thank you for quick reply. Iris 3210 is still not the most cost effective solution.
I do read that xbee can be used as zigbee repeater here. However the post is not clear and I am not sure how to use xbee as zigbee repeater. Is there a concise post about how to use xbee as zigbee repeater?
~$30 is a bargain for two repeaters. If you’re not willing to find the instructions and go through the setup of the xbee, then the price you pay covers the convenience.
