@metalrooster: what you described sounds like is already supported by the HTTP station feature. Specifically, you can set a zone to be an HTTP station, giving it a custom HTTP command to send out upon opening or closing the zone. The physical valve connected to the zone will operate normally, but in addition, the controller will send the HTTP command specified. The HTTP commands are limited to ‘GET” commands — you need to check WeMo’s API to see if you can use HTTP GET commands to turn it on/off.
