I’ve been struggling with this for a while. Everything else seems fine (motion, humidity, temp) but the light readings are super low. The range for the light sensor is 0 to 30,000 lux, and I have my lights on full whack at the moment and its reporting 13 lux (consistently).
I’ve tried forcing a few parameters but nothing seems to help. Has anyone had a similar problem or know how to fix?
I’m having the same exact problem with my USB-powered multisensor 6. I’ve set parameter 43 to 1, and also set 54 (the lower limit value of Lighting sensor) to 0, and it just never updates, and sits at 7 in a fully-lit room during the day. I finally shined a flashlight directly at it from a few inches away, and it still didn’t update, until I manually pressed the wake-up button. Then it finally jumped to 921. I turned the flashlight off and waited. 10-15 later it finally dropped back down to 7.
I paired the device on battery initially, but then deleted and excluded it and paired it on USB. It’s been plugged in via USB ever since. Since I bought this thing for the light-level monitoring, how do I get it to actually be useful?
OK. Selecting reporting parameters 41-44 require that 40 be set to “1”, so that may be why your 43 is not working as expected. Similar for 54… it requires parameter 48 be set, but that’s a bitmask, so to turn on all high-low limit reports you would set it to 255. By default these are both 0: reports off.
Parameter 40 did the trick! I must have just assumed it defaulted to 1 when I was first reading through all of the parameters. Thank you!
Of course, I don’t know why my light levels are reading so low, unless my lighting in that room is really just that bad. I didn’t exceed 30 Lux, in the middle of the day, with the curtains open and the lights on. Is that really normal for indoor readings?
