Planned features 1.4

• New option to enable "ack" when sending message between and from sensor to gateway. Actuators need this to confirm that messages has been delivered.
• Send all data binary instead of ascii beween sensor/gateway and vera. Will save space and computation power and reduce program size. Allow binary data transfers.
• Queue incoming radio messages and serial input. Q: Really necessary?!
• Add Lock device type
• Add example for RFID tag device.
• Add example for a simple door/window sensor.
• Add support for window covering device with examples using stepper motor and servo.
• Send/receive IR commands vera device and example.
• Example sketch for measuring meter pulses using a light sensor. Sensor reports watt/KWH to vera
• Non invasive current sensor
• Support for setting channel in Vera gateway and sensor sketches. Still a bit unclear how this should be archived in simple manner.
• AES Encryption? Q: How should keys be exchanged? Q: How to handle replay attacks?
• Support TCP/IP as an alternative to USB/Arduino serial connection
• Receive/send data to 433Mhz devices. Much of this depends on library support.
