I want to place my Zmatter dongle outside my house in line-of-sight with the Zwave modules to maximize the range.   '

There is an open field between where I plan to put the Zmatter dongle and one of the controlled Zwave modules, so I can't bridge the distance with a mesh network of Zwave modules.   

I plan to use a USB-to-ethernet extender to place it 40' feet away from the Eisy.  The Eisy normally powers the Zmatter dongle directly with a USB 3.0 port .  USB standards say that a USB port supplies 5V at up to 0.9A (4.5W). 

I see on a Reddit post that some people have done something similar using a USB 2.0 USB-to-ethernet extender powering the Zmatter dongle.   USB 2.0 ports are specified to put out only 0.5A (2.5W) .  They said it worked, but the question is, how well ?

How well will the Zmatter dongle work if it is limited to 2.5W ?   Would it be expected to have better range if it were powered by a USB 3.0 port supplying up to 4.5W ?  What is the power consumption of this Zmatter dongle, it is not on the specs I can see ?

 

 

 

Why not just use a Zwave 800 amplifier/repeater. Placing the Zmatter dongle outside of the house, and exposing it to weather,  is probably not a good idea

Zooz 800 Series Z-Wave Plus Range Extender ZAC38 - The Smartest House

That's a great idea, and a less expensive option than what I was thinking.  

Good reviews for the product on Amazon with one of the few critical comments saying:

"Great product but can get directly from Zooz for 10 dollars cheaper."

 

Thank you

Still it would be good to post somewhere the power consumption of this Zmatter dongle.

I would like to leave this post open until there is an answer to that question.

Every time I've bought a Zooz device I've checked its price on Amazon.  It has always been higher on Amazon, with the difference being even greater than the shipping The Smartest House charges by a bit.  The only downside to buying direct is that it's hard to fully opt out of their annoying emails - but that's true of most companies, in my experience.

If you're looking for an answer, emailing UDI directly through their support channels is the best way to get it. 

Per UD support:

"I don't have the exact specifications regarding power consumption. This said, it should by fully functional using the USB 2.0 port."
