Which luminance and temperature sensor do you use?
[ moderator edit for reference: moved from the ‘shading automation’ thread, it is about outside use. ]
Moved your post as the examples section is not for discussion.
I have Aeotec and Fibaro ZWave sensors.
If I was able to start over I’d make sure I get a sensor that does not top out at 30K or so lux.
Unfortunately, almost all smart home sensors do as those are quickly reached on summer days, even with some clouding. A clear sky summer day has 100K lux.
I guess I’d go with ZigBee this time, the Aqara is said it can do 100K. Hue too, eventually.

I use Xiaomi Aqara sensors. No issues so far.
If you have an IoT-camera, it also might be able to provide you with current lux and maybe even temperature values.
I have a mobotix camera which triggers openHAB when lux values goes below a reference value
I use an enocean Multisensor made by Eltako. I like it a lot.
The MS multi sensor sends the current weather details, including
brightness (from three points of the compass), temperature, wind,
rain and frost (including heating of the rain sensor).

But the aqara sensor is a proximity sensor and only works when someone is near, not posibly always, rigth?
I am planning to program one with Adafruit VEML7700 Lux Sensor - I2C Light Sensor : ID 4162 : $4.95 : Adafruit Industries, Unique & fun DIY electronics and kits and a esp8266
No. It has a motion detector as well but that is independent of the brightness sensor.
Then why did you ask in the first place ? It’s not fair to waste people’s time.
You are correct that it has both sensors, but the lux values only update when motion is detected or after a long frequency (but not even sure on that, mine update usually via motion).
Can be a benefit (i.e. lights only turn on when someone is actually around) or limitation though.
Edit: here some documentation about it, frequency seems to be about once per hour
Oh sorry, right, I confounded that with the Aqara. I meant this one.
The Aqara one has a maximum of 1000 lx so it’s unsuited for outside use.
Does it work with the ZigBee binding for you ?
I have moved over to deCONZ, so I cannot really tell.
I’ll second the Aeotec- I have 3 of their Multisensor 6 units but I only capturing luminescence from one to automatically turn on or increase the brightness of a lamp when motion is detected (so I’m also using the motion sensor on the same unit). No issues at all since I got it in 2019.

I have both an Aeotec multisensor and an Enocean ElTako light sensor.
A really good sensor that do survive blizzards, rainstorms and do work in more extreme temperatures is this one:
For the price one get a sensor that is made for outdoor use.
Even comes with stainless screws.
The MS 6 is a good indoor sensor as long as it is USB powered.
