 1. Motion detection requires a wall control panel with a built in motion detector such as the 880LMW. On Security + 1.0, motion detection is reported when the light turns on.
 1. Security + 1.0 openers can report door status over the data line, but not all wall panels are compatible. ratgdo listens for a wall panel to communicate with the door, and if it detects one (such as an [889LM](https://www.google.com/search?q=889lm+liftmaster)) or [041A7928-3MC](https://www.google.com/search?q=041A7928-3MC+chamberlain) it listens and reports the door status. If ratgdo doesn't hear wall panel communication then it switches to emulation mode, where it streams the query commands necessary to get the door opener status. Emulation mode will cause analog wall panels (e.g. [78LM](https://www.google.com/search?q=78LM+chamberlain)) to not be able to control the lights or lockout the wireless remotes because their analog commands will be ignored by the door opener.
 1. All yellow learn button openers are Security + 2.0 EXCEPT the jackshaft wall mounted 8500/RJ020 & 8500C/RJ020C which use the Security + 1.0 protocol.
+1. Not all red learn button openers support digital communication. If a red button opener doesn't use digital communication, it will not respond to door open/close commands and it will not report the door status. In such cases, use dry contact control instead of Security + 1.0 control.

 ## Will ratgdo work with my garage door opener model?
-Any residential door opener made in the last 25+ years by Chamberlain/Liftmaster should work. If your opener is mounted over head and has a **yellow** learn button, it is supported by ratgdo hardware v2.0 or greater. If your opener is a wall mounted jackshaft opener or has a **red, purple or orange** learn button, it is supported by ratgdo hardware v2.5 or greater.

 * you have limit switches which close to ground for sensing when the door is fully open AND fully closed.
 	* some models provide user accessible terminals for the built in limit switches, otherwise you have to add your own external switches. A pair of inexpensive magnetic reed switchs is the best way to add these if you cannot use the door opener's built in switches.
 
+## Can ratgdo control gate openers?
+Most gate openers can be controlled using the dry contact control interface. Limit switches are required to get the gate status (the same as with a dry contact control garage door).

 ## Which control protocol (Security + 1.0, Security + 2.0, dry contact, etc) do I need?
