Legacy Electricity Meter API

Use meters module for new developments instead! The legacy electricity meter API only supports one electricity meter (the one configured as linked_meter_slot in meters_legacy_api/config) and can only report and process a subset of the supported electricity meter values. The legacy API is emulated by the meters_legacy_api module module.

meter/history

HTTP (curl)

A 48-hour history of charging power in watts. Missing values are indicated by null. The history is filled from back to front, so null values only occur consecutively at the beginning of the array if the ESP was restarted within the last 48 hours. Up to 720 values are output, which corresponds to one measurement value every 4 minutes. These measurement values are the respective average of these 4 minutes.

Example

last_reset int (s)	Unix timestamp of the time of the last meter reset.

meter/history

HTTP (curl)

A 48-hour history of charging power in watts. Missing values are indicated by null. The history is filled from back to front, so null values only occur consecutively at the beginning of the array if the ESP was restarted within the last 48 hours. Up to 720 values are output, which corresponds to one measurement value every 4 minutes. These measurement values are the respective average of these 4 minutes.

# $HOST e.g. warp3-AbCd

Write

curl http://$HOST/meter/reset -d 'null'

MQTT (mosquitto)

Name	Description
last_reset int (s)	Unix timestamp of the time of the last meter reset.

meter/history

HTTP (curl)

A 48-hour history of charging power in watts. Missing values are indicated by null. The history is filled from back to front, so null values only occur consecutively at the beginning of the array if the ESP was restarted within the last 48 hours. Up to 720 values are output, which corresponds to one measurement value every 4 minutes. These measurement values are the respective average of these 4 minutes.

# $HOST e.g. wem-AbCd

Write

curl http://$HOST/meter/reset -d 'null'

MQTT (mosquitto)

Name	Description
last_reset int (s)	Unix timestamp of the time of the last meter reset.

meter/history

HTTP (curl)

A 48-hour history of charging power in watts. Missing values are indicated by null. The history is filled from back to front, so null values only occur consecutively at the beginning of the array if the ESP was restarted within the last 48 hours. Up to 720 values are output, which corresponds to one measurement value every 4 minutes. These measurement values are the respective average of these 4 minutes.

http

mqtt

Triggers a one-time action. Messages retained via the broker are ignored.

Example

HTTP (curl)

# $HOST e.g. wem2-AbCd

Write

curl http://$HOST/meter/reset -d 'null'

MQTT (mosquitto)

Name	Description
last_reset int (s)	Unix timestamp of the time of the last meter reset.

meter/history

HTTP (curl)

A 48-hour history of charging power in watts. Missing values are indicated by null. The history is filled from back to front, so null values only occur consecutively at the beginning of the array if the ESP was restarted within the last 48 hours. Up to 720 values are output, which corresponds to one measurement value every 4 minutes. These measurement values are the respective average of these 4 minutes.

Example

meter/reset

Resets the energy meter. Empty payload. One of the following values must be passed: null, "", false, 0, [] or {}

http

mqtt

Triggers a one-time action. Messages retained via the broker are ignored.

Example

HTTP (curl)

# $HOST e.g. warp-AbCd

Write

curl http://$HOST/meter/reset -d 'null'

MQTT (mosquitto)

# $BROKER e.g. my_mosquitto.localdomain

Write

mosquitto_pub -h $BROKER -t $PREFIX/meter/reset -m 'null'

meter/last_reset

The time of the last meter reset (see meter/reset) as Unix timestamp. 0 if no reset was performed, or if no network time synchronization was available at the time of the reset.

Example

HTTP (curl)

# $HOST e.g. warp-AbCd

Read

curl http://$HOST/meter/last_reset

MQTT (mosquitto)

# $BROKER e.g. my_mosquitto.localdomain

Name	Description
last_reset int (s)	Unix timestamp of the time of the last meter reset.

meter/type_override

(Only WARP 1) Allows overriding the installed meter type if auto-detection does not work.

Example

HTTP (curl)

# $HOST e.g. warp-AbCd

Read

curl http://$HOST/meter/type_override

Write

curl http://$HOST/meter/type_override -d ''

or abbreviated:

curl http://$HOST/meter/type_override -d ''

MQTT (mosquitto)

# $BROKER e.g. my_mosquitto.localdomain
# $PREFIX e.g. warp/AbCd

Read

mosquitto_sub -v -C 1 -h $BROKER -t $PREFIX/meter/type_override

Write

With MQTT on $PREFIX/meter/type_override_update

mosquitto_pub -h $BROKER -t $PREFIX/meter/type_override_update -m ''

or abbreviated:

mosquitto_pub -h $BROKER -t $PREFIX/meter/type_override_update -m ''

Name	Description
type int	Electricity meter type to be used 0 - No electricity meter available 1 - Eastron SDM72 2 - Eastron SDM630 3 - Eastron SDM72V2 255 - Type override not active. Electricity meter type is automatically detected.

meter/history

HTTP (curl)

A 48-hour history of charging power in watts. Missing values are indicated by null. The history is filled from back to front, so null values only occur consecutively at the beginning of the array if the ESP was restarted within the last 48 hours. Up to 720 values are output, which corresponds to one measurement value every 4 minutes. These measurement values are the respective average of these 4 minutes.

Example

HTTP (curl)

# $HOST e.g. warp-AbCd

curl http://$HOST/meter/history
