4.0 Application Setup Example (continued from previous page)
7) Go to the iDigi Dia web UI. This will be your gateway address followed by
/idigi_dia. See figure to the right. Note: you must have the output drivers in
the yml file as shown in Appendix B. An alternative way to obtain status
messages is to enable the dia setting log_status: 'true' and view the
status_log.txt file stored in the python files web UI. This setting stores the
status information of the latest record of the automated message.
8) The RF signal strength report is named “radio_strength”. If it is Moderate,
Strong or Very Strong, then your gateway is mounted in a good location. If a
report of “Weak” is reported, then review Appendix C for placement
strategies. In some applications, you may have to move the sensor or place a
wall router between sensor and gateway.
9) If your application requires security, you may program it as follows:
a) Obtain the dia.yml from gateway
b) Set xbee_security_enable: 'true'
c) Set xbee_security_key: your value
d) Repeat for all sensors in the dia.yml
e) Boot gateway and wait for all sensors (depending on your current sleep setting) to be programmed with the
security enable and keys.
f) When all sensors have been programmed, update your gateway’s XBee with Encryption enable (EE) = 1 and
Link encryption key (KY) to save value you set the sensors. Click apply
g) You will have to wait until sensor wakes up from its programmed sleep for it to re-associate with the
gateway. If your sensor’s sleep interval was programmed for 0, then you will have to wait up to one hour to
re-associate. If sensor sleep setting was non-zero, then upon the next wake up cycle will it re-associate.
The gateway can be set up to route the sensor status
information received to a server or cloud storage such as
iDigi. Hosting sites can obtain and mange your data that
could include sending you notification on tank level,
alarms, and such to your PC or mobile device. For more
