Verify Cellular Signal
When evaluating where to install the ATMOS 41W, METER
recommends verifying adequate cellular signal (Step 3C) for the
chosen location. The cellular signal must be strong enough for data
tobe transmitted to ZENTRA Cloud.
Data Access
ATMOS 41W data are accessed online via ZENTRA Cloud, a web
application used to download, view, and share data as well as to
change configurations.
The ATMOS 41W requires a paid subscription to use ZENTRA Cloud.
See Step 2 to learn how to add the ATMOS41W to ZENTRA Cloud.
Save the orange device subscription card included with the
ATMOS41W in a safe location.This card contains the following
information for the subscription:
• Device serial number
• Password
• Server name where sensor data is stored.

Mobile software and ATMOS 41W firmware.
ZENTRA Utility Mobile will prompt with available updates for
software and ATMOS41W firmware. Consult the ATMOS41W
User Manual (meter.ly/atmos41W-support) for more
troubleshooting tips.
