Security light and smart bulbs
Your control systems are incompatible

This is one we see all the time.  People try to dim their remote controlled fan.  Or a timer with a motion sensor.  Or get their modern era smart switch to play nice with a series dimmer in 3-way mode.  

Bottom line: one thing must control the light.  One thing.  It must be the master of the light.  And then, other things which are compatible may interact with it, if they are compatible.  So for instance a smart dimmer that supports compatible remotes, and then, a compatible remote.  

And if you need to glue a bunch of crazy contradictory control methods together, then you need to use smart-home/Internet-of-things technology.  Like a Wemo or Alexa hub.  Then, you install each control method so it talks to the hub, and write software code to define what each control does in each existing condition.

In your case, you need to tear apart that motion sensor kit (motion sensor + lamp stalk combo) and replace the motion sensor with a motion sensor that talks to your smart home platform.  Then, you define in software "if motion sensor detects and not daylight and light not on, turn on".
