As an alternate, replace the X10 module with an Insteon outlet. You'll have to buy a 2245 hub, but, if you're just handling a single outlet, the direct PLM driver @cwwilson08 created will work fine. It's not the best driver to use for switches and dimmers, but if you were going to use a Zigbee outlet, then it's clear you were not interested in the load sense feature.
It's $50 for the dual relay outlet and $67 for the 2245-222 hub. Control will be direct from HE to the hub.
