Just to be clear, is this with Alex10 on a PC or HG on a Pi?
HA-Bridge now has a Helper for HG. This makes setup very easy to intergrate with HG.
Amazon has updated the way Alexa comunicates with emulators so all emulators like HA-Bridge must now use port 80. Any thirdparty software used with HA-Bridge (like Alex10) must point to the correct IP and Port of HA-Bridge.
