900MHz interference between Z-Wave and Automated Meter Reader?

    I have a Home Automation system which incorporates Z-Wave RF control of lighting and small appliances. http://en.wikipedia.org/wiki/Z-Wave . In the US, Z-Wave runs at 908.42MHz.

    My water utility wants to add a Neptune R900 RF Automated Meter Reader (AMR). From the available documentation http://neptunetg.com/userfiles/file/products/R900 RF MIU Wall or Pit/Publication_IM R900 01_10.pdf, it appears that the R900 unit uses frequency hopping between 910 and 920MHz and will transmit data every 14 seconds.

    Do I have any reason to be concerned that the R900 will cause interference on the Z-Wave RF network? I do know of a case where a '900 MHz' baby monitor did kill a Z-Wave network.

    I have asked the local utility and the R900 manufacturer the same question and gotten polite but unhelpful answers to date.
