Hi,
I installed a zuno. It's 15 meters far from the controller (razberry).
The communication didn't work, so I added an external antenna. Not better...
After several tries, I found out that the communication works if the zuno is powered by the USB port.
In my project, it's powered by an external AC-DC converter (5V) via the 5V pin. The communication works only if the Zuno is closer from the controller (<8m).
Is there a difference between the power supply via the USB Port and the 5V pin?
thanks for your help
Zwave range and power
Re: Zwave range and power
There should be no difference. Make sure your AC/DC is powerful enough (sometimes people take some old 0.1 A and connect it to things like Z-Uno with many peripherals). I would suggest at least 0.5 A
Re: Zwave range and power
Maybe your DC is a little bit dirty and disturbing the Z-Wave communication.
You should try a different power supply.

Re: Zwave range and power
Hi,
I am facing the same issue here. I am using a Meanwell DIN 12V AC/DC power supply connected directly to 7-18V pin. Range is really miserable. With USB cable connected range is way better. Is there a way to control the power of the transmission of these modules. I am not sure about it but I think on Z-wave there is the CC COMMAND_CLASS_POWERLEVEL. I am not sure how to use it and if it affects the transmission in some way.

Re: Zwave range and power
Default power level is the maximum, so you can not improve it.
We will check if we can reproduce the same issue.
