Weather Station with Scene Activator!!!

@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.

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

[korttoma]

Did not try it but how about this:

void getVariables(const MyMessage &message)
    {
        if (message.sensor==CHILD_ID_SCENE){  
            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...

        if (message.sensor==CHILD_ID_LED){  
            if (message.type == V_VAR1){
                DayMessage = atoi(message.data);
                DEBUG_PRINTLN(DayMessage);
           }
           if (message.type == V_VAR2){
               AlarmStatus = atoi(message.data);
               DEBUG_PRINT(F("House is:"));
               DEBUG_PRINTLN(AlarmStatus);
          }
          if (message.type == V_VAR3)
             etc...

@korttoma

thanks, I'll give it a shot.

another method for dispatching messages (with delays in between) from Vera with this type of lua function:

(thanks to @RexBeckett for the assistance)

function SendWeatherData(strstep)
	local step = tonumber(strstep)
	if step == 1 then
		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)
	elseif step == 2 then
		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)
	elseif step == 3 then
		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)
	elseif step == 4 then
		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)
	elseif step == 5 then
		local conditions = luup.variable_get("urn:upnp-micasaverde-com:serviceId:Weather1","Condition", 59)
		luup.call_action("urn:upnp-arduino-cc:serviceId:arduino1", "SendCommand", {radioId="11;3", variableId="VAR_5", value=conditions}, 85)
	end
	step = step + 1
	if step <= 5 then
		luup.call_delay(1,tostring(step))
	end
end

SendWeatherData("1")

[korttoma]

wow, don't understand what that lua function does but I'll give it a try. Thanks @RexBeckett

[BulldogLowell]

@korttoma

"The following code calls the function SendWeatherData immediately and the function calls itself with a one second delay. Each time the function runs, it uses a step counter to chose a value to be read and sent. The step gets incremented on each run until it exceeds five after which the function stops calling itself." - rex

This way, it shouldn't affect vera's watchdog.

Rex is really helpful on matters of lua ;)

[BulldogLowell]

@korttoma

I was thinking that perhaps it may be easier/better to recycle V_VAR1 and transmit messages to the node with a leading char. then have the arduino sort out the message based on the header:

for example:

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

then sort and strip out the char arduino-side... you could move a lot more message types through one variable

new message types need to be hard coded into Arduino and Vera, so if we want to expand the data flow... it becomes easier this way, no? Perhaps there is a better message type to use for this type of effort...

This device is in our guest house and since I have it open I want to add capabilities like:

1: Message of the day
2: quick SMS type of message
3: alarm clock settable by mobile app
4: twitter feed

stuff like that...

Nice job on the sketch Jim, I especially liked the idea with "#define DEBUG". There were allso some other ideas I will be stealing some day when I find time to update my sketch.

So I guess you did not use the function by @RexBeckett then? I could not get it to work either. I'll try your suggestion with the delays.

[BulldogLowell]

@korttoma

Thanks for your help and time, you made it a lot easier! I'm trying to write the code for an audience rather than myself so I'm focused more on what I'm putting into the sketch versus just 'getting it to work.' I'm going to get that led dimming next!

I messed around with the function but lost patience with it,,. I'll get my lua book out and tackle that one rainy day. Meanwhile, I have been using these delays without any issues (no Vera re-starts) and can probably work on shortening the delay times now that I have my Ethernet gateway working so well!!!

best network performance ever for me since I started with MySensors :)

I keep looking at your scene controller (and the one Henrik did) and I guess I just have to pick one to make!!

[korttoma]

It was all my pleasure Jim, it is nice to have someone to exchange ideas with. I take it you mean the dimming of the backlight right? Let me know if you need some details.

I have also put together a Ethernet GW some time ago but newer got around to take it in to use. And then there was all this about the SPI issue so I guess I need to take it on again at some point. A bit unclear if it will work with the Ethernet board I have anyway.

yeah, I meant dimming the LED backlight, a nice touch to your project.

your ethernet board uses the same Wiznet chipset, so you may want to try what was posted on the other thread. I got frustrated with my Serial gateway losing its communication with Vera.

Hello, I am building this same thing and have used the sketch and luup code above thanks to @BulldogLowell & @korttoma!

I am having issues though pulling a variable to send to the lcd screen via luup. I put this device under the Light Variable 4 code is at the bottom of the Lua below. This device is another mysensor that is visible in Vera so I am not sure what is wrong, any help someone could provide would be great.

