Weather Station with Scene Activator!!!

[BulldogLowell]

@korttoma

thanks for the feedback.

I found that it needed debouncing. It was getting into a funny state once in a while where it would lock up. it was so easy for me to add the capacitor on my breadboard, so I did it. A software debounce with a timeout on the button press would work too.

I started with the sketch that had the radio sleep, never sure if I was going to make it battery version or not, so it was left in. It can be yanked out, do you want to try that?

I really wanted to do two things, get data in, and push data out. I am working on a project that is reliant on both of those so building this was a major step for me.

I thought it had a nice practical use given the display and the scene trigger. Plus it is so easy to build, I thought i could get some more people to look at it and help make improvements.

I'm not a software guy, as you can tell from the sketch...

[BulldogLowell]

@hek

Cool addition the youtube videos right on the MySensors page... nice improvement.

[BulldogLowell]

@korttoma

FYI I added the debounce to the sketch. Even with the cap I had a few lockups. I noticed I could get multiples and needed it to go away.

[BulldogLowell]

I thought I would post a few photos of the finished device. While I like all things tech, my wife does not. So you can see, I have added to the list of making 'stuff' have a purpose.

[korttoma]

Hay @BulldogLowell , I'm trying to make use of your sketch for my own project but I ran in to some issue.

I had trouble finding the right library. I used the "LiquidCrystal_V1.2.1.zip" from here -> https://bitbucket.org/fmalpartida/new-liquidcrystal/downloads

But I got some errors when compiling sketch. Then I found the library link under the ebay item you referred to and now it seems to work.
you could mention this in the first post if possible so others don't fall in the same ditch.

cheers ;)

[korttoma]

Now I ran int to the next issue. How do I know which pin the SDA and SCL should be connected to??

Is it this line that defines it?

LiquidCrystal_I2C lcd(0x27,20,4);

So what should it be if I'm using a Pro Mini?

[korttoma]

I think I found it now... For the Pro Mini it is like this:

"I2C: A4 (SDA) and A5 (SCL). Support I2C (TWI) communication using the Wire library."

I was expecting it to be declared somehow in the sketch so I got confused... Well I learned something once again...

[BulldogLowell]

@korttoma hey, glad you have it figured out.

I have been very busy and haven't been able to check in here for a while:(

all working now?

[korttoma]

Yepp, all working now. Just need to find some time to make my deviec

[korttoma]

Hi @BulldogLowell (or anybody else),I'm hoping you could help me with one last thing to finish this project of mine.

The issue I'm facing is that I do not know how to send a "string" from Vera using luup. Or basically collecting a string from a variable of one device and sending it to a MySensors node. Here is what I tried:

local text = luup.variable_get("urn:empuk-net:serviceId:SimpleAlarm1","StatusLabel", 319)

luup.call_action("urn:upnp-arduino-cc:serviceId:arduino1", "SendCommand", {radioId="11;3", variableId="VAR_3", value=text}, 276)

If I give the variable "text" a numeric value it is sent and received without problems but how the h**l can I send a string??

Grateful for any help

[korttoma]

One step closer:

local text = "Test"

luup.call_action("urn:upnp-arduino-cc:serviceId:arduino1", "SendCommand", {radioId="11;3", variableId="VAR_3", value=text}, 276)

Instantly prints the text "Test" on my display :D
Seems like my issue is that I can not get the text from the SimpleAlarm Variable "StatusLable".

any suggestions?

[korttoma]

Solved! :D

local status_label = luup.variable_get("urn:upnp-empuk-net:serviceId:SimpleAlarm1", "StatusLabel", 319)
luup.call_action("urn:upnp-arduino-cc:serviceId:arduino1", "SendCommand", {radioId="11;3", variableId="VAR_3", value=status_label}, 276)

Found my answere from the vera forum:

Hye korttoma,

Did you finish this project?

I have a bit of time and thought I would convert my weather station up to the new mySensors version... was wondering if you could share your work...

[korttoma]

@BulldogLowell

Hi Jim, Yeah I finished it. there is a few posts about it over in heks scene controller thread -> http://forum.mysensors.org/topic/446/scene-controller

[BulldogLowell]

Tomas,

My business has kept me away from this, I guess I didn't notice how far along you took it... brilliant job!

I'll check in when it's done.

Thanks mate.

Tomas,

Again, thanks for your example. I have to say, it helped a lot.

I am however struggling with radio communication it seems and I am wondering at this point what I am doing wrong, having spent a couple hours trying to find my errors.

