I've been successful with the Insteon integration..
Right now, I've got a PLM AND an EZBridge, some devices on the PLM, some on the EZBridge...
Each device sees the other's traffic... it's frickin cool watching the logs...
AND they respond to manual commands eg. you turn a light on manually... BOTH devices see the command... and execute an event.
once in a while, they actually step on each other! hehe, but they timeout and resend, and all is well...
I'm getting about 3 commands/second throughput - that's Sending the command, receiving ack from the sending device, and then receiving ack from the child device itself.
when I use my fiire chief, it follows my hand movements pretty close...
have a few features still to work in... but even now, it's VERY useable.
HTH
