Tag manager going offline, water(moisture) sensors reporting out of range and PIR (false alarms)

[Keith Frank]

I have placed two separate orders for tags and tag managers.

My first batch order number(#7574) was ordered on 08/18/2015

I have had two issues with the items in this order

1.The PIR KumoSensor has been reporting a number of false positives for motion events every day. I cannot find a sensitivity setting in the interface so I assume there is none. This sensor will also occasionally report out of range until it is manually triggered.

2. The Wireless Water/Moisture Sensor reports "out of range"  all the time but will trigger if the sensors are wetted or jumped with a metal object

The second batch order number (#7991) was ordered on 10/07/2015

The issues I am having with the second batch are as follows:

1. One of the tag managers(there were 2 in this order) keeps going offline and has to be rebooted manually (unplugged and plug back in) to be brought back online. This is happening every 24 to 48 hours.

2. Both of the Wireless Water/Moisture Sensor are behaving exactly the same as the sensor from my first order (reporting out of range) 

3. The PIR KumoSensor has been reporting a number of false positives, the same behavior as described in the PIR Tag above.

Could you please advise on how I might resolve the above issues?

Please return the PIR sensors for replacement. We will email you a return shipping label.

As for the water sensor out of range, I logged into your account and found that you are grouping 3 tag managers together and there seems to be signal overlap (i.e. some tags are reachable from multiple tag managers at the same time). This is not a supported way of using the grouping feature. As you see when you click "Add tag manager" button: 

"When a tag manager is grouped with another tag manager, they share the same list of tags and radio ID. Up to 255 tags are supported in one group no matter how many tag managers are in that group. A tag may be out of range from one tag manager but responding to another. This is useful when tags need to moved from one location covered by one tag manager to another location covered by another tag manager, or when replacing a defective tag manager with a new one, without having to re-associate each tag. NOTE: Signal coverage of multiple grouped tag managers should not overlap." 

To use multiple tag managers to cover wider area, first check if one tag manager is enough (the range is often better than you expect). For tags that are out of range because of signal strength problem (signal level < -95dBm) unassociate them and associate it with another tag manager ungrouped, and preferably configured at a different frequency (configure frequency from settings->wireless).
