all my motion/temp sensors are the new Samsung Multipurpose sensor (blue box)
I use them with various doors (using the magnet), in my garage (without the magnet, just the tilt sensor), in my fridge (magnet). All are reporting temperatures nicely.
About the washer, after reading various posts, I preferred NOT to use the sensor for checking vibrations (because a lot of cycles are generating vibrations), but I'm using a Zooz Zen15 to monitor the power used by the washer, with 100% positive results and no errors.
Obviously, you can use both to fine tune your cycles and obtain good results.
Read this (or search for washer app). Somebody did a specific app just for that purpose:
And now I have a dashboard tile just for that washer, including power use and time used by the last wash. Of course, cellular and GH reminders when finished.
