This is probably a stupid question and I think I know the answer already but just thought I would check to be sure.

Speccing a job to upgrade a client's ancient Pronto Pro setup involving 8x TSU9600s all talking to various bits of kit including a couple of Kaleidescape players.

In order to simplify job and ensure good stable coverage across what is a large house with thick walls, was hoping to do away with two way comms and just use a couple of 433 antenna's with an XP6.

Is there any reason why I cannot use the 433MHz RF comms protocol but still use the IP Kaleidescape driver for 1 way comms only?

No that will be fine.

All your losing when utilising 433 over zigbee is feedback.

All the actual control is done by the processor.

If you have a t2x or t3x you can get your feedback from wifi.

Thanks, that's what I thought but just wanted to be sure
