 Notes
Works with 2.4GHz Wi-Fi only (no 5GHz support)
To reset to factory mode: power cycle 7 times quickly
 
The first rule of upgrading: If it ain't broke, don't fix it!
In other words, ensure that there is a good reason to mess with a working installation (e.g., a need to use a new feature or address a found problem fixed in the current version).
 
Danger:
 If you maximum all channel at the same time, it will highly possible damage the bulb and we will not provide warranty in such case.
