- | ====== 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/ | ||

- | ===== 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) | ||
- | | S | PIR | 1 Int! | Immediate | ||
- | | S | Temp sensor | ||
