Sorry your grouping function is not behaving - please check out the troubleshooting below. If the tips don't help, please email us at support@flowtoys.com and we'll take care of you.


If you're experiencing radio issues, it could be due to these potential issues:

  • lights have different versions of firmware
  • lights are not grouped correctly
  • radio crashed
  • faulty radio
  • radio broke off the circuit board


1. Ensure all your lights have the same firmware


2. Ensure lights are grouped correctly

  • Click here for grouping instructions
  • Confirm they are NOT in a temp./open group -> go to P5M1. In current firmware, it should be white.


3. Radio might have crashed

  1. Try a soft reset - this often fixes it. Not typical but you may need to reset it a few times, then group again.
  2. If a soft reset doesn't work, try a power-cycle

4. Faulty radio

  • It’s possible for a radio to be partially defective/work intermittently. Usually a bad radio can receive well, but not transmit well. You may notice a delay in other lights responding to it. Mark the suspected light - if you can confirm it is the faulty one, we’ll replace it.


5. Radio broke off the board

  • Open the capsule shell (see soft reset/power cycle video below) 

  • Check if the radio is breaking off the board or missing

    • If radio is breaking off the board or missing, please email us at support@flowtoys.com for replacement instructions.
