Well, here's a little update. This isn't my ultimate plan as I would like everything under one roof, but I did have some success using the wireless control of my current system to send an x10 command from a palm pad to HA and turn on a zigbee smart bulb.
I'm running a program call Home Control Assistant using a cm11a for plc and a w800usb for wireless reception. In HCA I have the option to create programs that can be triggered by wireless reception. In those programs I can send HTTP Post commands. I was using this with IFTTT's webhooks service. Press F6 on and HCA sends to IFTTT which sends the on command to Wink. It would take 2 to 3 seconds for the light to turn on.
Now I have HCA send directly to HA using the rest api and the same light turns on in about 1 second. I have Wink connected to HA.
I did one more test. I have a zwave/zigbee stick setup in HA. I setup a test sengled smart bulb directly in HA using the zigbee stick. Running the same http post the light turns on instantly, no delay at all.
So if I can't get HA and HeyU setup like I want, I at least have an alternative. It won't be my ideal setup as I'll have to run 2 systems, but at least I'm all locally controlled without any delays.
