Count air devices in space

I need help, I’m a bit stuck.
I’m trying to count all the different airdevices in a space, rename them, like TD1, TD2… Then i want to count how many I’v got of each in any given space.

my end gol is to writer to a parameters. But that is a later problem.

Thanks in advance!

Thats how I’ve got to the point to get a list of all air-devices in a list. within a list of all spaces. But its the summary that is the problem now. I need to get from the poit:

[0]MTN-400 + HMK-250/400
[1]MTN-400 + HMK-250/400
[2]MTN-400 + HMK-250/400
[3]MTN-400 + HMK-250/400
[4]MTN-400 + HMK-250/400
[5]MTN-400 + HMK-250/400
[6]RASTER GRL 595x595



The translation part I’ve managed, so now i have a list with


  1. List.GroupByKey with both inputs as your translated list.

  2. Count the groups.

  3. Join the count to the separator text and the Key from the group by key node.
