How to change values of Zwave device?

Configuration Z-Wave
1

I have a neo coolcam Zwave power plug (a clone of Aeotec).

I need to read and then reset each day the value of energy consumption (to have a daily value).
Read is easy but resetting would mean send from HASS to the device a command, but how to do it, is it possible?

2

Here is the manual of the power plug

3

Research set_config_parameter.

4

But I don’t understand

action:
service: zwave.set_config_parameter
…??

5

can you give me an example?

I don’t know how to do this

“Lets the user set a config parameter to a node. NOTE: Use string for list values. For all others use integer.”

Or specifically:

  action:
    service: zwave.set_config_parameter
    data_template: {
      "node_id": 20,
      "parameter": 8,
      "value": 2
      }

Thanks, how would you store the value of energy of the previous day?

8

also which parameters … no parameter in this pdf says which is the energy reset …

Per the manual there is no command to reset the usage.
If you want a daily usage report, you’ll have to use a script and math it out.

A script would do?

Don’t know how to do it, can you give me an example?

Actually looks like you can do it via the history component:

Example:

sensor:
  - platform: history_stats
    name: Power Usage Today
    entity_id: zwave.your_device_name
    state: 'on'
    type: time
    end: '{{ now().replace(hour=0).replace(minute=0).replace(second=0) }}'
    duration:
      hours: 24

Replace the state with what ever state you’re tracking.

Hope this puts you in the right direction.

thanks trying now.

Like this shows the last 24 hours, like every minute is the last 24 hours correct?

I would rather have a value per day (from 00:00 to current time, and maybe retain the value of previous days)

13

What I posted would be the previous day’s worth of usage. So to do from 00:00 to ‘now’ it’d be like this:

sensor:
  - platform: history_stats
    name: Power Usage Today
    entity_id: zwave.your_device_name
    state: 'on'
    type: time
    start: '{{ now().replace(hour=0).replace(minute=0).replace(second=0) }}'
    end: '{{ now() }}'
14

Not sure I understand. Let’s make an example.

Today is 10:25 it shows from 00:00 to 10:25 or from 10:24 previous day to 10:25 today? (first is ok for me, second no)

15

My 2nd post would show you “from 00:00 to now” whatever your current time is :slight_smile:

16

Hi, I receive 0 all time …

Do you have the correct entity being monitored?

18

under sensor:

  - platform: history_stats
    name: Air Gilma Daily Energy last 24h
    entity_id: sensor.neo_coolcam_power_plug_12a_energy
    state: 'on'
    type: time
    end: '{{ now().replace(hour=0).replace(minute=0).replace(second=0) }}'
    duration:
      hours: 24
  - platform: history_stats
    name: Air Gilma Daily Energy from 00:00 to now
    entity_id: sensor.neo_coolcam_power_plug_12a_energy
    state: 'on'
    type: time
    start: '{{ now().replace(hour=0).replace(minute=0).replace(second=0) }}'
    end: '{{ now() }}

Perhaps @bokub may have some insight if this is possible with the component.

@anon35356645 this won’t work because the state that you want tracked is a numerical value, not ‘on’. I don’t think think component can track changing numerical values.
