Python interface between the UDI ISY and HABridge
Why would I use this to control ISY devices with Alexa or Google Home instead of just using the Portal?
Harmony Hub's support Hue, so using this emulator allows controlling with Alexa, Google Home, and Harmony. Controlling lights with a Harmony Elite home control buttons is awesome, even when we can do it with voice control sometimes it's better to just to push a button.
Control scenes as groups, so light levels can be set for a scene together!
ISYHelper was created before there was a Polyglot, then idea was to allow an easy way to add modules to support any functions. It worked great to create a Hue Emulator, WeMo Emulator, Harmony Hub Interface, IP Camera control, IFTTT/Maker ... But with the Portal supporting Maker, and Polyglot allowing control of cameras, it's not a as necessary.
The other big reason is that ISYHelper does not store a persistant database so after each restart, the Hue device numbers may change, which is a problem for other hubs, like Harmony, which use these device ID's for linking. To fix this in ISYHelper would have required a lot of work, and I decided to try ha-bridge instead.
The original ha-bridge has matured a lot and now has a nice REST interface for adding/removing devices and controlling the state. This allows ISY devices to be added on the fly, and allows tracking the current state and brightness of ISY device levels back to the ha-bridge.
The interfaces needed to to communicate with the Alexa, Google Home, Harmony Hubs keep changing which required updates to the PyHue and PyHarmony recently and ha-bridge author is good at keeping up with those changes.
The ha-bridge supports creating command sequences on the Harmony and linking those to a device in the Hue Emulator. This allows you to add a Hue device called "ESPN" so you can tell Google Home "Turn on ESPN". These could be done also by creating an ESPN activity on the Harmony, but I don't want to create an activity for every channel I watch.
For an ISY device or scene to be enabled and sent to the ha-bridge you select the object in the ISY Admin Console, right click and select 'Notes'. In the notes there is a line to enter the Spoken property.
If you set the spoken property to just 1, this tells ihab to always use the devices name as the spoken name, if you want to use a different name then just enter that name.
If you set the spoken on a controller of a scene, this tells ihab that you want the abiity to control direct brightness levels of all responders in the scene at the same time. So you can say 'set yourname to 30 percent' which will change ALL responders in that scene that are dimmable, to 30 percent. You can also dim or brighten the scene, which will set all devices to the new brightness sent by Google Home or Alexa. Note that when it is turned on or off, the ISY scene is controlled, so if you have other responders like KPL buttons, they will still turn on. This could be enhanced further to dim/brighten each responder based on their current level, but I don't really have a need for that, so it hasn't been done yet. The current brightness of the controller is pushed to ha-bridge so any brigthen or dim commands are based on it's brightness level.
If you set the spoken on a scene, then that scene will be controlled directly. so you can not dim, brighten, or set the scene to a percentage.
These two methods work very well for my enviornment, and makes my wife happy because things just work as one would expect. But, if you have different requirments then please let me know.
If you rename a device on the ISY then you must restart IHAB. This is an issue with PyISY that needs to be fixed...
