Oooo what a great nightlight for the hallway or the kids rooms.
How do I submit a driver request?

It already exists. "ThirdReality Multi-Function Nightlight" looks to be the one for this.
That just sounds like another point of failure to me, and something to eat cpu cycles before firing an automation. That said, I do use outside lux readings from the average of 4 Hue outdoor motion sensors in some indoor lighting automations. It is much nicer than basing everything off of time of day.
I'm using the Matter version (https://www.amazon.com/THIRDREALITY-Matter-Multi-Functionality-Compatible-Google/dp/B0CGQYQFNV) in various places throughout the house to solve range issues I was having with trying to extend my Zigbee mesh. All three things (motion, night light, and lux) work really well that I'm planning more to finish out my needs. I know others have used the Zigbee version and generally enjoy them as well. Let me know if you have any questions about the device itself as both versions work the same.
As for your question, I use the lux sensor on the device in a couple of my rules related to when someone comes home and what to do with the lights. Basically, if the lux is under 175, turn on the lights in the drop zone and kitchen. Very simple rules that work well.
There is also this thread (Night Light) that gives some background when the driver was first released.
I am using a inovelli 4-1 as my lux sensor and I use this to set my Mode throughout the day.
All of my motions rule for the main floor and upstairs use mode as a required expression so none of them fire during the day.
My use case for the illuminance sensors is to (obviously) control lights and curtains/shades.
Can you explain more on how you use it to control your shades? Where are the lux sensor(s)? Outside or inside?
I also use Illumination plus sunset/sunrise to set my modes: morning, day dark, day bright, evening, night.
These modes determine lighting and levels in all rooms.
I am using my Tempest weather stations Lux sensor. You can call the Tempest through many custom integrations found here on the forums. I use the UDP/WeeWx/MQTT/Hubitat integration for real time updates with no cloud.
I set up two variables "Lux Low" "Lux High". The values are separated by about 200 lumens. When below Lux Low the background lighting in the home will come on, when high the background lighting will turn off. I also use the lux in a few automations such as occupancy in my office, if it's too dark out and I enter my office the work lighting will come on. It will not turn off until the room is non-occupied.
What is great since we have storms that come through in the middle the day in spring that darken the sky the house is always in a state that make it feel well lit.
All lux sensors are facing outside through the glass. This way they are all like outside lux sensors.
There is a separate sensor for each shade/curtain. The way how Sun moves single sensor is not enough. Here is an example of one rule:
I thought using the lux from an outdoor weather station was unnecessarily complicated but I see the advantages now. The biggest one is that you can use one sensor as a lux measurement for all rooms exposed to windows with no influence from interior lighting.
It depends on the type of weather station. But what I found is that I had a lot of options with the Tempest (Poll API, WebSocket, etc.) Once you have connectivity there are a lot of data that you can use in the Hubitat, Lux was the first sensor I used for lighting.
Thanks for this and posting your rule! Very helpful. Which sensors are you using for this, looking for something discreet that I could tuck up and stay hidden if possible.
Hi
Im using the aqara mijia light sensors. They are small, magnetic back, battery life is years, rock solid on C7 for years.
Bunch of Xiaomi Mijia GZCGQ01LM (I guess, the same as described by @zsolt.toth.39).
But these are not available anymore (too bad).
Alliexpress has them. Do they pair up directly with hubitat or do you need a separate hub?
zigbee they are. Has mijia drivers for them. they work alright, So , direct
I use a Hue indoor motion sensor setting on a window sill facing outside to the west to control my west facing shades. It reports illuminance without motion. With significant overcast cloud cover the sandes do not go down. Above x lux / illuminance is a required condition for the shade rule to run. I use a separate rule for shades up at sunset just in case we manually operated the shades and the required condition will not have been met to start the shades down rule.
