Hi all.  I just ordered a "ZMatter USB: Z-Wave+ & Matter Module for eisy" and forgot that I will install it in my networking cabinet. 

Are there any recommended antennas?

Also, what is the connection type since I likely have to run an extension cord. 
Eg, will any RP-SMA WIFI antennae work? 

Thanks!

It comes with (1) external Zwave antenna and (1) Zigbee external antenna. The antennas are tuned for the proper frequencies...I believe it is a standard SMA connection.. 

The Zmatter enclosure has a standard USB connector. You can locate it outside of your cabinet using an USB cable which connects to the USB port on the EISY.

Thanks for the info both!

I wasn't sure it came with antennas, but that makes sense. Good idea on the USB extension instead of antenna extenders!  Heading off topic, but has anyone used a USB splitter with their EISY?  I wasn't sure if it would support those drivers.  Honestly I'm not sure what I'd use one for at this point... but after using the ISY994 for ten years, I'm not sure the "art of the possible"

Thanks again!

The ESY has four 3.0 USB ports so there's really no need for a splitter.

Good point - thanks TM.

@MMotion, I have another option you might want to consider.

I'm currently testing the following product which allows me to mount my eisy in my equipment room and remote mount my ZMatter assembly and PLM in a location best suited for the best RF connections.  That location is more than the allowed 16 ft for USB 2.0 and already has an available ethernet port:

So far, the testing has been successful, but I need to do more testing to convince myself there is no degradation in performance with this setup.  This unit uses a single ethernet cable to extend 4 USB connections up to a claimed distance of 196 ft from the source computer.  This particular unit is unique in that it supplies power through the ethernet cable from the transmitter to the receiver to power those end devices.  Most of these units inject power at the receiver.  I wanted something that would remained powered with eisy via my equipment room UPS.

With this setup, the ZMatter dongle and PLM are plugged into a single receiver being feed by a single USB connection on the eisy side via the ethernet cable.

Let me know if you'd like more details.
