I ran a test tonight to see how fast we could cycle the power on and off on one of the new 40kbps devices.

Our average time over 200 commands (with full acknowledgement) was under 65ms--including the serial latency involved with using a USB stick or RS232 controller.  In other words, we were able to turn an outlet on and off 100 times (100 full cycles) in less than 13 seconds.

That's fast enough for a Christmas light show.

who makes these new 40kbps devices?  When will they be available to the public?

rustytek: The 200-series Z-Wave chip (which came out last year) is around $3.00 in quantity, and it's the one that usually runs at 40kbps.  While I don't have any info to give out from the manufacturers, I would anticipate that: (a) most new products will ship with 40kbps support enabled by default; (b) manufacturers will want to start using the new chips in their products due to cost savings.

Also, all of the new products that stream small bits of data via Z-Wave (like the Sirius radio with its 2-way LCD remote) use these new faster chips.

I do know that the first 40kbps devices are either in production/distribution or should be shipping Q2.  For the user, everything should be completely seamless, and the devices will all interoperate regardless of chip speed.
