Best Lux sensor?

I’ll give them another go then with a newer version, think ill put motion sensitivity and the stuff i’m not using down quite a lot to save battery and ramp lux up to changes ever 10 which is the main reason I want it.

I went for the Gen 6 Aeon Labs Multisensor in the end, I like the fact that i can run on USB power for instant always on updates to lux and temperature, id prefer accuracy than battery power.

Fibaro seems awesome. I’ve had it for 6 months, I am checking Lux every 2 minutes and only had to change the battery once. I had the Aeon before and it was horrible (older model).

The example I just looked up for the sensor had then sewing them into clothing. What would be the purpose of that? What can these be used for? What are you using them for in HA?

A lux sensor measure light levels… (luminosity)

I have the Fibaro motion sensor as well and have been very happy with lux and temperature reporting. It took me a while and with help from other members to get good level of lux reporting. But @CyrilPeponnet device handler has made it so easy to work with the device. Also @primarypete was able to help me out with some better lux value settings for option 40 & 42, see below. Hope it helps.

40 = 50
42 = 180

I might pick up another Fibaro as well - I want multiple lux sensors anyway. Will report back on how well or badly the Aeon Labs 6th gen works. If its rubbish i’ll just send it back.

I’ll also compare to my custom built one with the ST Shield and a lux sensor I picked up for a quid on eBay!

Can you tell me how you’ve found the comparisson?

I have many Aeon Labs Multi 6s and they are garbage for Lux. Aeon said straight out that if the light isn’t directly falling on them then they are wildly inaccurate. I was excited since I wanted them for motion. So disappointed.
Did you ever try another Fibaro?

I am quite happy with my Aeon Multisensor 6. Mine has been reporting Lux well. I wanted something that wouldn’t need batteries, and I have that now.

I know this is an old topic however still not happy about the Lux sensors out there. However I found this recently, might start another thread on this if worth it.

Wireless Tag ALS

Anybody try this Wireless Tag ALS device? From the description it can trigger IFTTT on sudden light changes or thresholds which is perfect and flexible for all the needs. Although you do need to purchase the ethernet to connect to your wifi, it’s still seems the best so far I’ve seen. Any thoughts?

One painful issue, is there a way to view the triggers/actions of a service on IFTTT before buying a unit? Hate to spend the money and find out the triggers/actions are not what I needed. Seems to be an ongoing issue for me for many products that require purchase to create an account.

What is it you are not happy about with existing Lux sensors? I’m effectively using a ZooZ 4 in 1 Motion, Humidity, Illuminance and Temperature Sensor. It, along with webCoRE controls all of my lux-driven lights in my house.

For my ‘Gloomy Lights’ piston, I have selected lights set to turn on at a low lux-level threshold and back off if the ambient lux-level rises above a high-lux-level threshold that is 15 points higher than the low level threshold. I’ve also added in timing buffers so that the lights aren’t flipping on and off.

Anyway, what is it that you dislike about existing Lux sensors?

Haven’t looked at the ZooZ sensor. Thanks for sharing your example. That maybe an option.

Basically many of the sensors were difficult to get a trigger off of thresholds to create actions with ST. Seems like this one will do it.

I’m a bit confused. All sensors are capable of sensing something (Lux in this case) and then exposing that reading for use with ST. That’s pretty much it. The Sensor isn’t going to do anything with the readings or thresholds itself without ‘help’. In my case, I’m using webCoRE to read the current Lux reading from the Sensor and taking actions within ST. Depending on what you’d like to do with the Lux reading, you might be able to use the Smart Lighting app. It’s not as flexible or as capable, but it may work for your use case.

In short, any reliable lux sensor will read and expose lux levels. You’ll then need to use another tool (webCoRE, Smart Lighting, etc.) to do something with the readings.

Have I misread your intent? Let me know. Maybe I can help.

Thanks lflorack, that’s good insight for me. I do understand most all sensors have some light sensor built in but getting those values you need the “help” of some tool like you mentioned. SOmetimes not easy to find or maybe I haven’t discovered enough of them.

I ended up using an old Android device (old phone) and used Tasker which can read light level from the phone. Used that to trigger SmartTools- >ST and now it works good enough for my needs.

Lux/luminance can be used in Smart Lighting rules as a trigger.

@Benji,. Just saw that. Very nice. Now need to find a sensor Smart Lighting detects for illuminance. Currently none of my sensors are listed. That or change a device type or hack a DH.

A sensor can only read LUX levels if it has the hardware needed to read LUX levels. A DH, hacked or not, can’t overcome a lack of hardware.

Yeah your Zooz sensor should be a good example of this! Question for you @lflorack, is that sensor running locally or do you have a custom DTH on it? How long is the latch time on motion?

It’s not running local. I’m using the custom @RBoy : ZooZ 4 in 1 Motion, Humidity, Illuminance and Temperature Sensor (Enhanced) DTH. It works very nicely.

I didn’t know the dead time after motion because I only use the LUX portion of this sensor. So, I just checked it and it’s about 1 minute and 20 seconds. The biggest advantage of this sensor (for me) is that I was able to(fairly easily) hardwire a power supply to it. I never have to worry about batteries for it.
