I am looking for the “best” sensor that works with SmartThings that can reliably detect motion and light level in a bathroom with a window. Humidity and temperature are bonuses, but not required.
I just installed an Aeotec Multipurpose Sensor 6 and the experience is quite disappointing. It has been fluctuating between “Motion” (99% of the time) and “No Motion” (1% of the time). Once it goes to No Motion, it goes back to Motion state within about 2 seconds. The other sensors report 79.5°F, 57% humidity, 10 lux, 0 UV index, 100% battery, tamper clear with no change whatsoever. Bear in mind that those values were reported even when I took it outside and left it directly in the sun for 5 minutes, brought it back in, closed the blinds, moved it between rooms, turned on the shower, etc.
I have a boxed Samsung SmartThings Motion Sensor 2018. I know it would work well because I have had another one for 11 months that is just the right sensitivity, and never fails to report until the battery dies. However, the Samsung SmartThings Motion Sensor 2018 is a one-trick wonder and does no light level detection.
My tolerance for playing with sensors like this is low. They do not have to be all that accurate for scientific measurements, but a consumer should just be able to buy a sensor and have it work more-or-less out of the box, without needing to resort to lengthy troubleshooting for a $65 product.
The Aeotec Multipurpose Sensor 6 is currently being powered by two rechargeable CR123A batteries that are fully charged. I read that the sensor is much more reliable with a dedicated Micro USB power source, but I am simply not willing to go there when the product (and its competition) are supposed to work on batteries in the first place.
Should I get a separate light level detector, or a different product that can do both reliably?
