It's a python daemon to control relays connected to a Raspberry Pi and Raspbian as OS. You can program them, to turn on/off automatically. It uses the RPI.GPIO library

It runs using a config file and the following concept: A cycle it's something that is executed without stop, and it has sub cycles, so each sub cycle do an action during a time period. For example a sub cycle could turn on a relay during 3 seconds, and the next sub cycle turn off during 5 seconds.

Just download the ZIP , and execute relay/install.sh as root. It will create a folder: ~/.greenRpi where you can find a JSON config file with some examples.

sudo sh install.sh

To configure the daemon, It has 2 config files in ~/.greenPi:

• relay.json, has only a simple array with the
• config.json

Just see the config file, it's very simple to understand: The config file is a JSON array with 2 elements:

• numRelays: The GPIO numbers where are connected the relays that you are going to use. It is related with relay.json array. For example, relay.json has [21, 7], config.json should have [1, 2]. It means that in the program, the relay number 1, is the relay that is connected in the port 21, and relay number 2, represent the relay that is connected in the port 7.
• cycles: Here is where you define the cycles, it means, each cycle has:
  • subCycles: Is part of the subCycle
    • Mode: On or Off (true/false)
    • seconds: The number off seconds that take the subCycle
    • [numRelays]: (Optional) The affected relays.

Config file, example:

{
    "cycles" : {
        "test" : {
            "subCycles" : [{"mode" : true, "seconds" : 20}, {"mode" : false, "seconds" : 20}],
            "numRelays" : [1,2]
            },
        "floracion" : {
            "subCycles" : [{"mode" : true, "seconds" : 43200}, {"mode" : false, "seconds" : 43200}]
            },
        "crecimiento" : {
            "subCycles" : [{"mode" : true, "seconds" : 64800}, {"mode" : false, "seconds" : 21600}]
            },
        "cambio" : {
            "subCycles" : [{"mode" : true, "seconds" : 129600}, {"cycleName" : "floracion", "numRelays" : [1]}]
            },
        "powerOn" : {
            "subCycles" : [{"mode" : true, "seconds" : null}]
            },
        "powerOff" : {
            "subCycles" : [{"mode" : true, "seconds" : null}]
            }
    },
    "numRelays" : [1,2,3
}

Once installed, execute as root: sh /etc/init.d/gpirelays.sh {option} OPTIONS:

• start: To start the daemon
• stop: To stop the daemon
• restart: To restart the daemon
• run {cycleName}: To run a cycle. The cycle name is in the configuration file config.json

Example of use:

sudo sh /etc/init.d/gpirelays.sh run test
