Using Hogarama - Gepardec/Hogarama GitHub Wiki

This page describes how to use Hogarama to care for your plants.

Configure the watering strategy

Whenever a sensor value is sent to the server, the watering component uses the following algorithm:

1. Compute the average sensor value for a sensor with name sensorName during the last measureInterval minutes
2. If the result is lower than lowWater, activate the actor (pump) with name actorName for waterDuration seconds.

The default for these values (for the sensor with name GruenerGepard) is:

"sensorName" : "GruenerGepard",                                                                                                                                                                  
"actorName" : "GruenerGepard",                                                                                                                                                            
"measureInterval" : 1,                                                                                                                                                                    
"lowWater" : 0.2,                                                                                                                                                                         
"waterDuration" : 5                                                                                                                                                                       

As for now there is no GUI tho change these values. If you want to change the values, do the following:

Login-to-mongodb

On the MongoDB prompt view the wateringConfig collection:

> db.wateringConfig.find({}).pretty()

or

        "className" : "com.gepardec.hogarama.domain.watering.WateringConfigData",

        "measureInterval" : 1,                                                                                                                                                                    
        "lowWater" : 0.2,                                                                                                                                                                         
        "waterDuration" : 5                                                                                                                                                                       
}

Then change for example the lowWater to 0.4. For this you may prepare a db.wateringConfig.update(...) command in an editor and paste it into the terminal. Command:

db.wateringConfig.update(
   { "_id" : "GruenerGepard" },
{                                                                                                                                                                                                 
        "_id" : "GruenerGepard",                                                                                                                                                                  
        "className" : "com.gepardec.hogarama.domain.watering.WateringConfigData",