Luup code:

local temp = luup.variable_get("urn:upnp-org:serviceId:TemperatureSensor1","CurrentTemperature", 7)
luup.call_action("urn:upnp-arduino-cc:serviceId:arduino1", "SendCommand", {radioId="11;3", variableId="VAR_1", value=temp}, 103)
luup.sleep(750)
local humid = luup.variable_get("urn:micasaverde-com:serviceId:HumiditySensor1","CurrentLevel", 10)
luup.call_action("urn:upnp-arduino-cc:serviceId:arduino1", "SendCommand", {radioId="11;3", variableId="VAR_2", value=humid}, 103)
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}, 103)
 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}, 103)
luup.sleep(750)
local conditions = luup.variable_get("urn:upnp-micasaverde-com:serviceId:Weather1","Condition", 6)
luup.call_action("urn:upnp-arduino-cc:serviceId:arduino1", "SendCommand", {radioId="11;3", variableId="VAR_5", value=conditions}, 103)
luup.sleep(750)  
local conditions = luup.variable_get("urn:upnp-micasaverde-com:serviceId:Weather1","Forecast.1.Condition", 59)
luup.call_action("urn:upnp-arduino-cc:serviceId:arduino1", "SendCommand", {radioId="11;4", variableId="VAR_2", value=conditions}, 103)
 luup.sleep(750)
  local conditions = luup.variable_get("urn:upnp-micasaverde-com:serviceId:TemperatureSensor1","CurrentTemperature", 98)
 luup.call_action("urn:upnp-arduino-cc:serviceId:arduino1", "SendCommand", {radioId="11;4", variableId="VAR_4", value=HTTemp}, 103)
  luup.sleep(750)

it looks like you are making a call for the variable "conditions" and passing "HTTemp" in the two last commands. here:

local conditions = luup.variable_get("urn:upnp-micasaverde-com:serviceId:TemperatureSensor1","CurrentTemperature", 98) -- you get "conditions"

luup.call_action("urn:upnp-arduino-cc:serviceId:arduino1", "SendCommand", {radioId="11;4", variableId="VAR_4", value=HTTemp}, 103) -- you set "HTTemp"

luup.sleep(750)

that could be it...

@BulldogLowell I was under the impression that the value could be named what ever you want, is that not the case? changing the value to temp should fix the issue you think?

now I am confused.

You are (it seems to me) retreiving a value from device 98, no?

You are then writing that to device 103, at VAR_4... yes?

please clarify for me.

(reference the snippet of code in my last post)

@BulldogLowell Thanks for pointing that out, I actually need to write VAR4 to device 105. I have made the necessary changes but still isn't working.

 local temp = luup.variable_get("urn:upnp-   org:serviceId:TemperatureSensor1","CurrentTemperature", 7)
 luup.call_action("urn:upnp-arduino-cc:serviceId:arduino1",  "SendCommand", {radioId="11;3", variableId="VAR_1", value=temp}, 103)
luup.sleep(750)
local humid = luup.variable_get("urn:micasaverde-com:serviceId:HumiditySensor1","CurrentLevel", 10)
luup.call_action("urn:upnp-arduino-cc:serviceId:arduino1", "SendCommand", {radioId="11;3", variableId="VAR_2", value=humid}, 103)
 luup.sleep(750)
 local low = luup.variable_get("urn:upnp-org:serviceId:TemperatureSensor1","CurrentTemperature", 8)
 luup.call_action("urn:upnp-arduino-cc:serviceId:arduino1", "SendCommand", {radioId="11;3", variableId="VAR_3", value=low}, 103)
 luup.sleep(750)
 local high = luup.variable_get("urn:upnp-org:serviceId:TemperatureSensor1","CurrentTemperature", 9)
 luup.call_action("urn:upnp-arduino-cc:serviceId:arduino1", "SendCommand", {radioId="11;3", variableId="VAR_4", value=high}, 103)
 luup.sleep(750)
 local conditions = luup.variable_get("urn:upnp-micasaverde-com:serviceId:Weather1","Condition", 6)
 luup.call_action("urn:upnp-arduino-cc:serviceId:arduino1", "SendCommand", {radioId="11;3", variableId="VAR_5", value=conditions}, 103)
 luup.sleep(750)  
 local conditions = luup.variable_get("urn:upnp-micasaverde-com:serviceId:Weather1","Forecast.1.Condition", 6)
 luup.call_action("urn:upnp-arduino-cc:serviceId:arduino1", "SendCommand", {radioId="11;4", variableId="VAR_2", value=conditions}, 105)
  luup.sleep(750)
  local temp = luup.variable_get("urn:upnp-micasaverde-com:serviceId:TemperatureSensor1","CurrentTemperature", 98)
  luup.call_action("urn:upnp-arduino-cc:serviceId:arduino1", "SendCommand", {radioId="11;4", variableId="VAR_4", value=HTTemp}, 105)
  luup.sleep(750)

You are stil not giving HTtemp any value!
