The other alternative if for some reason you really want smart bulbs, is to use a smart switch which will not cut power to the smart bulbs.
There are three different kinds of these.
-
put a child lock on the existing switch and then add a battery operated smart switch on the wall next to it to operate the lights. There are many different options for these devices.
-
replace the dumb switch with a smart switch which is specifically designed to leave current to the bulbs at all times and control them by sending a message to the hub which then send a message to the bulbs
-
get a smart switch cover which fits over the top of the existing dumb switch. This device will let you operate the bulbs but prevents power being cut off to them.
You can read more about these choices in the following community FAQ
Any of these can be a good choice, it just depends on the details of what you want to do.
People often want to keep smart bulbs for one of two reasons: they want the color changing capability or they want to divide the area into zones even though it is all on the same circuit.
Or, as @ogiewon mentioned, you can get rid of the smart bulbs and substitute a smart switch.
