couldn't find an alternative way to contact you.

Love all your examples. I was wondering if there was a way to add more LEDs to the same file? I have tried altering your files but to no avail

any help you can give would be appreciated thanks Sam

Hi Sam, It's possible! In this sketch, two white LEDs are controlled; in this one, two RGB LEDs are controlled.

If you need more LEDs, just apply the same logic (2 MQTT topics: state/command, a function to set the new state, a function to publish the new state and handle the command topic in the MQTT callback function).

Good job! In your sketch, you can use D1 instead of 5. You also forget to update the header introduction.
