EDIT:
I created a much smoother and better solution for this problem. Check the following post to now more about it.
Hi @bartplessers,
I have been working on these recently. I have the same Ikea controller and I wanted a smooth solution for this. I found this post where the same is done but with a Xiomi controller: Finally - a cheap WIRELESS switch that dims! Xiaomi Switch Gen1. I started adapting it from the solution found on this post, but I have changed some things. The main thing I changed was to create a python script to dim up/down smoothly.
I created a package for it:
automation:
###################

You will need to change:
- YOURLIGHT: Your light entity
- YOURCONTROLLER: Your controller
You can add this file on packages folder and on the configuration.yaml:
homeassistant:
packages: !include_dir_named packages
python_script:
Then, you will need to add the following script (change_attribute_light_smoothly.py) inside /config/python_scripts:
input_boolean = data.get("input_boolean")
light_id = data.get("light_id")
delta = data.get("delta")
attribute_id = data.get("light_attribute", "brightness")
delay = data.get("delay", 350)
attribute_mapping = {
"brightness": {"min": 1, "max": 255},
"color_temp": {"min": 153, "max": 500},
}
exit_service = False
while True:
switch_input = hass.states.get(input_boolean).state
if switch_input == "off":
break
light = hass.states.get(light_id)
attr_value = light.attributes[attribute_id]
attr_value = attr_value + delta
if attr_value < attribute_mapping[attribute_id]["min"]:
attr_value = attribute_mapping[attribute_id]["min"]
exit_service = True
elif attr_value > attribute_mapping[attribute_id]["max"]:
attr_value = attribute_mapping[attribute_id]["max"]
exit_service = True
service_data = {"entity_id": light_id, attribute_id: attr_value}
logger.warning(f"Service data: {service_data}")
hass.services.call("light", "turn_on", service_data)
if exit_service:
break
time.sleep(delay / 1000)
I hope this helps you with your needs.
