@PeteKnight was and still is my best teacher

@Blynk_Coeur you can take a look HERE how I learned it, there is nice examples

@PeteKnight

thanks

PeteKnight · July 18, 2019, 11:43am

I never tried to actually capture the return request value. I just use it for “Alexa, what’s the living room temperature” and hear what Alexa has to say in reply.

Pete.

Ze_Pico · July 19, 2019, 2:18am

@PeteKnight

I found the missing command #7 (“GetTargetTemperatureRequest”)

Command : " Alexa, What is Nest Set To ? "
Alexa answer : " The A/C is Set to 23.5 "

here is the “Process Alexa Responses” function … you can try it.

if (msg.command === "TurnOnRequest"){
    msg.payload = true;
    flow.set('away', false);
    return msg;
}

if (msg.command === "TurnOffRequest"){
    msg.payload = true;
    flow.set('away', true);
    return msg;
}

if (msg.command === "SetTargetTemperatureRequest"){
    if (msg.payload < 10 || msg.payload > 30) {
        var range = {
            min: 10.0,
            max: 30.0
        }
        msg.payload = false;
        msg.extra = range;
    } 
    else {
	    msg.extra = {
		    targetTemperature: {
			    value: msg.payload
            },
            temperatureMode: {
                value: "COOL",
                freindlyName: "YORK"
            }
        } 
     msg.payload = true;
    }
    return msg;
}

if (msg.command === "IncrementTargetTemperatureRequest"){
    T = flow.get('TempTarget');
    t = parseFloat(T);
    T = flow.set('TempTarget', t + 1);
    msg.extra = {
        targetTemperature: {
            "value": t + 1
        }
    };
    msg.payload = true;
    return msg; 
}
   
if (msg.command === "DecrementTargetTemperatureRequest"){
    T = flow.get('TempTarget');
    t = parseFloat(T);
    T = flow.set('TempTarget', t - 1);
    msg.extra = {
        targetTemperature: {
            "value": t - 1
        }
    };
    msg.payload = true;
    return msg; 
}
   
if (msg.command === "GetTemperatureReadingRequest"){
    x =flow.get('TempAmbient');
    msg.extra = {
        "temperatureReading": {
            "value": x},
        "applianceResponseTimestamp": new Date().toISOString()
    };
    msg.payload = true;
    return msg;
}

if (msg.command === "GetTargetTemperatureRequest"){
    y =flow.get('TempTarget');
    msg.extra = {
        targetTemperature: {
            value: y
        },
        temperatureMode: {
        value: "COOL"
        }
    };   
    msg.payload = true;
    return msg;
}

you don’t need a Flow to test just change the x , y and t with numbers and you will get the response.

Safety Rules for My Smart Thermostat (Tasmota Console)

Rule1
if any problem arise with the temperature Sensor, HVAC will shut down [power3],
only one Fan speed is accepted at a time [power4 , power5, power6],
also mode relays “Heating & Cooling” cannot be On at the same time [power1, power2] .

Rule1
on tele-SI7021#temperature=null do backlog Power1 off; Power2 off; Power3 off; Power4 off; Power5 off; Power6 off endon
on Power3#state=0 do backlog Power1 off; Power2 off; Power4 off; Power5 off; Power6 off endon
on power4#state=1 do backlog power5 off; power6 off endon
on power5#state=1 do backlog power4 off; power6 off endon
on power6#state=1 do backlog power4 off; power5 off endon
on power1#state=1 do power2 off endon
on power2#state=1 do power1 off endon

Rule2
if the SI7021 temperature sensor is faulty then publish an MQTT message to turn the power OFF.

Rule2
on tele-SI7021#temperature=null do publish YORK/power off endon

WLED_RGB_ALEXA_EFFECTS

WLED_RGB_ALEXA_EFFECTS: this uses the “node-red-contrib-alexa-local” Alexa-Local node to communicate to Alexa. NO extra Alexa Skills required and NO account linking required to use this node. How this work is you place the Alexa-Local in your flow and give it a name, then tell alexa to search for new devices. once she finds them they are treated as lights. then you just say “Alexa Preset 1 on” or “Alexa turn on Preset 1”. The first 3 nodes in this flow also have extra nodes called “Solid”, “Halloween”, and “Christmas”. I have set the presets in WLED to be the 3 previously named presets and so you can then say “Alexa Christmas Lights on” or “Alexa Turn on Solid Lights” or “Alexa Solid Lights on”. you can change them all to named devices or leave them at “Preset 1” and so on.

Bon travail !
Il va vraiment falloir que j’apprenne a programmer avec Node-Red
Çà m’a l’air bien compliqué

Ze_Pico · October 31, 2019, 11:09am

@Blynk_Coeur
non ce n’est pas complique. mois j’ai 65 ans et j’ apprends toujours.
DrZzs est un (Dr.) Anesthesiste avec 6 enfants et malgre ca il apprend H.A. et l’electronique.
Un peu de volonte et ca marchera.
j’amerais aussi que tu prennes un coup d’oeil sur “Home Assistant” Paradis Artificiels

Home Assistant - HACS - Home Assistant Community Store - Custom UI - Lovelace - Domotique

excuse-moi mon KB est anglais

It’s not that complicated, just a little bit different.
It’s actually very easy to get started, just drag some nodes onto the screen ad join them up with bits of spaghetti and you’ll get some instant results.
But, it’s a bit like Blynk where you very quickly start delving a bit deeper and writing functions - but the language is very similar to C++ so easy to figure out.

For me, Node-Red is a sort of integration layer that makes it very easy for lots of things to talk to each other. all my devices talk to Node-Red using MQTT messages and Node-Red talks to Blynk, Alexa and anything else I want using plug-ins that have already been developed.

You should give it a try.

Pete.

Génial ce site !! merci !

All your SONOFF devices now can be controlled with BLYNK app.

Ze_Pico · March 10, 2020, 7:27pm

if you are using ALEXA or GOOGLE Home , Here is the Flow

the Functions

if (msg.payload.state == "off") {msg.payload = 0} 
if (msg.payload.state == "on") {msg.payload = 1}
return msg;

if (msg.payload.params.switch == 'off' ) {
    msg.payload = 0 ;
    }
    else if (msg.payload.params.switch == 'on') {
        msg.payload = 1 ;
    }
return msg;

@Blynk_Coeur

a good tutorial
