You can currently access the bridge with a smartphone or any device that has a network connection inside your network.
You can also do it if you port forward However I strongly advise against this.
Why? Because from the bridge anyone can create a script and activate it as there is no security yet coded into the bridge.
I've thought about reworking X10Relayer or Ultralight to enable them to interface with Alex10 and the bridge. X10relayer would then allow a TAC (android app) interface.
Ultimately it would be best if the HA-Bridge had some security built in then one could pass commands directly to it from a smartphone.
I've been putting off doing anything on this front as I'm not sure what the demand would be.
If you'd be interested would you want voice control from your phone or a simple button press option or both.
