Hello
if i have a function, can i write a for next or loop loop there, which reads a number of global data at each start, calculates it and then writes it with a new topic and payload?
E.g.
read all global values
go into the loop and edit the first value,
give the first value a new topic and the result into payload
send this to iobroker/influxdb
start the loop again with the second value
edit the second value with a new topic and the result intp payload
send this to iobroker/influxdb
..
..
..
24 times, then the process is finished for 24 hours.
Of course I can also write 24 functions which are triggered one after the other and read their values, edit them, create a topic and send it.
However, a single process would be simpler for extensions, adjustments and the overview.
However, as soon as I have written return once in my attempts, the function terminates, which was probably the intention of the inventor.
I have 48 variables which I load.
electricity meter yesterday 1-24 electricity meter today 1-24
,
calculate new electricity meter reading yesterday and write back
Now I want to send the new calculated meter reading today to iobroker/grafana
and continue with the next value.
it is all numbers and almost always the same, but
there are values where I have to divide the value by to 2 consumers
or subtract a value from a chain (total consumption heating, but there is the feed pump connected which I measure heating consumption is total consumption minus feed pump).
This is all no magic, I'm just trying to figure out if I can make a return msg.payload multiple times in a function
Thank you and I learned something new again.
I will try it out at the weekend.
there are soooo many great things in nodered.
So far all my ideas could be implemented, very impressive.
