The main issue affecting Radion G5s, connectivity with the Mobius app, have been resolved with the latest firmware update. Moreover, several improvements and defect fixes were made to improve overall product reliability. One defect that was found was regarding properly saving settings such as Lunar Phases, Acclimation, and Fan Shutdown. If these settings appear to be out of sync, please toggle the setting to the desired value. As a last resort, the light can be factory reset and added back into the Mobius app.
In the case of the fans there are two options:
1) Max Fan Speed
2) Fan Shutdown Enabled
You'll likely want to enable 2) Fan Shutdown Enabled.
The side effect of some of your settings having reverted is just the nature of the beast when it comes to fixing some aspects of the program, but I am very sorry for any frustrations that it may have caused. You can be very relieved that this was a major fix for the main issue many of us have experienced: connectivity issues.
