myStrom switch does not report current_power_w when it's zero

[messismore]

Home Assistant release with the issue:

94.4

Last working Home Assistant release (if known):

Operating environment (Hass.io/Docker/Windows/etc.):

Hass.io

Component/platform:

myStrom switch

Description of problem:

The switch's current_power_wattribute will not update when power consumption drops to zero but instead sticks to the last reported value. (It seems like Hass is no longer reporting it? When I query the state of the switch with the hass cli the attribute is no longer listed)

The component relies on https://github.com/fabaff/python-mystrom which correctly reports the switch's consumption.

Is this a problem with how Home Assistant deals with attributes? I noticed that when I change mystrom/switch.py to always return current_power_w = 0 the attribute does not show up in Home Assistant either…

Problem-relevant configuration.yaml entries and (fill out even if it seems unimportant): Switch

- platform: mystrom
  name: "mystrom_switch"
  host: 192.168.0.32

Sensor

- platform: template
  sensors:
    mystrom_switch_power:
      unit_of_measurement: "W"
      value_template: "{{ states.switch.mystrom_switch.attributes.current_power_w }}"

Traceback (if applicable):

Same here... My quick and dirty workaround was to always add 0.01 to the result returned by components/switch/mystrom.py, (current_power_w).

Depending on the version of home-assistant you're running, either edit components/switch/mystrom.py or components/mystrom/switch.py, look for def current_power_w(self):, change the return statement two lines below to return round(self.data['power'] + 0.01, 2) and finally restart home-assistant.

Hey thanks for getting back at me. I‘m running hass.io on a raspberry 4 and am using the standart integration (adding it to config.yaml). I ssh‘d as root but can’t find either of those folders, not even the components one.

@dezuber As far as I know, components in <config dir>/custom_components overwrite the built in ones, but I can't find it in the documentation right now.

You can get the original file here.

@messismore thanks for your reply. just created the folders \hassio\config\custom_components\mystrom and added the file you posted. doesn't seem to work...

[messismore]

@dezuber I just tried it and it seems to work. Did you make the change suggested by @matoxp?
