looking at the documentation for the Support Assistant Primelink devices are not listed. If you look on the details of the app in the gallery. Select the additional support and open a ticket with the Support Assistant team directly. They might be able to tell you if they are planning on supporting that device or not.
We have a customer with a PrimeLink and we installed the Support Assistant 3.0 app on the device. It displays the following error when trying to use it.
I can confirm that the following settings are set on the device
SNMP Port Status is Enabled
SNMP v1/v2c Protocols is enabled
Allow Write is enabled
Community Name is public
Trap Community name: SNMP_trap
Is the app compatible with PrimeLink devices?
