Hello,

I am using the Aeotec ZW074 MultiSensor Gen5 (outdoor sensor) with Domoticz. I have some trouble in understanding the parameter settings. For instance it says:

Code: Select all

43. Luminance Reporting Threshold: 
25600
 (LUX) (aktuell: 25600)

Threshold change in luminance to induce an automatic report.

I do not fully understand how to do the math here and what the 25600 means.

For the next I think I get it a bit:

Code: Select all

2. Humidity Reporting Threshold: 
1280
 (%) (aktuell: 1280)

Threshold change in humidity to induce an automatic report. Note: The accuracy is 0.1. The high byte is the part of integer, the low byte is the fractional part.

If I translate 1280 to a hex number it's 500. Does that then mean that at a change of 5% the report is sent?

Still for the luminance parameter that would be 25600 (10) = 6400 (16) and I can't imagine it means 64% change!?

I would be very glad if somebody could come up with some clearer explanation. Thank you!

EDIT: here's a link to a manual for the sensor: https://support.smartthings.com/hc/en-g ... manual.pdf

Yet, it doesn't help me better understand the 0x6400 value (why is it 100 LUX?). The 5% guess above seems right.

I also have the Aeotec ZW074 MultiSensor Gen5.

The intention is to use this sensor in the bath room to switch on the fan when the humidity is too high.
Sensor is included properly, but updates rather slow on a steep increase of temperature/humidity because of taking a shower.

Can someone help me to explain what is meant for the next settings (41, 42 and 43?

Code: Select all

40. Reporting Threshold:

Enable/disable the selective reporting only when measurements reach a certain threshold or percentage set in the threshold settings. This is used to reduce network traffic.

41. Temperature Reporting Threshold: (%) (actual: 10)

Threshold change in temperature to induce an automatic report. Note: 1. When the unit is Celsius, threshold=Value. 2. When the unit is Fahrenheit, threshold=Value*1.8. The accuracy is 0.1. 3. The high byte is the part of integer, the low byte is the fractional part.

42. Humidity Reporting Threshold: (%) (actual: 5)

Threshold change in humidity to induce an automatic report. Note: The accuracy is 0.1. The high byte is the part of integer, the low byte is the fractional part.

43. Luminance Reporting Threshold: (LUX) (actual: 10)

Threshold change in luminance to induce an automatic report.

41: why is the change in temperature mentioned in percentage instead of 'C? What if I would like to receive an update with each 1 degree C? What value do in put in there?
42: I would like a humidity report for every 5% change of humidity. Is '5' the right value, or should it be 5.0?
General: what is meant with:
- threshold=Value
- The accuracy is 0.1
- The high byte is the part of integer, the low byte is the fractional part.
