Good question @Chappie88! You are able to link your Doorbell to your Smart Light group as well as select a time frame for this rule to be effective. From the Ring app dashboard, open the menu, select Devices, then select your Doorbell, and tap the linked the devices tile. There you should see the light group you created containing the A19 bulb.
Once you’ve selected to link to your A19 bulb, or light group, there will be an option to then select the time frame in which you’d like this to occur. I hope this helps!
