EDIT: Updated 14th June 2017 to reflect version 4.5.5. Default port is now 80 to keep Google Home happy and service now supports MQTT! Advice on backups also added 7th Feb. Version 4x also supports adding a Home Assistant instance which is great! Want to control your Vera, Harmony hub or Home Assistant entities with your Amazon echo or Google Home? ha-bridge is the best way to achieve that and installation is actually quite easy and takes less than 5 minutes. Here are the steps.

[See 2nd option at the bottom for the alternative fix] If your Harmony remote won't turn off your PS3 using bluetooth (but turns on OK), modify the power settings for the Power Off so they like like mine below. Seems there is a bug in the Harmony software that mixes up the cross and circle depending on what region you're in.
