MQTT Update Period

Hi!

I am running my Shelly 3EM as an MQTT-sensor in Home Assistant. However - the Shelly sends about 20 updates per minute and "value" (e.g power, voltage etc) which means that only one sensor, say L1 Power, results in 29 000 datapoints per hour.

I have tried setting mqtt_update_period and update_period to different values, but it does not affect the above.

Is there any way to change the update frequency sent from the Shelly?

Hi!

I found a solution in Home Assistant after all. The filter module makes sure that we only record 1 value per minute to history, but as a new sensor called "Voltage - L1 Filtrerad".

The "Recorder" module makes sure that we don't record any data at all to history for the original sensor.

Sorry but the indentation went wacko when pasting.

- platform: filter
    name: 'Voltage - L1 Filtrerad'
    entity_id: sensor.voltage_L1
    filters:
- filter: time_throttle
        window_size: 00:01

recorder:
  exclude:
    entities:
- sensor.Voltage_L1
