I am using one myself on a Vera3 controller. It uses the multi channel Z-Wave command class. This means special support would need to be added, indeed alike to other modules using the same method.
Individual power usage reporting is also possible, but it is not easy. Been dealing with Vera tech support to make mine work correctly. Still waiting on Aeon Labs to reply to my request for the engineering documents.
Plan to get two more if I can get this first one to work all the way with individual power reporting.
The variable IDs I have so far are:
4 (Enable Report Filter), 1d, 1
5 (Delta Watts [Master]), monitor, 25
6 (Delta Watts [P1]), monitor, 25
7 (Delta Watts [P2]), monitor, 25
8 (Delta Watts [S1]), monitor, 25
9 (Delta Watts [S2]), monitor, 25
10 (Delta Watts [S3]), monitor, 25
11 (Delta Watts [S4]), monitor, 25
12 (Delta Percentage [Master]), monitor, 5
13 (Delta Percentage [P1]), monitor, 5
14 (Delta Percentage [P2]), monitor, 5
15 (Delta Percentage [S1]), monitor, 5
16 (Delta Percentage [S2]), monitor, 5
17 (Delta Percentage [S3]), monitor, 5
18 (Delta Percentage [S4]), monitor, 5
80 (State Change Report), monitor, 0
101 (Report 1 Content), 4h, 0100
102 (Report 2 Content), 4h, 0001
103 (Report 3 Content), monitor, 0
111 (Report 1 Interval), 4d, 1
112 (Report 2 Interval), 4d, 600
113 (Report 3 Interval), monitor, 0
*P1+P2 = power switches that are always-on when the master is on
*S1-S4 = power switches that can be controlled individually
The Master switch is reporting power usage in real-time at the moment, as well as for S1, just not S2-4 yet. When the master switch is turned on (even with multi-channel support) then S1 through S4 turn on as well, which is what you experience with HomeGenie right now as it needs to seperate S1-S4 for individual control.
