+node-red-node-timeswitch
+========================
+
+A Node-RED node to provide a
+simple timeswitch node to schedule daily on/off events.
+
+Install
+-------
+
+Run the following command in the root directory of your Node-RED install.
+Usually this is `~/.node-red`
+
+ npm install node-red-node-timeswitch
+
+Usage
+-----
+
+Sets **msg.payload** to *1* during on times, and *0* during off times.
+
+Also uses the suncalc module to allow use of dawn and dusk.
+
+Dawn and dusk times can be offset both positively (+ve) for minutes after dawn
+or dusk, and negatively (-ve) for minutes before dawn or dusk..
+
+The output emits a **msg.payload** of *1* or *0* every minute depending on
+whether the current time is during the selected on time or off time.
+
+If you just need the transitions from 0->1 or 1->0 then follow this node with an RBE node.
+
+You may also optionally specify a **msg.topic** if required.
+
+**Note**: For a more complex version with more built-in options see Pete Scargill's
+[node-red-contrib-bigtimer](http://flows.nodered.org/node/node-red-contrib-bigtimer) node.
