Unusual spikes in temperature readings and 4+ hour gaps

[Oleksandr Sukholeyster]

I am using WirelessTag just for few days (hub plus two 13-bit tags). I noticed two issues:

1. There are gaps for 4+ hours between readings, despite 10-minutes update interval is set.

2. There are unusual spikes from 3 to 0.9 degrees down, for single reading (attached). I added "Error Checking" in settings but that did not help.

Where is the tag located?
