is in the details... This sentence: "You can also partially control Z-Uno without using channels: first channel...

The fact that it shows more channels than you define has tripped up quite a few users, it is not specific to Z-Uno and it is perfectly normal. Very short answer: it has to do with backwards compatibility. Better,longer answer and more interesting Z-Wave stuff: I'd start by reading this: https://z-un...

@PoltoS Thanks. I have replaced the O/S running on my orangepizero, which was based on ubuntu xenial, by this newer version: "Armbian_5.75_Orangepizero_Debian_stretch_next_4.19.20". Then reinstalled Z-Way... And then I was able to update the bootloader of my UZB1, good! So now it has "05.26" with ne...

Running Z-Way 2.3.8 on an oragangepi trying to update UZB1 I get this: "2017-07-07 5.25 Update bootloader for 5.25 to 40196" Then when I click Upgrade: "Unable to update data. /ZWave.zway/ZMEBootloaderUpgrade" Is this a symptom of what @poltos said: "The newer fw was disabled recently. We will re-en...

Are you in the expert menu?

Do you run a recent RaZberry (or UZB) firmware?

"Note: users of eg Z-Way can find background noise in "Expert User Interface". " within which menu? where? In "Z-Wave Expert User Interface", menu "Analytics", item "Background Noise" For more information, see chapter "8 Troubleshoot the Z-Wave Network" in the Z-Way manual, it explains the advanced...

Can the Z-Uno report packet RSSI and possibly background noise RSSI? That might help to do some tests... I saw the Z-Uno debug setting has an option "Radio" but I haven't looked at it closely and I cannot test right now.

Thank you for your reply. I understand what you are saying, but the results with short extension cable are not as good as the test with the USB hub on my Lenovo. Also, I get excellent results on my MAC when UZB1 is plugged in with no extension cord at all and the macbook is a block of aluminium I th...

I think PoltoS is trying to say this: A Z-Uno always has a group 1 - you do not need to add or change any code. So on your controller, please navigate to the Z-Uno and find the button or menu to change associations. Then add the Spirit as a "single channel association" (not "multi") to group 1 and t...
