Hello. Im having difficulties converting data i think. node named "juhtimine" does not output numbers as i think it should. I have no previous experiences with javascript. Heres the flow, i hope real programmers understand what i want to do in this flow. [{"id":"417c5761.10e258","type":"tab","labe…

Show the flow where you are now joining the messages.

[image] Ragnarre: not output numbers Hi and welcome. 1st it is necessary that you send screenshots from the output of your debug nodes because we cannot simulate your input (from mqtt) What I can tell you now is all data you receive from mqtt is handled as strings. Mqtt data don`t carry any…

i have been playing around with "join", "change" node and other functions but havent found any solution because i dont really understand why last node dont see these values. complete msg object prints out these values... [ { "id": "b98337a5.8a2928", "type": "function", …

Each msg enters the function node seperate from the other msg's. So when the msg out of the 'temp' function enters the 'justimine' function node, none of the data from the other three functions exist at that time. And when the msg from the 'liliti' function node gets to the 'justimine' function nod…

"temp" will be automatically updated every 30 second in mqtt broker. other mqtt values are retained and will change if manually changed (input from smartphone app). so these other values are lost after each update? what could be solution? i did try to join them with "join" node but i messed up. c…

What you have set in MQTT has no bearing on what happens in the flows (other than it injects messages into the flow. What you should do it attach an inject node where each mqtt node is. This way you will duplicate what is happening but much slower. Even if you had one inject triggering all the path…

You may also want to have 'and after every additional message' checked in the Join node, it depends on your requirement.

In the function in the third column there is something wrong. The objects you create in the return statement is not formatted well return {“a”:a,”b”:b,”c”:c, “temp”:temp} Is perhaps giving you the desired result here. A property inside an object is always defined by the property name as a string, …

plus you are returning that as the msg - not the msg.payload so the debug is configured incorrectly if you want to see the complete message. You should really return {payload: {"a":a, "b":b, "c":c, "temp":temp})

The reason you’re seeing these errors is because your properties contain slashes which are interpreted as divisor rather than part of the name. I saw this same issue explained to someone else a couple days ago, let me dig up the post for you. You can follow the instructions there to get rid of this error, then continue with the next part: following the instructions of those posting above me.
