I am using an echodot, but sinds 0.37 somewhere I always get the message: 17-04-03 23:25:26 WARNING (Thread-10) [homeassistant.components.emulated_hue] When targetting Google Home, listening port has to be port 80
Just specify listen_port to 80. Also, make sure to read the Torubleshooting section at the end about permissions when binding to port 80 (if you are having problems with this).
