YeeLight ceiling light cannot be detected in Homebridge after updating to firmware 1.5.9_0184


I have updated both the JiaoYue 650 and the ceiling light from firmware 1.5.5_0180 ti 1.5.9_0184 and now I cannot detect the light in Homebridge.
Is there any way to downgrade the firmware back to 1.5.5_0180?
Please help.
