Include Active Items tag

Publishes the ActiveItems tag which is the count of the total number of tags on this device.

Include Barometer tag

Publishes the Barometer indicator.

Note: The communications barometer represents the marginal success rate of communications. For each poll cycle that does not receive a response for one or more poll messages, the barometer will increase by two (2), with a maximum value of 100. For each poll cycle that does receive a valid response for all poll messages, the barometer to decreases by 1, with the lowest value being 0. These barometer changes cause failures in communications to show up quickly as the barometer rises. However, good communications must be maintained longer and more steadily for the barometer to fall back to 0.

Include Comm Status tag

Publishes the CommStatus tag which represents the status of the communication link to the device.

• The value will be 1 if a communication link to the device can be established – even if the device does not respond to polls.
