Problem
Corrective Action
“Status – Good” posted in plumbSMART and faucet actuation
event data not appearing in plumbSMART (< 2 hours) or
“Device Not Communicating” warning or severe alert posted in
plumbSMART for all devices (> 3 hours)
Step 1
Verify gateway Status LED flashes twice every 2 seconds. If LED
is OFF or ON solid, power cycle the gateway and wait for no
more than 5 minutes for unit to initialize and connect.
Step 2
After initialization is finished, LORA LED should turn ON solid
within an additional minute.
Step 3
If LORA LED does not turn ON solid and ethernet cable
connected, contact facility IT administrator to modify port rules
to allow Zurn gateway to access the internet via local router.
If gateway model is ETH/LTE, visually verify SIM card is installed
in designated slot on the side of gateway. If unit has a SIM card,
then disconnect ethernet cable and power cycle the gateway
and wait for unit to initialize and connect. LORA LED should
turn ON solid after initialization.
Step 4
If problem still present, move gateway closer to LoRa monitors
and/or verify gateway mounting, orientation and connections
comply with requirements listed in Zurn Gateway Installation
Guide.
