Have been struggling with this problem for days and no matter what I try I am unable to get there. I have a home assistant input number that I’d like to use in delay functions. But it requires a either a float or a string where I’d like to use an integer.
I want to use it to set the delay time in minutes.
I obtain the value from home assistant as follows:
sensor:
- platform: homeassistant
id: max_run_time_minutes
name: "Max Run Time - All Zones"
entity_id: input_number.irrigation_max_duration
I want to use it with the delay function of this block:
switch:
- platform: template
name: $friendly_name $zone_4
icon: $sprinkler_icon
id: zone_4
lambda: return id(relay_4).state;
optimistic: true
turn_on_action:
- switch.turn_on: relay_4
- delay:
minutes: max_run_time_minutes
# - delay:
# minutes: float_max_run_time_minutes
# - delay: $max_run_time
# - delay: !lambda "return id(max_run_time_minutes) & 'min';"
- switch.turn_off: relay_4
turn_off_action:
- switch.turn_off: relay_4
ESP Home complains that minutes expects a float. I tried to set up a global float but that doesn’t work either.
I have managed to use a substitution to set the delay time:
substitutions:
# Set Max Run Time Here: =============================#
max_run_time: "10min"
# Sets delay between switch turn on and switch turn off
#======================================================#
But I can’t figure out how to get that back to home assistant.
Tried this without success:
text_sensor:
- platform: template
name: "Irrigation Max Run"
id: str_delay_setting
lambda: |-
return $max_run_time
I would like to set an initial value within ESPHome and update it with a home assistant value, or at least return that setting to home assistant.
Can anyone point me in the right direction. Just can’t seem to figure it out. Any help would be appreciated. Thanks for reading.

Don’t you want minutes: id(max_run_time_minutes).state ?

Edit: What Nick said may be your problem - I missed that…
Try converting to float in lambda. All platform: homeassistant sensors are strings.
turn_on_action:
- switch.turn_on: relay_4
- delay: !lambda "return atof(id(max_run_time_minutes).state.c_str()) & 'min';"
Or something like that
Although you may be better off converting into a variable, I can’t tell if the above format will work. I had to do a lot of this for the display component.
Thanks… I tried:
switch:
- platform: template
name: $friendly_name $zone_4
icon: $sprinkler_icon
id: zone_4
lambda: return id(relay_4).state;
optimistic: true
turn_on_action:
- switch.turn_on: relay_4
- delay:
minutes: id(float_max_run_time_minutes).state
# - delay:
# minutes: float_max_run_time_minutes
# - delay: $max_run_time
# - delay: !lambda "return id(max_run_time_minutes) & 'min';"
- switch.turn_off: relay_4
turn_off_action:
- switch.turn_off: relay_4
Still says it wants a float, but it is a float:
globals:
- id: float_max_run_time_minutes
type: float
initial_value: '10'

'10' is not a float, it is a string.
Thanks, I sure would like to assign it to a variable if I can figure out how. My understanding is that delay requires a string. I have used a substitution to set the delay…
substitutions:
max_run_time: 10min
switch:
- platform: template
name: $friendly_name $zone_4
icon: $sprinkler_icon
id: zone_4
lambda: return id(relay_4).state;
optimistic: true
turn_on_action:
- switch.turn_on: relay_4
- delay: $max_run_time
- switch.turn_off: relay_4
turn_off_action:
- switch.turn_off: relay_4
Now that I know that all home assistant values are strings, perhaps a lambda function to append “min” to the value would work.
Thought this would work:
- switch.turn_on: relay_4
- delay: !lambda "return id(max_run_time_minutes).state & 'min';"
Alas…

Not sure why it thinks it’s a float (or an int) if “All platform: homeassistant sensors are strings.”
OK, so it is not possible to define an initial value as a number only as a string? Even though, as per the example on the ESP Home site , it has been defined as an integer.
# Example configuration entry
globals:
- id: my_global_int
type: int
restore_value: no
initial_value: '0'

I convert delays to milliseconds, input number is used as min in the frontend
## time pump is on
- platform: homeassistant
id: pump_start
internal: true
accuracy_decimals: 2
entity_id: input_number.pump_start
on_value:
- globals.set:
id: start
value: !lambda 'return id(pump_start).state * 1000;'
Then save it in a global, you can set a default here
## time pump is on start
- id: start
type: int
restore_value: no
initial_value: '1200'
Drop state to use global in lambda
!lambda 'return id(start);'

This looks promising. Thanks a lot.

Just use delay and not the extended config
- delay: !lambda 'return id(start);'

You said earlier that the system seemed to want a float?

I thought the quotes '' made it a string. But hey, I was wrong once before

Yeah, I was trying two different methods…
- delay: $max_run_time # expects a string .. like "10min"
…and…
- delay:
minutes: float_max_run_time_minutes #expects a float
No worries, thanks for your help.
Thanks, this works very well.

You need to include state.
!lambda 'return id(ontime).state';
