Zooz 4-in-1 Sensor

[viprush]

I had the same problem with the motion sensor not appearing with the Zooz 4-in-1 sensor and solved the problem by rebooting the hub.

The illuminance levels reported by the stock HE Zooz driver maxes out for me at 53 (middle of a bright sunny day, positioned right under a skylight). Is this a correct value? My log shows some compressed lux value reporting. I set the reporting interval to the smallest available. Can anyone help me get better lux values from this senser?

Here is the data capture:

Yes, the lux sensor of this device reports 50ish as it's max, this is a hardware limitation not HE or driver related.

[mike.maxwell]

This device reports light level from 0 to 100 percent, we mapped that into lux, since 0 to 100 makes no sense in any part of this earth...
If you're actually interested in a ledgimitate value, you'll need a different sensor.

[walksonair]

Thanks for the response. What's the units of lux you mapped to? Is there a logarithmic conversion that's being done in the code?

[halfrican.ak]

I believe the driver code interpolates the 0 to 100% value the sensor reports to a "lux" value of 0 to 50 (ish) which is what the 0 to 100 percent is equivalent to.

The sensor can only measure up to 50 (ish) lux in it's firmware

[walksonair]

Thanks very much for that info! I didnt register the max lux being firmware limited...I wonder why.

I used to use the SmartThings Weather Station which was my go to for LUX values. Even now after sunset, the weather station reports 10lux (for a partially moon-lit night).

Does anyone have any recommendations for another sensor that may be more suitable? I do need humidity and luminance. The monoprice Product # 15902
appears to be a white label Zoon.

[halfrican.ak]

I've used both the dome dmms-1, fibaro multi sensor, and the aeotec multi-sensor. They all report lux up to the mid 30k range.

@walksonair

I wonder why.

Personally, there can be only one reason for this.
Which is having no concept of the potential use cases.

[halfrican.ak]

My guess would be an day/night scenario but 50lux is still pretty low for that

Has anyone figured out how to change the wakeup internval? Per a Zooz support page it is customizable.

"While your 4-in-1 Sensor's wake-up interval is set to 12 hours by default to save on battery, you can adjust this interval to better suit your needs or force wake-up when necessary."
