Product review (1 stars): this device "drain" batteries every 7/10 days
I have to review my comment to this product. Unfortunately.

I had an initial problem to set up the sensor, as seems to have a neighbor with the same pack, which makes difficult to make the main device to read the right sensors. but it is minor and I could figure out for the first setup.

After the first week it becomes weird, because the main sensor literally has drained 3 batteries. At the first moment I didn't realize, replaced the batteries, and moved on. After this every 7/10 days, I have to replace the batteries, because they gone fast. I am always use new batteries.

And after the first setup, I gave up to setup my sensor A - the same my neighbor has.
