Been searching around some, but haven’t really figured out how to write it…
I have two input_numbers and one input_boolean.
The first is input_number is “start hour” and the second is “stop hour”, and the input_boolean is just to activate or deactivate the “timer”.
How do I make that automation, so that it starts and stops at the chosen hours and when stopped, resets the input_boolean to inactive state.
I guess it’s fairly simple, but I cant wrap my head around it!
Thankful for any help 
I do it with two input_datetimes (not input_numbers) to control a binary sensor. The use of time only input_datetimes complicates things as they need today’s date added to be compared with now():
- platform: template
sensors:
lounge_ac_am_automation_time_active:
friendly_name: "Lounge AM Automation Time Active"
value_template: >-
{% set update = states('sensor.time') %}
{% set d = now().strftime("%Y-%m-%d ") %}
{% set t = now().timestamp() %}
{% set am_start = strptime(d + states('input_datetime.lounge_ac_am_on_time'), '%Y-%m-%d %H:%M:%S').timestamp() %}
{% set am_end = strptime(d + states('input_datetime.lounge_ac_am_off_time'), '%Y-%m-%d %H:%M:%S').timestamp() %}
{{ am_start <= t <= am_end }}
If you only want to match the hour with input_numbers it is a lot simpler:
binary sensor
- platform: template
sensors:
kind_of_timer:
friendly_name: "Kind of Timer"
value_template: >-
{% set update = states('sensor.time') %}
{% set t = now().hour %}
{% set start = states('input_number_start_hour')|int %}
{% set stop = states('input_number_stop_hour')|int %}
{{ start <= t <= stop }}
You can use the state of that binary sensor (trigger) in an automation to switch your input_boolean (action).
The template updates every minute curtsey of including {% set update = states('sensor.time') %}.
Hi again and thanks for trying to help me out!
I took your example and modified it a bit, really just replaced some names…
But the sensor never changed value from False to True, any ideas why?
I set the start time to 17 and end time to 18, and then waited until the clock showed 17, I was hoping the sensor would show “True” then, but it didn’t.
What am I missing here?
The sensor…
- platform: template
sensors:
varmeflakt_timer:
friendly_name: "Timer"
value_template: >-
{% set update = states('sensor.time') %}
{% set t = now().hour %}
{% set start = states('input_number_varmeflakt_start')|int %}
{% set stop = states('input_number_varmeflakt_stopp')|int %}
{{ start <= t <= stop }}
The inputs…
varmeflakt_start:
name: Starttid
icon: mdi:clock-time-two-outline
initial: 0
min: 0
max: 23
step: 1
varmeflakt_stopp:
name: Sluttid
icon: mdi:clock-time-five-outline
initial: 0
min: 0
max: 23
step: 1
…and last but not least, the automations for turning it on and off.
- alias: Starta värmefläkt
trigger:
- platform: state
entity_id: sensor.varmeflakt_timer
from: 'False'
to: 'True'
action:
- service: switch.turn_on
entity_id: switch.shelly_varmeflakt
- alias: Stäng av värmefläkt
trigger:
- platform: state
entity_id: sensor.varmeflakt_timer
from: 'True'
to: 'False'
action:
- service: switch.turn_off
entity_id: switch.shelly_varmeflakt
What version of home assistant are you on?
Latest, 0.115.2
Do you have a sensor.time?
Also that was meant to be a binary_sensor, not a sensor.
If you do change it use states 'on' and 'off', not True and False in your automation.
Ahh, okay, I’ve changed the sensor to a binary and changed the automations aswell!
I do have a sensor.time!
This trigger will be binary_sensor.varm... now.
- alias: Starta värmefläkt
trigger:
- platform: state
entity_id: sensor.varmeflakt_timer
That’s weird…that didn’t work 
The binary sensor didn’t change from off to on based on the values from the input_numbers.
What does this give you in the developer tools / template editor:
start: {{ states('input_number_varmeflakt_start') }}
stop: {{ states('input_number_varmeflakt_stopp') }}
now hour: {{ now().hour }}
time: {{ states('sensor.time') }}
It gives:
start: unknown
stop: unknown
now hour: 19
time: 19:10
But if I change from:
start: {{ states('input_number_varmeflakt_start') }}
stop: {{ states('input_number_varmeflakt_stopp') }}
now hour: {{ now().hour }}
time: {{ states('sensor.time') }}
to:
start: {{ states('input_number.varmeflakt_start') }}
stop: {{ states('input_number.varmeflakt_stopp') }}
now hour: {{ now().hour }}
time: {{ states('sensor.time') }}
I get the following:
start: 0.0
stop: 0.0
now hour: 19
time: 19:10
Which seems more accurate!
But I don’t know if the decimals will mess things up?
Doh. Yeah those should definitely be periods not underscores. Well done.
No the decimal points wont matter for less than / greater than comparisons. They just have to be numbers.
Why are your input numbers both zero though?
Both my sliders where at zero when testing, now, when set, they show up correct numbers!
start: 20.0
stop: 21.0
now hour: 19
time: 19:19
So now I’ll just have to wait and see how it plays out 
Okay, so it kinda works, the sensor gets set to “on” at specified hour, but for some reason it doesn’t get set to “off” at the next specified hour…any ideas why?
Can you post the sensor config and automation(s) involved?
See below!
- platform: template
sensors:
varmeflakt_timer:
friendly_name: "Timer"
value_template: >-
{% set update = states('sensor.time') %}
{% set t = now().hour %}
{% set start = states('input_number.varmeflakt_start')|int %}
{% set stop = states('input_number.varmeflakt_stopp')|int %}
{{ start <= t <= stop }}
- alias: Starta värmefläkt
trigger:
- platform: state
entity_id: binary_sensor.varmeflakt_timer
from: 'off'
to: 'on'
action:
- service: switch.turn_on
entity_id: switch.shelly_varmeflakt
- alias: Stäng av värmefläkt
trigger:
- platform: state
entity_id: binary_sensor.varmeflakt_timer
from: 'on'
to: 'off'
action:
- service: switch.turn_off
entity_id: switch.shelly_varmeflakt
Might it be something with this line?
{{ start <= t <= stop }}
Automations work, I’ve tried them both setting the state manually!
No, that looks valid.
Try:
{% set t = now().hour|int %}
Unfortunantly that didn’t help
I know what it is. Try this:
{{ start <= t < stop }}
t equal to your stop hour was keeping the sensor on.
