Reviewed in the United States on March 16, 2025
I will update this review if and when progress is made.I purchased one WT901SDCL-BT50 through my company for preliminary equipment monitoring use. So far I can't connect to the sensor at all. There are LEDs on the sensor, but no explanation of what those are. So I don't even know if it is powered on. I only get one red LED while connected to a charger. My biggest complaint is the company maintains a google drive called WITMOTION Document Center, and there is zero info for this model.
