New version 2025-11-24. Will take some hours to auto-update as usual.
Since the app limits the amount of characters, when using the Advanced input to target multiple devices using the also keyword, in practice you could not write multiple devices since device IDs are 36 chars long. The workaround was using the Rules API.
Now there’s another way which is writing only the first 8 characters of the ID, that is, the ones before the first hyphen. That should be random enough to identify a single device while keeping it short, but I guess it does not hurt to double check, in the AWA you can sort by device ID and quickly see if two devices start with the same prefix.
These two examples to target three devices (the one of the routine and two additional ones) are equivalent:

autoStep 10 also 3b916b24-0d21-4700-911a-d6650569931c,c0c8b96f-eb21-4bef-9b11-cbf51c44805b -
autoStep 10 also 3b916b24,c0c8b96f
You can choose to write all the devices in long form or in short form, but you can’t mix both for performance reasons.
As a reminder, to target multiple devices they have to be using the same driver. Popular use cases for the also include the auto stepping, setting the same random colour to multiple lights or in general trying to minimize the popcorn effect.
