Zwave range and power

Post by coco82 » 04 Jun 2018 23:15

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

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

My AC/DC can supply 1.5A.

Maybe your DC is a little bit dirty and disturbing the Z-Wave communication.
You should try a different power supply.
