Hi, i just want to add these two values:
I changed the topic:
var temp = (msg.payload[1])
msg.payload = temp;
msg.topic = "P1"
return msg;
but no matter what I do, it doesn't want to add in a function node.
I don't see where you are attempting to add them. If you are trying to add the values from two separate messages then you have to first combine the two messages so that you get both values in one message. See this example in the cookbook https://cookbook.nodered.org/basic/join-streams

Thank you, I´ll try it if I get the other problem under controll 
Yes, I deleted the function where I tried to add 
What is coming out of the join node?
Hi @Becker you might be able to simplify things somewhat using node-red-contrib-buffer-parser.
Would you be willing to export your flows in a reply (select all the nodes to export, press CTRL+E) then...
```
paste flow between backticks like this
```

every second there are error:
The reason you cannot add the two values is because these values dont arrive in the + function node simultaneously and one or the other is undefined at that specific time.
As Colin suggested further up, you have to join again the values .. so the'll be in the same message and accessible for addition.
aah!
but there is a problem with the first join node, i changed to "10":
now all the values are in "T2"
The join node does its job .. waits for 10 messages from the 10 different topics, as defined in the preceding functions, and joins them. And its not in T2 .. its in msg.payload
now for the addition issue: add a join node between the two (2nd column) functions to join the messages.
you have to fully understand how this join node works .. i hope the video tutorial from the developers makes it more clear

I haven't studied the flow in detail, but why is it necessary to have the first Join node? Could that not just be a Switch node to send the data off to the displays?
Hi again, as mensioned earlier, this is how you can do it with buffer parser...
(obviously I dont have your invertor so all values are simulated - zero)
this is the flow i did...

These are how i decided to group the reads up into 4 parts & the offsets I used in the buffer parser...
NOTE: I couldnt find an exact manual but this one suggests values are S32 (Signed 32 bit integers)

it was important that every "join" has the right value:
at the beginning of this thread it was wrong (2), so every function node got all the values.
Its good that you have a solution - though i do suspect you will soon find an issue since your flow doesnt calculate int32 values (you only take the hi WORD in msg.payload[1]) where as the buffer parser takes care of number type conversion from a 2 WORDS to signed int 32 bit. As soon as any of your numbers go over 32767 will have incorrect values in your flow. 
The reason my flow didnt work for you is likely due to the byte swapping or me selecting the int32 (le) data types (you only needed to tweak them as I documented on the screen shot).
Hi Becker,
Steve is right. I searched also on the SMA website and it seems your devices use 32bit values and need to be parsed the correct way with Steve's solution.
I guess that explains why when we were trying to request for a value, in your other topic, with quantity 1 you were getting an error.
yes, but I works fine.
I don´t understand the grouped registers with the buffer parser, its too complicated for me. 
it works:
32bit:
=trash
Sorry I assumed signed values.
When any of the values go above 16bit max 65535, the values in your node-red flow will be incorrect as you are only using element 1. The buffer parser takes care to correctly convert the 2 values into 32bit numbers.
