Maybe you can try using my 
Sensor Light blueprint.
You would then create a schedule helper, ON at 7am and say OFF at 10am, then also ON at 3pm and OFF at 10pm. Use this as the trigger.
Then use the Ambient condition and set your lux values.
Now if it is 7am and it is to bright it will not come ON but if your lux is below your Low Lux Value the light will come ON. Once it goes above your High Lux Value the light will turn OFF.
In the evening the trigger will be ON at 3pm but if your lux value is above your Low Lux Value the light will remain OFF. When the lux level drops below your Low Lux Value as it gets dark your light will turn ON and then at 10pm your light will turn OFF.
You could also use the Sun Elevation but if your using your LUX value it should work well.
One option you must use when using the Ambient Condition is to make sure you select NO - My Ambient Light Sensor is not affected by the Lights so the High Lux Value will turn your lights OFF. However if your LUX reading is effected by your light then maybe consider just using the sun elevation condition and not your Ambient Condition. If you keen to use the Ambient Condition then it is good to have a outside lux sensor that reads the lux values and is not effected by any lights in your house. You then can use that lux sensor for all your automations.
Hope this helps you.
