I just did an install of the latest build (downloaded from linuxtracker on Friday), once the installer finished, I added a micasaverde zwave controller which had my living room light switch added to it. The system detected it, I chose ceiling light for the type and added it to the living room. Now on data grid, I can go to lights and I see a on and off buttons and it works great. The problem happens when I installed a CM11A with a USB to serial adapter with a device on the same room as the zwave. I followed the instructions on the wiki and added the CM11A, then created a child device for a floor lamp with address A2. From the device tree, I can send a message to both the zwave and the x10 lamp and they both work but from the data grid now neither one of them works. I tink the problem is that both have the same button assign to them, I am saying this because when I click on the on button, it appears that nothing happens, however, I can click on flootplan on the data grid, lights, floorplan and I can see both devices listed there and both say on, if I click on the off button and go back to the floorplan, now both will say off, however neither one of them is actually turning on or off.
I am not sure if missed something when creating the x10 device to create its own buttons.
