For the past couple of years this is briefly discussed in forums. However no solution has been found.
Is it possible to deactivate bluetooth of the hue bulbs?
Interference is a major problem. In a distant room that i get borderline adequate wifi 2.4ghz signal, it disconnects when the bulb is turned on… Not really solid proof but ~8bulbs for a small size apartment with additional interference from neighboring routers - go figure out the extent of interference! I am annoyed that there is no option officially provided.
