Works with Vera, but I wish there was a plugin to better implement it within Vera.
on January 26, 2014
I've got my WV-01 working the way I want with my Vera controller, but it wasn't nearly as straight forward as I would have preferred.
After inclusion in the Z-Wave network, Vera sees the valve as an appliance module, with the states being ON (closed) or OFF (open). To me, it makes a lot more sense to treat the valve as a relay, with the states being open or closed, so I changed it to a relay device type by doing the following:
On Vera, after pairing, select the device and go to the settings under the Advanced tab.
Change the "device_type" parameter from "urn:schemas-upnp-org:device:BinaryLight:1" to "urn:schemas-micasaverde-com:device:Relay:1"
Change the "device_file" parameter from "D_BinaryLight1.xml" to "D_Relay1.xml"
It was my desire to be able to use scenes in Vera to open the valve when we are home, or close the valve when we are away. I later plan to add some moisture sensors, which when triggered, will cause Vera to close the valve. The valve has two modes, Water Alarm Mode, and Water Level Mode. I would have thought that Water Alarm Mode would be the one that I'd need, but it turns out that only Water Level Mode will let you remotely open and close the valve at will. In Water Alarm Mode, Vera or a sensor can close the valve, but it can only be opened manually by pressing the "Open" button on the front panel of the valve. This might be just what some folks want, but it was inappropriate for my needs, so I had to switch over to Water Level Mode. By the way, if included in a Z-wave network and configured for Water Level Mode, the attached water probe is disabled. Another thing that threw me for a loop for awhile is that when the valve is in Water Level Mode, there is a timeout value that is used that says how long after receiving a close command the valve will wait before accepting an open command. This value defaults to 60 minutes.
Vera allows these options to be set under the "Device Options" tab.
To change the valve to Water Level mode, under the "Device Options" tab, press the "Add configuration settings" button, and enter the three following settings: "Variable=0", "Data Size=1 byte hex", and "Desired Value=FF".
To change the Water Level Timeout value from its default of 60 minutes to zero, under the "Device Options" tab, press the "Add configuration settings" button, and enter the three following settings: "Variable=1", "Data Size=2 byte hex", and "Desired Value=0".
There is one thing that was a little less than perfect with my valve. There is a cam on the motor shaft which opens and closes a switch when the valve reaches the open or closed position. The cam on my valve could have used a little better quality control. Although the position of this cam is adjustable, and I did try to adjust it properly, I think mine is just a little out of spec. When adjusted so that the ball completely closes in the Closed position, when it rotates to the Open position, the ball is just a few degrees out of position, giving what I would estimate as about a 5% reduction in water flow. To me this is just a minor annoyance, not warranting the return or exchange of the valve.
Overall I am quite pleased with the valve, but the time and effort I had to expend researching how to set up the device with Vera, the rather high price, and the less than perfect positioning of the ball valve keeps me from giving it a full 5 stars.
