Learn tags

Every tag has a fixed number, the tag ID, e.g. 2041736115. So that you don’t have to work with numbers in routines and in the CMS, you learn tags once and give them a name – such as “Sanddorn-Massageöl” or “Card station 3”.

Learned tags belong to your account, not to a particular hub. A tag you have learned once is recognised by every one of your hubs.

The tag list

On the IoT devices › RFID hubs page, click Tags at the top right. The number in brackets shows how many tags your account knows.

The list shows Name, Tag ID and Learned on. Use the search field to find tags by name or number.

Learn tags

Learning only works with a connected hub – the hub must be able to report which tag is placed.

1. Open Learn tags – in the tag list, in the detail panel of a hub or by right-clicking a hub.
2. Choose the Hub on whose readers you place the tags.
3. Place the tags on the readers one after the other. Every unknown tag appears as a separate row, with the reader it was placed on. Tags that are already known are hidden.
4. Give each tag a Name. If you leave the field empty, the tag ID is used as the name.
5. Click Add tags.

Tip

• A row stays even if you remove the tag again. This way you can learn many tags on a single reader: place, remove, place the next one.
• If an unknown tag is placed on a reader, you also see it in the readers column as … · unknown. Clicking it opens learning directly.

Rename or delete a tag

In the tag list, you rename a tag with the pencil or delete it with the trash can.

Routines that use the name

A routine can recognise a tag by name or by tag ID (see RFID in routines).

• Rename: Routines that filter by name only recognise the tag afterwards if the new name matches the filter.
• Delete: Routines that use the name no longer fire for this tag – a deleted tag no longer has a name. Routines using the tag ID keep firing. The delete dialog names the affected routines.

A deleted tag is not lost: if you place it again, it appears as unknown and can be learned again.

Name or tag ID – which is better?

	By name	By tag ID
Readability	Routines are understandable at a glance.	Routines show the numbers together with the name.
Groups	With Contains, one filter covers many tags at once, e.g. all whose name contains “Wine”.	Each tag is selected individually.
Replacing a tag	A replacement tag with the same name works immediately.	The routine has to be switched to the new number.
Renaming	Can affect the routine (see above).	No effect.

For most uses, by name is the better choice – especially if you name tags systematically (“Wine Red …”, “Wine White …”).