[BulldogLowell]

I added delays in the lua code and that seemed to help a lot:

local temp = luup.variable_get("urn:upnp-org:serviceId:TemperatureSensor1","CurrentTemperature", 60)
luup.call_action("urn:upnp-arduino-cc:serviceId:arduino1", "SendCommand", {radioId="11;3", variableId="VAR_1", value=temp}, 85)

luup.sleep(750)

local humid = luup.variable_get("urn:micasaverde-com:serviceId:HumiditySensor1","CurrentLevel", 63)
luup.call_action("urn:upnp-arduino-cc:serviceId:arduino1", "SendCommand", {radioId="11;3", variableId="VAR_2", value=humid}, 85)

luup.sleep(750)

local low = luup.variable_get("urn:upnp-org:serviceId:TemperatureSensor1","CurrentTemperature", 61)
luup.call_action("urn:upnp-arduino-cc:serviceId:arduino1", "SendCommand", {radioId="11;3", variableId="VAR_3", value=low}, 85)

luup.sleep(750)

local high = luup.variable_get("urn:upnp-org:serviceId:TemperatureSensor1","CurrentTemperature", 62)
luup.call_action("urn:upnp-arduino-cc:serviceId:arduino1", "SendCommand", {radioId="11;3", variableId="VAR_4", value=high}, 85)

luup.sleep(750)

local conditions = luup.variable_get("urn:upnp-org:serviceId:Weather1","CurrentTemperature", 59)
luup.call_action("urn:upnp-arduino-cc:serviceId:arduino1", "SendCommand", {radioId="11;3", variableId="VAR_5", value=conditions}, 85)

still struggling with this, however:

if (message.type == V_VAR5)
{
  conditions = String(message.data);
  DEBUG_PRINT(F("Received today's Conditions:"));
  DEBUG_PRINTLN(conditions);
}

not returning the present conditions....

[BulldogLowell]

also noticed that variable5 (V_VAR5) does not show up here (in device 85):

[korttoma]

@BulldogLowell

I do have all 5 variables listed under my scene-controler device. Do you still get the failed for getting time in your serial print? Seems like you might have "general" communication issues, you have cap on the radio? Try a different power source or temporarily move your device closer to the gateway. I had some similar problems when trying to use the PA+LNA radio module so I switched to a regular one and that one works fine. I wanted to use the PA+LNA version because the device is quite far from GW and I did not think the regular one could handle the distance but it did.

Thanks for showing me how to add a delay to the lua code btw, I newer figured that out so I only ewer sent two variables at a time. Btw, does the delay affect vera in any way? I thought I read somewhere that the unit does not do anything during sleep.

[BulldogLowell]

Tomas,

(and I'm opening this up to anyone who knows how to work messages into more than one device )

well, I figured out the problem of "conditions" which was the wrong serviceId in the lua coding for that variable.

Regarding the delay, if you luup.sleep() for anything that approaches a second, your Vera will restart :( so I figure that the 750ms would be OK. I am concerned about it being incommunicado so often, so I'll probably put the transmissions into different scenes.

I definitely have a communication issue... and it bothers me a bit. I have all that, capacitors on the antenna, etc. I think I have a bad node and its likely my PhoneyTV. Whenever I 'manually' toggle the lights using the Vera interface, it seems to lock up the gateway.... More on that to come.

I really appreciate your sharing the code. In retrospect, it seems that the latest mySensors implementation is a lot more elegant with respect to setting up communications like these, but the example helped immensely.

I'm now tripping up on using variables in the second device: Can I recycle the variables here (e.g. V_VAR1) or must I create another instance of gw?

MySensor gw;
DHT dht;
//
MyMessage msgOn(CHILD_ID_SCENE, V_SCENE_ON);
MyMessage msgOff(CHILD_ID_SCENE, V_SCENE_OFF);
MyMessage msgVAR1(CHILD_ID_SCENE, V_VAR1);// outdoor temperature
MyMessage msgVAR2(CHILD_ID_SCENE, V_VAR2);// outdoor humidity
MyMessage msgVAR3(CHILD_ID_SCENE, V_VAR3);//today's low
MyMessage msgVAR4(CHILD_ID_SCENE, V_VAR4);// today's high
MyMessage msgVAR5(CHILD_ID_SCENE, V_VAR5);//conditions
//
MyMessage lightMsg(CHILD_ID_LED, V_LIGHT);
//MyMessage msgMOTD(CHILD_ID_LED, V_VAR1); // message of the day//<<<<<<<<<<<<<<<<<
//MyMessage msgAlarm(CHILD_ID_LED, V_VAR2); // alarm status//<<<<<<<<<<<<<<<<<<<<<<<<
//MyMessage msgBrite(CHILD_ID_LED, V_VAR3); // led briteness (nice idea!!!!)<<<<<<<<<<<<<<<
//

setup() bit:

   //
  dht.setup(HUMIDITY_SENSOR_DIGITAL_PIN);
  gw.begin(getVariables, RADIO_ID);
  gw.sendSketchInfo("WeatherClock", "1.0");
  gw.present(CHILD_ID_SCENE, S_SCENE_CONTROLLER);
  gw.present( CHILD_ID_LED, S_LIGHT);
  int clockTimer;

used here:

void getVariables(const MyMessage &message)
{  
  if (message.type == V_VAR1)
  {
    OutdoorTemp = atoi(message.data);
    DEBUG_PRINTLN(F("OutdoorTemp recieved:"));
    DEBUG_PRINTLN(OutdoorTemp);
  }
  if (message.type == V_VAR2)
  {
    OutdoorHumidity = atoi(message.data);
    DEBUG_PRINT(F("OutdoorHumidity recieved:"));
    DEBUG_PRINTLN(OutdoorHumidity);
   }
   if (message.type == V_VAR3)
  etc...

any advice?

best,

Jim
