I’m currently experimenting with the Xiaomi Aqara motion sensor. This has a build-in lux sensor which I tried to use for making the lights go on/off based on the lux-value. I noticed the lux-value is only reported to Homey when there is motion detected. I actually need a sensor which also report lux-value even if there is no movement.
I’ve got my eye on the Neo Coolcam but I can’t find if this is also only reporting on motion or if it’s reporting every x minutes or so. Can anyone confirm?
My Aeotec Multisensor 6 sensors update lux values without any motion. Even better, if powered via USB then I can get them updating values instant even if 1lux change in luminance.
Checked the specs of the Aeotec sensor and on the website there indeed saying “MultiSensor 6 will be able to run in an advanced mode, providing temperature, humidity and light readings in real-time.”
So it looks like that’s a good candidate…
Yes, but my neo coolcam is in the corner of my living room it is a little bit dark, I set de update lux = 3 and temp = 0.1 degrees I used now for almost 5 months and de battery is 87%
On the lux I put the lights on and off in the living room and it works very wel.
What is realtime if it is works what you want.
I doesn’t need to be realtime per se, once per x minutes will be enough for what I have in mind right now.
The main thing is that it needs to report lux also when there is no movement. (Realtime might be a nice touch though).
I think you want a update when de lux is changed, I don’t want a update when de lux is changed, but there is a parameter when the lux is not changed then send the lux value on x time (sec or min) to homey.
I am using the hue motion sesnors for lux measurements.
When lux is below a certain level lights go on.
Works fine.
You can even set a minimal and maximal reporting period in the sensors settings
Flow example and sensor settings (hue sensor directly to lonked homey not via hue bridge)
Lights on by lux (evening).
When: lux changed
AND: lux measurement lower then better logic constant
AND: light not already on (prevents to trigger the flow when the lights are on alread)
Lights on in the morning
When: a certain time (I trigger a virtual device at a fixed time)
AND: lux value is lower the better logic constant
Lights off by lux (morning).
When: lux changed
AND: lux measurement larger then better logic constant+offset (the offset prevents the light to switch on again right after switching of)
Lux value is dependend on a virtual device setting “schoonmaak” when the cleaning lady is in, the lights stay on longer (larger offset)
Settings for the sensor (PS: (ms) should be (sec), thats a typo by athom)
