My first zigbee device was Sylvania (73685) rgbw led strip. On it's own it worked fine but once I started trying to add sengled zigbee bulbs I kept having problems with pairing the bulbs or keeping them connected. Zigbee uses 2.4ghz so I thought maybe interference so lowered power output on wifi AP 2.4ghz band & even turned it off for testing but didn't help. I think I read somewhere that sylvanias caused that problem. I unplugged sylvania led strip, reset & rejoined everything else and had zero problems. Tried to add the sylvania back in and disconnect problems came back after awhile. It was past the return period so now I keep it unjoined and plugged into a zigbee smart outlet. I sometimes have to remove power from it to join new devices or when I restart zigbee controller. Currently have mix of sengled bulbs, thirdreality plugs, sonoff plugs & sensors, and single aqara tvoc all working together fairly reliably.
