Took delivery of the EcoNet.. easy to install, paired up as "Device", had to change to "Generic Z-Wave Valve". Appears to be well built - the mounting is a slimmer design that attaches to the brass part of the valve and the claim is it does not stress the copper piping - The Dome unit attaches to the copper pipe directly above the valve but is longer and more spread out distributing any potential load so I'm not really sure if that is an issue or not.
When opening or closing the motor sounds somewhat rough (almost gravel-ly) but seems to work fine. I am going to try and hook up a contact sensor to use as a secondary verification that the valve has been closed.
The Dome Z-Wave issue may have been caused by my old z-wave devices and was eventually able to get it paired and working again but decided to replace anyway. Will use the Dome as a backup or maybe for some other lever..
