I have multiple resellers on my network and in the UBNT SM gear there is a box to check off and enter "install date". When I have multiple resellers adding their SM's to my network it's a requirement for them to datafill this parameter. It is not tied to system uptime so I can pinpoint the exact install date for billing purposes. It would be nice if there was a spot to enter this data in ePMP. Thanks for considering this.
Thinking about this I suppose I could have them enter the date under system description...
