..... I'm envisioning something like a Bluetooth or WiFi dongle.
With current technology.... I don't see why the firecracker couldn't be made in dongle form. But the firecracker itself.... is limited in use. I am not sure there is a huge market for the firecracker. I have both the old serial and the new USB.... but I don't use ether one.
I do use a Home Automation computer which is admittedly attached/bound to a CM15A. I guess I could use the AHP software and only send and receive RF signals (with a firecracker).... but I would lose the detection of the PLC signals.
You could use a Home Automation PC connected to a CM15a... then connect to that PC with something like
logmein. That would give you the total wireless freedom you'd like. Yet still the total Home Automation control everyone wants.
