-====== Idea ======
-The idea is to have a device / firmware that can be configured somehow to support different (simple) sensors like switches, reed contacts, movement sensor etc.
-This would allow to have one device places somewhere and attach several sensors by cable. Example: Device placed between window that detects motion and window state (open/closed).
-===== Issues =====
-  * Not everything can be supported by one firmware
-  * Firmware has to be changed to be more modular so support for different sensors can be commented in/out easily. -> One could then make a **small** number of such "multi purpose firmwares".
-  * How to transmit status? -> One packet (defined new) or one per sensor (more modular).
-====== Possible Sensors ======
-List of sensors (with possibility to support with few code lines) that may be supported:
-^ Sensor / Actor ^ Type                           ^ I/O pins    ^ Reaction type    ^ Code complexity     ^
-| S              | Reed contact (window state)    | 1           | Immediate         | Easy I/O            |
-| S              | PIR                            | 1 Int!      | Immediate        | Easy I/O            |
-| S              | Temp sensor SHT1x              | 2           | Poll ~5-10m      | complex (protocol)  |
-| S & A       | Thermostat HR20/25         |  2        | Poll ~5-10m, Request | complex (hardware dep.) |
-| S           | DS18x20 onewire thermal sensor | 1 | Poll | complex (protocol) |
