Good afternoon everyone,
i'm looking for a little help have already tried several things but can't figure it out.
if I use my slider to adjust the temperature, I get the data neatly, if I then want to send the actual temperature an error message appears ... what am I doing wrong
there is a lot of talk about float and found the following about it
i = msg.payload;
v = i. toFixed(2);
msg.payload = '{"tempjas": ' + v + '}';
return msg;
Number.prototype.toFixed() - JavaScript | MDN (mozilla.org)
toFixed needs a number, you've probably passed a string. Check with a debug output or put a statement like node.warn(typeof msg.payload) in your function node.
Also, why are you creating a string that looks like JSON? Why not just create a javascript object?
Finally, please post code to the forum as a code block not as text as that is hard to read and cannot always be copied if someone wants to test it.
It's my first post sorry
I should have placed the code correctly now
it is indeed a string
and Java, Fine it's about the end result

I turned it into java and indeed more is coming out

Hi Robert,
I use the EasyIO Controllers also but i havent tried their MQTT capabilities yet.
When you post on the forum use this icon
so your flow and code will be correctly formatted
Use the pencil icon 
to re-edit your post and correct it .. otherwise we cannot import it.
I know nothing about your system but regarding your MQTT topics - never start or end a topic with a / While a leading slash will work, it is simply not recommended as it just creates an empty 1st level topic. As for trailing slash, this would create an empty subtopic (probably doesnt play nice on some brokers)
In simple terms, change your topic to wens/tempjas
Thank you very much man,
EasyIO is the best controller out there right now for this money
I am a supplier in NL
Thanks for the explanation, I am not too handy with forums yet
thanks as far as I can see the data about MQTT is neat but my EasyIO controller does not handle this yet
I just have to look a little further
good afternoon
I am still puzzling
I have as you indicated adjusted the topic and a yaml in between but still get no result

Hi, as you provide no sample data for domoticz/# i have no idea what is supposed to be happening.
In the 2nd function, you do this...
msg.payload = { "wens/tempjas" : msg.payload };
return msg
you should do this...
//msg.payload = //<<< no need to set payload, you did that in function 1
msg.topic = "wens/tempjas"; //<< Set the topic of the msg.
return msg
... or use a change node to set topic (see my demo flow below)
Are you REALLY wanting to send YAML formatted data to MQTT? I suspect NOT - just delete it and let the topic + payload be sent

Yes .. they are amazing .. especially the new FS32 & FS20 series are a great improvement to speed .. many inputs outputs and the way they are programmed is very easy .. wiring pieces of logic together like in Node-red .. the concept is quite revolutionary. Of course it doesnt come close to NRs capabilities in programming 
May i add .. like in this case that we dont have your MQTT in node, we dont know what msgs come out of it ... you can capture a few messages by adding a Debug node after it and set it to
and from the Debug window use the Copy value icon to copy the 'root' of the msg in order to post on the forum.
Im sure if you follow Steve's suggestions you'll have it working.
Good afternoon everyone,
IT WORKED
with a small adjustment
thank you very much for the support
