Good evening @edwin1234,

You said:

It
Works perfectly

I would say, it works (almost).

The svalue is in this case a fixed value of "0", which means "normal" .
See: https://piandmore.wordpress.com/2019/02 ... -domoticz/

lv is the environment level which can have the following values:

0, normal
1, comfortable
2, dry
3, wet

So regardless of the "Humidity" in percent the environmental level is always normal.

About 5 years ago I created a kind of model for all weather sensors, which I recently updated to support newer Node-RED versions:

See: viewtopic.php?p=263147&hilit=weather#p263147 My post 09 Dec 2020, 16:57.
And also: viewtopic.php?p=323593&hilit=weather#p323593 My post 12 Feb 2025, 19:13

If you want to use that function, you should change the code in the "Function" node into the following:

Code: Select all

let hum_stat;

function comfortlevel(hum) {
    
switch (true) {
    case hum > 70: { hum_stat = 3 } break;
    case hum < 30: { hum_stat = 2 } break;
    case hum >= 30 && hum <= 45: { hum_stat = 0 } break;
    case hum > 45 && hum <= 70: { hum_stat = 1 } break;
    default: { hum_stat = 0 } break;
}
return hum_stat;
}

let hu = msg.payload.humidity / 10;
let lv = comfortlevel(hu).toString(); 

msg.payload = { "command": "udevice", "idx": 1234, "nvalue":parseInt(hu), "svalue": lv};

return msg;

Let me know, if this works for you,

Regards

Thanks for your update
Im gonna try this as soon as possible.
And let you know the results .

Hi firewizard,
Can i copy this in to the function node or must i manualy type everything?
Cant find how to do this.

Hi @edwin1234,

I would do it as follows:

1. Drag and drop a new "Function" node to the canvas.
2. Then go to the code block in my previous post and "SELECT ALL".
3. Ctrl-C
4. Open the new "Function" node and
5. Ctrl-V
6. Make your changes, as you did also previously.
7. Replace your old "Function" node with the new one.

Regards

Thanks,
Now i see i have to do it with a laptop, i did it with copy paste on the ipad with the onscreen keyboard then you cant paste it in the function node.

Hi firewizard,
Must it be done like this?

Code: Select all

 let hum_stat;

function comfortlevel(hum) {
    
switch (true) {
    case hum > 70: { hum_stat = 3 } break;
    case hum < 30: { hum_stat = 2 } break;
    case hum >= 30 && hum <= 45: { hum_stat = 0 } break;
    case hum > 45 && hum <= 70: { hum_stat = 1 } break;
    default: { hum_stat = 0 } break;
}
return hum_stat;
}

let hu = msg.payload.data.dps["19"] / 10;
let lv = comfortlevel(hu).toString(); 

msg.payload = { "command": "udevice", "idx": 2381, "nvalue":parseInt(hu), "svalue": lv};

return msg;

Hi @edwin1234,

Must it be done like this?

Yes, that is correct, at least as the data, that you receive in msg.payload.data.dps["19"] is equal to a 3 digit number.e.g. 468, which would result in 46% humidity.

I did it like this
But for some reason it doesnt work?
Now i dont get the info into domoticz while it worked while it was like
This:

Code: Select all

 msg.payload = { "command": "udevice", "idx": 2381, "svalue":"0","nvalue": parseInt (msg.payload.data.dps["19"] / 10)}
return msg;

Can you send me your flow?

Posted: **Saturday 15 March 2025 13:28**

I have send you the flow,
Your function node is not atached for now because it didnt work.
And its a bit a mess, but just for testing.

Posted: **Saturday 15 March 2025 18:01**

Hello @edwin1234,

I compared the contents of the "Function" node with the one in my "Test" flow.

The contents is equal, so no visible difference. For the moment it works for me, and I cannot explain, why it does not work for you.
As a reference I have attached my test flow.. Try this.

Code: Select all

Thanks firewizard
I wil try it out en let you know

For some strange reason its working now.
Dont know how but that doesnt matter

Regards

Posted: **Sunday 16 March 2025 16:49**

Hello @edwin1234,

Good to hear.

It is something strange, I had it also.
When I connected "your Function" node to the same "Inject" node, your "Function" node
did not produce any output, while my original "Function" node (with the same contents) produced the expected output.

I disconnected my "Function" node and it started to work. I reconnected my "Function" node again and
got 2 identical outputs. Strange and I could not reproduce the error afterwards.

Okay, it is working now, so we leave it.

Regards
