Sounds like you’re looking for something along the lines of this.
I have one that would occasionally have the disconnect issue. I also wanted to add tunable white bulbs for circadian lighting. This is the solution I used and it works great. I ultimately had to ditch the cheap Costco bulbs because they would frequently disconnect from WiFi and went with some Ikea zigbee bulbs in their place.
If you need more details on how to do it, just let me know and I’ll try to walk you through it. I use HA but it should be easily accomplished on HE as well.
