## Raspberry Pi Library for Power Management

This library shutdowns and restarts after certain time a RPi+WittyPi combo.

It runs in the device not in the cloud.

## API

    lib/proxy_iot_nap.js

## Configuration Example

### iot.json

    {

            "module": "caf_rpi_nap#plug_iot",

            "name": "nap",

            "description": "Access to shutdown/delayed restart for this device.",

            "env" : {

                "maxRetries" : "$._.env.maxRetries",

                "retryDelay" : "$._.env.retryDelay",

                "deviceRTC" : "process.env.DEVICE_RTC||/dev/i2c-1",

                "deviceAddress" : "process.env.DEVICE_ADDRESS||0x68",

                "allowMock" : "process.env.ALLOW_MOCK||true",

                "shutdownCommand" : "process.env.SHUTDOWN_COMMAND||shutdown.sh'

            },

            "components" : [

                {

                    "module": "caf_rpi_nap#proxy_iot",

                    "name": "proxy",

                    "description": "Proxy to shutdown/delayed restart service",

                    "env" : {

                    }

                }

            ]

    }

where `deviceRTC` and `deviceAddress` are associated with the i2c interface that the WittyPi exposes. `allowMock` simulates shutdown and restart with error messages. Mocking only changes behavior when there is no i2c device, avoiding component error in that case.
