Switch Bindings 2.0 Release!

Today I release Version 2.0! This is a major overhaul with some great new features. (Thank you for the suggestions!)

• Toggles to let you choose which attributes/events to sync
• Syncing of Held/Released events on dimmers and switches. For example, it can start ramping the other dimmers up/down as soon as you hold the paddle on another dimmer. You don't have to wait for the Level attribute to update at the end.
• Now can sync Hue, Saturation, and Color Temperature
• Includes a fix specifically for supporting Hue smart bulbs
• Miscellaneous bug fixes
• Refactored code for cleanliness and readability
• Full unit test suite, to ensure quality control while adding new features.

Switch Bindings app for Hubitat

An app for Hubitat that binds two (or more) switches/dimmers together. When bound, if either one turns on or off, the binding will make the other one also turn on/off. It will also sync dimmer levels, if any of the devices are dimmers. (It works a lot like a z-wave association, but it happens in the Hubitat hub, so that the hub can know/display the updated device states. Because the Hubitat is local, the binding can happen effectively as fast as z-wave messages can travel.)

Examples of Usage

• Suppose you have a smart wall switch in your living room that controls the overhead can lights. Now you add a lamp in the room, and you either put a smart bulb in it, or plug it into a smart outlet. You can use this app to bind the wall switch and the lamp together, so that all your lights will always turn on and off together. They will stay synced whether you control them using the wall switch, an app, or Alexa or Google Home.
• 3-way and 4-way lighting controlled by software, not wiring in the walls
• Sync a fan and a light switch
• Sync levels across a roomful of dimmers.
• With a 5 button scene controller keypad. My driver exposes the buttons/lights as virtual switches. By using Switch Bindings alongside this, it becomes easy to keep lights synced with the scene controller.
