My goal is to have an option to continue running a fan for 3 different durations. To easily select the times I’d like to display the choices as buttons. These should be like an input_select in that it makes sense to only have 1 option (or none) selected at a time. I believe I’ve got the UI somewhat how I want it using this for the card:
I’m still in the testing phase as well as trying to determine if I’m even going about this the best way seems it seems rather convoluted to me. I do get this error thrown when I try the “30 minute timer” so with this code it’s not working properly yet.

I initially tried using a timer and passing the duration based on which button was pressed but I couldn’t get that to work but I’m a little stuck on how to clean up this mess and get it to work.
Continue running a fan…as in “when you click it, it will just off after X minutes”? Or “Adds X minutes to the current fan timer?” Or maybe this will turn on a fan for X minutes.
I think I would still create an input_select. Then, I would have the state change of that do other things.
# In configuration.yaml
input_select:
fan_time_select:
name: Garage Fan On Time Minutes
options:
- "OFF"
- "30"
- "60"
- "90"
icon: mdi:timer
I would also create a timer.
fan_timer:
laundry:
duration: '00:30:00'
The reason I would use a timer is because calling an automation that is currently waiting in a delay state will cause the automation to finish. It will skip the current and all future delays and execute everything in order, then trigger again and start over. So if you were to press the button again, it would finish, turn off the fan, then turn it right back on. The timer solution is better and gives you the ability to see a countdown timer for free!
Now you want to tie the main functionality to this input_select.
automation:
- alias: Update Fan Timer
trigger:
# Trigger whenever the input_select state changes.
platform: state
entity_id: input_select.fan_time_select
condition:
platform: template
entity_id: input_select.fan_time_select
# Ignore state changes to '0', or 'OFF', or whatever we want to set the off state.
value_template: "{{ not is_state('input_select.fan_time_select', 'OFF') }}"
action:
# In all cases, the fan needs to turn on. If it's already on....this wont affect anything.
- service: switch.turn_on
entity_id: switch.fan_entity_id
# The fan will turn itself off when the timer reaches 0. So all we have to do
# is start (or restart) the timer with the new duration.
- service: timer.start
entity_id: timer.fan_timer
# Sets the duration to the time select. This must be in '00:00:00' format.
duration: "00:{{ states('input_select.fan_time_select') }}:00"
- alias: Fan Timer Expired
trigger:
# Turns off the fan only when timer expires normally.
- platform: event
event_type: timer.finished
event_data:
entity_id: timer.fan_timer
action:
- service: switch.turn_off
entity_id: switch.fan_entity_id
# Now that fan is off, reset the select to 'off' position.
- service: input_select.select_option
data:
entity_id: input_select.fan_time_select
option: "OFF"
Now if you want to keep your crazy button setup, just have them call input_select.select_option as the service. This will now only set the input_select state which will fire the automation. We don’t have all of these corner cases to handle who or what started the fan. If you start it with the input select, it will turn off after X minutes.
Hi and thanks for responding. I just wanted to clarify what I have and what I’m trying to do. I have an air filtration system in the garage for woodworking. It is a 3 speed fan that I’ve replaced the controller with a Sonoff 4Ch Pro running Tasmota firmware. On the 4th channel I have a separate regular fan which is the 1st element in this card:
So I want to be able to select a speed and run the fan when I’m in the garage. When I’m done I want to set a timer that will turn off the fan after the selected amount of time. I’ve got a small 7" touch screen in the garage so I wanted to make the interface as slim and easy to use as possible which is why I wanted just buttons instead of drop down menus like input_select does.
I’ll have to re-read your solution to see if I understand what you’re suggesting. I definitely think the timer is a better solution but I’ve been struggling a bit just to get the card to look close to how I wanted and that limited what solutions I could use to pass information to scripts, automations, timers.
@GeorgeIoak - Did you finally get that right? I’m trying to do a similar (but simpler) thing. I just want to run a timer by choosing from three different durations with a button for each.
I did but my method broke many versions ago and I’ve been staring at this on my home page ever since because I haven’t gotten around to figuring out how to make it work again!
