Change an entity attribute without a service call

Hey there,

I am a HA beginner, so I am sorry if this is a stupid question!

But is there a way to change the value of a specific attribute of an entity without a service call?

I am in the process of implementing my Xiaomi Standing Fan 2 (dmaker.fan.p18) in to my Homeassistant Dashboard. Therefore I am using the integration of Xiaomi Mi Smart Pedestal Fan by syssi . I managed to implement almost all features. At the moment the mentioned integration just supports a service call to adjust the brightness of the led which are built into the fan. However, my fan does not support these features. The Standing Fan 2 has no dimmable led, they can either be on or off (led: true/ false).

Now since there is no service call in the integration is there a way to set the value with an automation/ switch or script?

thanks very much!

No.
