Python sensor creation oddities

Mariusthvdb · March 14, 2018, 9:09am

HI,

i have this little python code section the sets the feedback i get for my alarmclock in 2 ways: a text bit, and a sensor with a badge:

All seems fine, until I check the state.state of the sensor, and its showing On Off, in its variations. Apparently it shows both the weekdays and weekends on/off setting. How could I correct this in the python (see below) so that it shows only 1 state…

relevant creation line is

hass.states.set('sensor.alarms_badge','', {

where ive taken out the state.state now with this effect:

(only weekdays showing)

using:

hass.states.set(‘sensor.alarms_badge’,state.state, {

shows on Off:

WE off Wd Off

also, why the wD state is shown with a capital O and the wE state without is unclear to me, since i don’t set it manually. Or would that be because it currently is a weekday?

refactored it a bit, same logic, easier to follow:

##########################################################################################

##########################################################################################

from datetime import datetime

alarms_prefix = ['alarmclock_wd', 'alarmclock_we']
alarms_wfilter = [range(1,6), range(6,8)]
alarms_desc = ''
mydict = {'hidden':hidden, 'order':order}

for entity_id, filter in zip(alarms_prefix, alarms_wfilter):
    state = hass.states.get('input_boolean.{}_enabled'.format(entity_id))
    if state:
        if state.state is 'on' and datetime.now().isoweekday() in filter:
            state = hass.states.get('sensor.{}_time_template'.format(entity_id))
            alarms_desc = '{}{}, '.format(alarms_desc, state.state)

if (alarms_desc == ''):
    mydict['entity_picture'] = '/local/badges/alarm_off.png'
    mydict['friendly_name'] =  'Relax'
    mydict['unit_of_measurement'] = 'Off'
    alarms_desc = '%- Alarm clock is not set, relax'
else:
    mydict['entity_picture'] = '/local/badges/alarm.png'
    mydict['friendly_name'] = alarms_desc[:-2]
    mydict['unit_of_measurement'] = 'On'
    alarms_desc = '/- Alarm clock set at ' + alarms_desc[:-2]

hass.states.set('sensor.alarms_badge', '', my_dict)

It’s not showing both values. This is because you are setting the unit of measure to on. Normally, the sensor object would have a number in the circle instead of an image. Then the units are displayed in that nice little box at the bottom of the round sensor object. If you remove mydict[‘unit_of_measurement’], you will not have the on On, off Off. Normal sensors would be a temperature sensor. If the temp was 25, and the unit_of_measurement was ºF, then the state would be 25 ºF. Your state is on, and your unit_of_measurement is On, so your state is on On.

wow, thanks!

trying to understand all of this, and hope to translate that to my bigger script… might need your help again soon magic how you do this, im trying to learn here, but this is kind of on the horizon of my imagination…

i do get this import not found error though, so no fun yet:

btw, noticed today, and check the top image that the alarm is off, and the time-wd icon still showing the clock wile it should have have shown mdi:close-circle…

see:

sensor:
  - platform: template
    sensors:
      alarmclock_wd_time_template:
        friendly_name: 'Time wd'
        icon_template: "{{ 'mdi:alarm' if is_state('input_boolean.alarmclock_wd_enabled', 'on') else 'mdi:close-circle' }}"
        value_template: '{{ "%0.02d:%0.02d" | format(states("input_number.alarmclock_wd_hour") | int, states("input_number.alarmclock_wd_minute") | int) }}'

I’ve checked the state in the dev tools, and that is correct showing the icon name:

what could be up?

you may not be able to from datetime import datetime in the spot I put it.

Might need to do this:

##########################################################################################
## Alarm clock
## https://github.com/maattdiy/home-assistant-config/blob/master/config/packages/alarmclock.yaml
##########################################################################################

alarms_prefix = ['alarmclock_wd', 'alarmclock_we']
alarms_wfilter = [range(1,6), range(6,8)]
alarms_desc = ''
mydict = {'hidden':hidden, 'order':order}

for entity_id, filter in zip(alarms_prefix, alarms_wfilter):
    state = hass.states.get('input_boolean.{}_enabled'.format(entity_id))
    if state:
        if state.state is 'on' and datetime.datetime.now().isoweekday() in filter:
            state = hass.states.get('sensor.{}_time_template'.format(entity_id))
            alarms_desc = '{}{}, '.format(alarms_desc, state.state)

if (alarms_desc == ''):
    mydict['entity_picture'] = '/local/badges/alarm_off.png'
    mydict['friendly_name'] =  'Relax'
    mydict['unit_of_measurement'] = 'Off'
    alarms_desc = '%- Alarm clock is not set, relax'
else:
    mydict['entity_picture'] = '/local/badges/alarm.png'
    mydict['friendly_name'] = alarms_desc[:-2]
    mydict['unit_of_measurement'] = 'On'
    alarms_desc = '/- Alarm clock set at ' + alarms_desc[:-2]

hass.states.set('sensor.alarms_badge', '', my_dict)

Not sure, that’s something that I would need to debug into personally.

Mariusthvdb · March 15, 2018, 7:51pm

will do, report back.

btw, what does the alarms_desc[:-2] do with the alarms_desc. never found the docs to learn what it means? if you have a pointer to that id appreciate

if you have a string or list, it allows you to grab portions of it.

Example:

mystring =‘123456789’
foo = mystring[:-2] would return everything before the second to last digit (i == -2, where last item in collection is -1)
foo = mystring[2:] would return everything after the 3rd index (i==2, where i starts at 0)
foo = mystring[2] would return the 3rd index (i==2, where i starts at 0)

This is all standard list/string manipulation. Just about every software language uses something like this.

bingo!
had to change this too (found it after checking ten times…)
hass.states.set('sensor.alarms_badge', '', mydict)

thanks! bit puzzled by the range setting though, seems they overlap now (6)?

petro · March 16, 2018, 12:52am

index’s in lists are off by 1

So a range of 6, range(6) returns [ 0,1,2,3,4,5 ]. You only want days 1-5, hence Range(1,6) which returns [ 1,2,3,4,5]
