I try to create a node with 7 condition if all condition it activate my blower, if it not it turn off...
The blower take hot air in my basement fire place(sensor1), and transfer it in my living-room(sensor2)
My others condition are slider in my lovelace who let my choose the temp Min(3) end Max(4) of my basement, and the temp we will reach in te living-room (5). I have also had a adjustable tolerance (6) to limit the trigger, and a Automation on/off(7).
My Input are group in a Joint node and output are set up, but I have trouble to figure how to set up function...
What I try to do is
IF switch (7) is ON
AND my temp (sensor1) is between the preset temp (3) and (4) (+/- tolerance (6))
AND my temp (sensor2) is lower then the preset temp (5) (+/- tolerance (6))
Then start my blower
Hard to say for sure as i dont know your variable names and msg structure, You need to add a output from a debug, after the node that creates your msg.
The structure of such a if statement would be something like below.
if (switch7 === "ON" &&
mytempsensor1 > (temp3 - tolerance) &&
mytempsensor1 < (temp4 + tolerance) &&
mytempsensor2 < (temp5 - tolerance) ) {
// do somthing when true
msg.payload = true;
}else{
// do something when false
msg.payload = false;
}
return msg;
I try to adapt to my need, could you see what I do wrong?
I always have false at the top exit instead true or nothing, and nothing on the bottom exit...
if ("input_boolean.souffleur_automatique" === "1" &&
"multi_sensor1/sensor/temperature_coin_a_bois/state" > ("input_number.temperature_poele_min" - "input_number.temperature_tolerence") &&
"multi_sensor1/sensor/temperature_coin_a_bois/state" < ("input_number.temperature_poele" + "input_number.temperature_tolerence") &&
"cam3/sensor/garage_temperature/state" < ("input_number.temperature_salon" - "input_number.temperature_tolerence") ) {
// do somthing when true
msg.payload = true;
return (msg, null );
}else{
// do something when false
msg.payload = false;
}
return (null, msg );
Correct will be return [null, msg]
I can not help with images. If you want more help create a test flow, consisting of an inject with object set in msg.payload , a function node with your code and a debug node. Then we will have the info to help.
Sorry, I am a new user of node red maybe 6-7 days, what is a test flow?
A shorter version of your flow with less junk.
an inject containing the debug output from after the join node. In the debug window to the right of the object name , when you hoover mouse you get options , one is to copy value. you can then paste that value in the inject node and select json.
a copy of your function node.
and a debug/s nodes to show values.
select the nodes by holding Ctrl and selecting them with the mouse. Then press Ctrl/e and copy text.
Then paste text here by pressing </> aat top of reply window, and pasting the code between the backticks, like below.
```
code
```
Looking here the values are in msg.payload.
so add msg.payload to the front of all your variables.
Input
input_number.temperature_tolerence : msg.payload : Object
object
multi_sensor1/sensor/temperature_coin_a_bois/state: 46
cam3/sensor/garage_temperature/state: 26
input_number.souffleur_automatique: 1
input_number.temperature_poele: 65
input_number.temperature_poele_min: 24.5
input_number.temperature_salon: 25
input_number.temperature_tolerence: 1
function
if ("input_boolean.souffleur_automatique" === "1" &&
"multi_sensor1/sensor/temperature_coin_a_bois/state" > ("input_number.temperature_poele_min" - "input_number.temperature_tolerence") &&
"multi_sensor1/sensor/temperature_coin_a_bois/state" < ("input_number.temperature_poele" + "input_number.temperature_tolerence") &&
"cam3/sensor/garage_temperature/state" < ("input_number.temperature_salon" - "input_number.temperature_tolerence") ) {
// do somthing when true
msg.payload = true;
return (msg, null);
}else{
// do something when false
msg.payload = false;
}
return (null, msg);
I still do not have a copy of the object, that i can just copy and paste. If you copy value correctly using copy value icon to right of msg.payload, then i can work with it, but what you have pasted is not a valid json.

Ok and what is wrong?
This is not a test flow and does not contain any functon or inject node
This is an example of a correctly formated json notice the { } and the " " and the :
{"topic":"Mypi/2/KW","payload":{"KW_Total":434},"qos":0,"retain":false,"_msgid":"ef0287b6.34ca08"}
if you look at image you can see my cursor over the copy value icon.

you will see i put the json in the inject node for testing
if you create a json that should return true in a seperate inject node you can the test the function.
edit/ changed === "1" to === 1
Before that change, always false at te bottom output
After remove " " I have nothing at the output...
I saw your input are set to string, mine are set to number, it is made a difference?
