Input

The devices, tags, or tag combinations whose data samples trigger a rule.

The input of a rule defines which devices trigger its logic. Each time an input device sends a data sample to akenza, the linked logic block is evaluated with that sample.

Selecting the input type

A rule can have one or more inputs of three kinds:

Input	Triggers the rule for
Device	One device. Any device can be selected, regardless of its connectivity.
Tag	Every device that has the tag assigned.
Tag combination	Every device that matches a logic expression of several tags.

Selecting the input devices of a rule

Use the search field to find devices by name. A device can only be added once per rule, so devices that are already added cannot be selected again.

All devices selected by a tag or tag combination should send data with the same schema. The logic block reads the same topic and data key from every device, so a device with a different schema cannot be evaluated.

Timed rules only support devices as input. A rule with a tag or tag combination input is aborted when its timer triggers it.
