The additions for three-phase measurements would produce a very long table due to all the combinations that are possible, so these additions are broken down to their base components.
input.phases (3 for three-phase, absent or 1 for 1phase)
output.phases (as for input.phases)
Any input or output is considered a valid DOMAIN.
input (should really be called input.mains, but keep this for compat)
output (should really be called output.load, but keep this for compat)
Voltage, current, frequency, etc are considered to be a specification of the measurement.
With this notation, the old 1phase naming scheme becomes DOMAIN.SPEC
Example: input.current
When in three-phase mode, we need some way to specify the target for most measurements in more detail. We call this the CONTEXT.
With this notation, the naming scheme becomes DOMAIN.CONTEXT.SPEC when in three-phase mode.
Example: input.L1.current
L1-L2 \ L2-L3 \ L3-L1 for voltage measurements L1-N / L2-N / L3-N /
L1 \ L2 for current and power measurements L3 / N - for current measurement
For cursory readers — the following couple of tables lists just the
short SPEC component of the larger DOMAIN.CONTEXT.SPEC naming scheme
for phase-aware values, as discussed in other sections of this chapter.

that were exposed through ups.status.
The battery.charger.status can have one of the following values:
charging: battery is charging,
discharging: battery is discharging,
floating: battery has completed its charge cycle,
and waiting to go to resting mode,
resting: the battery is fully charged, and not charging nor discharging.

multiple sensors can be exposed using the indexed notation. ambient.*, without index or using 0, relates to the embedded sensor. For example: ambient.temperature represent the embedded sensor temperature. Other sensors (external, communication card, …) can use indexes from 1 to n.

This is a refinement of the outlet collection, providing grouped management for a set of outlets. The same principles and data than the outlet collection apply to outlet.group, especially for the indexing n and "outlet.group.count".
Most of the data published for outlets also apply to outlet.group, including: id, name (similar as outlet "desc"), status, current and voltage (including status, alarm and thresholds).
Some specific data to outlet groups exists:
| Name | Description | Example value |
|---|---|---|
outlet.group.n.type | Type of outlet group (OPAQUE) | outlet-section |
outlet.group.n.color | Color-coding of the outlets in this group (OPAQUE) | yellow |
