I have two of the Zooz that seem to work well. They are a bit expensive and the batteries die even if you have it plugged in.
I've just ordered the Tuya Zigbee sensor discussed in this thread. Less than 1/2 the price of the Zooz, and reportedly the battery does not discharge when it is plugged in. Will post in this thread once I get it. If it works and the price stays low, I'll order more.
