Temperature Controlled Lights - Need a little help for a newbie

[lancebooth]

I would like to control the lights around my house according to the temperature. I live in the south of the US and when it gets close to freezing I would like to turn on Christmas lights to ward off the somewhat colder temperatures...

I wrote a new program (borrowing heavily, well exclusively, from the HG application) and, I can apply it to a specific module or modules that apply by name, I cannot figure out how to apply it to all of the modules in a group, with out their names...

PROGRAM CODE:

Code: [Select]

int onTemp = int.Parse (Program.Option("onTemp").Value);
int offTemp = int.Parse (Program.Option("offTemp").Value);
string onCondition = (Program.Option ("onCondition").Value);

// Modules.InGroup(PROGRAM_OPTIONS_STRING).OfDeviceType("Light,Dimmer,Switch").Each (mod => {

int temperature_f = int.Parse (Program.WithName("Weather Underground").Parameter("Conditions.TemperatureF").Value);

var light = Modules.WithName("Outside Front");

if (onCondition == "TRUE") {
if (temperature_f < onTemp) {
light.On();
} else if (temperature_f > offTemp) {
light.Off();
}
} else {
if (temperature_f > onTemp) {
light.On();
} else if (temperature_f < offTemp) {
light.Off();
}
}

light = Modules.WithName("Citrus Tree Lights");

if (onCondition == "TRUE") {
if (temperature_f < onTemp) {
light.On();
} else if (temperature_f > offTemp) {
light.Off();
}
} else {
if (temperature_f > onTemp) {
light.On();
} else if (temperature_f < offTemp) {
light.Off();
}
}
//});


TRIGGER CODE:

Code: [Select]

// this Setup delegate will be executed once, when program become active
Program.Setup(()=>{

  // set input fields parameters
  // <field_name>, <default_value>, <description>
  // Program.AddOption(<field>, <defaultValue>, <description>, <type>)
  Program.AddOption("offTemp", "42", "The temperature to turn off the lights.", "int");
  Program.AddOption("onTemp", "38", "Temperature to turn on the lights", "int");
  Program.AddOption("onCondition", "TRUE", "For instance: to keep lights from flickering TRUE if lights come 'ON' < 38 and 'OFF' > 42", "bool");

});
//
return true; // execute "Code To Run"

The easiest way is to use InGroup and OfDeviceType. You were on the right track, only the implementation needed to be slightly defferent.

Code: [Select]

var lights = Modules.InGroup("Outside Lights").OfDeviceType("Light,Dimmer,Switch");

if (onCondition == "TRUE") {
   if (temperature_f < onTemp) {
      lights.On();
   } else if (temperature_f > offTemp) {
      lights.Off();
   }
} else {
   if (temperature_f > onTemp) {
      lights.On();
   } else if (temperature_f < offTemp) {
      lights.Off();
   }
}

Wonder its worth having a code snippets section in the app contributions bit on github??

[lancebooth]

Works like a charm!

An app contributions section on github probably would have helped me... I went through the documentation on the HomeGenie site, and was having trouble finding sample code to help me, which is why I posted here...

I do have one further question... Is there a way to dynamically get the group name instead of hard-coding it? I would like to be able to add the module to a group and have it control the lights without having to use a specific group name.

Thankyou very much for your help.

If you want to switch all lights on and off manually you can use the 'All lights on' and 'All lights off' programs (Programs -> Scenes).

The code is quite simple, maybe something like the following will work to automate it: (This looks a little bit like your original code)

Code: [Select]

var lights = Modules.InGroup(PROGRAM_OPTIONS_STRING).OfDeviceType("Light,Dimmer,Switch");

if (onCondition == "TRUE") {
   if (temperature_f < onTemp) {
      lights.On();
   } else if (temperature_f > offTemp) {
      lights.Off();
   }
} else {
   if (temperature_f > onTemp) {
      lights.On();
   } else if (temperature_f < offTemp) {
      lights.Off();
   }
}

And then add the program to the correct group via Configure -> Groups


Edit: You might have seen this already, but there are som good examples here:

Thank you for responding...

I actually saw the PROGRAM_OPTIONS_STRING but being an old C (not C++) programmer, it looked like a constant to me... I didn't realize it was set dynamically.

I will test it in the morning, since (unusual for this time of year) it is already freezing here and I fear my fruit trees will suffer (and thus the citrus fruit) if I have to test it too much. :-)
