If would need to be a condition based action, based on what fan speed is currently selected. In ESPhome you can do if/then/else statements, but I’m not sure if you can do if/elseif/elseif/else or not…
There is likely a way to do this with lambda’s but I’m not skilled in writing those.
ESPhome code: (not complete)
</s> <s>button:</s> <s> - platform: gpio</s> <s> name: Fan Button</s> <s> id: button</s> <s> on_press:</s> <s> then:</s> <s> - if:</s> <s> condition:</s> <s> - switch.is_on: switch_low</s> <s> then:</s> <s> - switch.turn_off: switch_low</s> <s> - switch.turn_on: switch_med</s> <s>Hopefully you get the idea, but I would imagine there is a more elegant way to do this with lambda’s.
EDIT: see solution from RoadlikkUK below.

Thanks for the quick reply. Unfortunately, I do not quite understand the solution. I have a button and would like to achieve a different state with each press on it. So the speed Slow Medium and Fast or Off. In C++ this would probably be a counter from 0 to 3 and the assignment via a switch-case statement. This should be possible with ESPHome! Only I do not know how…

Check this link, there is an Action for that.
Increments through speed levels of the fan with the given ID when executed. If the fan’s speed level is set to maximum when executed, turns fan off.
button:
- platform: template
name: Fan Button
id: fanbutton
on_press:
- fan.cycle_speed: fan_1

Wow! I had no idea that existed, thanks. I may as well delete my last nonsense post!

With the fan domain you can create components that appear as fans in the Home Assistant frontend. A fan can be switched on or off, optionally has a speed between 1 and the maximum supported speed of the fan, and can have an oscillation and direction output.
How is this supposed to help me with my automation in the device? I have read everything and think that this is mainly about the front end. If I’m wrong please show me a solution with the platform gpio so a physical button.

Try this instead then, it would seem that the last example was for a ‘virtual’ button, not physical.
binary_sensor:
- platform: gpio
pin:
number: GPIO01
mode: INPUT_PULLUP
inverted: True
name: "Fan Cycle"
filters:
- delayed_on: 10ms
on_press:
then:
- fan.cycle_speed: fan_1

No worries Dave, I used your example further up in this thread to change my fan from 3 buttons and 1 switch to the correct way with fan speeds. RF remote fan control

When I insert this example I get the following error message…
"Unable to find action with the name ‘fan.cycle_speed’.
Do I need to declare anything else?

OK, that’s true… I’ll look into that.
Alright, that’s weird because it’s fine now, in my fan config and compiling and uploading. I’m not sure what to say about that.
Is the fan.cycle_speed: pointing to your fan id:

The fan declaration does not exist for me because I did not know it yet. Honestly, I also do not know how to set this with me. I would like to switch only three solid state relays. Show you my code so far. The switches represent the relays. The push button is connected to D5.

Wow thanks for doing the work and rewriting the program. That’s how it works already. Thank you very much. One question for understanding…

The rewrite was a mash up of yours and @sparkydave ’s.
I’m not sure I understand your question, can I suggest you keep looking into ESPHome as that’s the only way you’ll understand it. Take this script/program/sketch for example and look into why it does what is does.

Yes that’s true I still have a lot to learn. Unfortunately, there are not so many examples of automation with esphome. If you have a source, please send it to me. I thank you again for your help.
Hello everyone, this is exactly what i was looking for. The proyect im starting to build.
I copied @RoadkillUK code, removed the I2C, temp sensor, and display becouse i wont be using it.
But im got some errors. I really didnt understand what i had to do. I changed some of the ID for the fan and finally started working.
this is how it ended up working for me:
fan:
- platform: speed
id: ceilingfan
output: custom_fan
name: "Ceiling Fan"
speed_count: 3
binary_sensor:
#Pulsador cambia velocidad en D0

on_press:
then:
- fan.cycle_speed: ceilingfan
output:
- platform: template
id: custom_fan
type: float
write_action:
- if:
condition:
lambda: return ((state == 0));
then:
# action for off
- switch.turn_off: low
- switch.turn_off: middle
- switch.turn_off: high
- if:
condition:
lambda: return ((state > 0) && (state < 0.4));
then:
# action for speed 1
- switch.turn_off: middle
- switch.turn_off: high
- switch.turn_on: low
- if:
condition:
lambda: return ((state > 0.4) && (state < 0.7));
then:
# action for speed 2
- switch.turn_off: low
- switch.turn_off: high
- switch.turn_on: middle
- if:
condition:
lambda: return ((state > 0.7));
then:
# action for speed 3
- switch.turn_off: low
- switch.turn_off: middle
- switch.turn_on: high
switch:
#Pin D1 Velocidad Baja
- platform: gpio
pin: 5
