I have 3 Ikea Vallhorn motion detectors using ZHA. What I see is that all 3 have a max illuminance value of 1365 lx and give a straight line in the graph until it declines at the end of the day. Anyone experiencing the same odd behaviour and is there a solution to display the actual (high) illuminance values?
I suppose you want the second one ?
No idea how to on ZHA.
I only have 1 illuminance value in ZHA for the Vallhorn. And it is topped of at 1365 lx
Same here, also using ZHA.
Same for me on the two devices I’ve bought. The limited range didn’t really fit my usecase so I tinkered a bit. I found that applying some tape over the circuit board at the location of the ligt sensor and increasing the calibration value in the Z2M results in a sensor with a measuring range between 100 and 15k lux.
