As @bertreb stated milight-reloaded is the starting point as the product description of the Miboxer WL5 claims the product to be compatible with FUT089, FUT088, FUT096, FUT092, FUT007, FUT091, T1, T2, T3, T4, B8, B1-B4 remotes. This way, the WL5 should work with MilightFullColorZone which maps to the command set of the FUT092 remote. It is important however, to pair the WL5 with the correct remote model.
Well, that’s the theory given that the product works as advertised. On the base library node-milight-promise I have written for the plugin a user raised an issue regarding the YL5 device which appears to be very similar to the MiBoxer. He said it did not work with the existing code and reverse engineer a different command set he promised to release soon. However, I am not yet sure whether or not he paired the device as advised.
