I would like to use the bulb template for my dimmer modules which are controlled by @cobra OneToMany app.

Question is: are the functionally the same but with different icons? Or is the some basic difference?

Thanks

Functionally the same. Both send on/off and level.

Are there any differences between the Dimmer and Bulb template, other than the default icon? If there is no difference, why are there two separate templates?
