Read outdoor temperature with alexa

General
1

good morning,
i use NodeRED3.0.2 on docker
i installed node-red-contrib-alexa-cakebaked
i have mosquitto and domoticz

How do I make an alexa logger, that is, make alexa upon receiving the word 'external', activate the (working) procedure below?

To do this you need to either create a "virtual" thermostat device, or make use of the Q&A Skill, so that Alexa knows what you are asking it for.

I see your flow comes from this post trying-to-get-alexa-to-read-out-a-temperature

Did you read it all ?

It provides solutions and also links to another thread about the Q&A skill pure-fun-with-alexa-and-alexa-skills

ok thanks for the info. i solved it with the directions in this post Trying to get Alexa to read out a temperature - #41 by dynamicdave . Basically , it reads the mqtt info from the sensor, turns it into a voice command for alexa which announces it from echo device you are querying it from. I would also like to make it work from smartphone but I am not able to do that.

5

I have this problem ie, when the temperature is below zero , alexa does not read the

indication - (ex: -3.3grades) I think there is some problem in the function node:

// Get the flow variable(s) to be used in the message
var temperature = flow.get("temperature") || 0;

// Convert them to a string
temperature = temperature.toString();

//whisper message
var k, l;
if (msg.payload.Quiet == "On") {
  k = '   <amazon:effect name="whispered">'
  l = '   </amazon:effect>'
}
else {
  k = ""
  l = ""
}

var message = k+"la temperatura esterna è di <break time='0.5s'/>"+ temperature + "gradi celsius <break time='0.25s'/>"+l;


msg.payload = message;
return msg;

the debug output is correct and reports the minus sign but alexa does not pronounce it .

payload: "la temperatura esterna è di <break time='0.5s'/>-2.7gradi celsius <break time='0.25s'/>"
_msgid: "dd4492cd56ff7d98"
6

Does it need the word rather than the symbol?

8

in the way I wrote above the temperature announced by alexa is always positive, this morning for example we were the thermometer read -5 degrees but alexa announced 5 degrees above zero. I tried to write just so: var message = temperature ; and alexa correctly announces the temperature.
Of course , I would also like it to announce all the part of the message "the temperature is of " but it doesn't seem to work adding it.

9

Just tried this out and can agree with you it ignores 'saying' the minus.

If you insert a 'space' after temperature and before " gradi celsius........"
I think you will find it works correctly and says the word 'minus'.

I've modified the statement at the top of this post, so you can cut-n-paste it in to your code.

Please let me know if it works for you?

thanks dave ; i modified as you said so it seems to work:

var temperature = flow.get("temperature") || 0;
temperature = temperature.toString();

var a = " la temperatura esterna è di <break time='0.1s'/>";
var b = " gradi celsius <break time='0.25s'/>";

//whisper message
var k, l;
if (msg.payload.Quiet == "On") {
    k = '   <amazon:effect name="whispered">'
    l = '   </amazon:effect>'
}
else {
    k = ""
    l = ""
}

var message = k+a+temperature+b+l;
msg.payload = message;
return msg;

here we are below zero and now alexa announces the temperature correctly !! :muscle:

To read the daily power consumption always with a flow similar to the one above I had to round the today variable like this below.

Function 
var today = flow.get("today") || 0;

var today = (today).toFixed(2);

today = today.toString();

var message = " i consumi giornalieri sono di <break time='0.5s'/> "+ today + " kilovattora <break time='0.25s'/> ";

msg.payload = message;
return msg;

This is because if alexa is given a variable with three decimal places it announces a number without the decimal point (ex: 5.436----> 5436) .It seems to work ,I would like to find information about it.

13

I'm continuing to refine the flow of external temperatures of Dave, I made alarm flow, which based on a certain temperature sends a voice alert with alexa and a telegram message, it all works. But I have an annoying effect, that is timing the 'iniect every 2 seconds, when I do a deploy or reboot the raspberry triggers the alarm; I've seen examples that use link in and link out but how can I use it if I'm using input values taken via MQTT ?
