How to change values of Zwave device?

Configuration Z-Wave

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.

10

A script would do?

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

11

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.

20

@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.

21

You’re right @Maaniac , the history_stats component can only track how long a component were in a specific state. It’s not designed to read and save values.

22

How hard would it be to modify for such a task, assuming time was the only type a numeric state would be valid with?

23

Is there a way to read the config state as a sensor? To template the output of print_config_parameter?

I haven’t tried. print_config_parameter is a service, right? I guess you could read it via the API with a RESTful sensor and parse its output.
