Hi alemabrahao,   i contacted support Meraki team and i opened a case. Below Meraki support answer: Today this feature is not  implemented. Greetings Stefano Thank you for contacting Cisco Meraki support today. Yeah as you've mentioned, At the moment it seems that it can view who has confirmed access only if the client is online. Unfortunately, this is not a supported feature at this time.  Although this feature is not available, we take our customer feedback seriously. We encourage you to use the Meraki dashboard to "make a wish" and submit a feature request. You can submit a feature request at the bottom of any dashboard page. Any wish that is made sends an email to our Product Managers and Development Teams. These wishes are taken into consideration and are used to help shape our product roadmaps. The most wished-for items are incorporated into product development. Please do let me know if you have further questions. I will set this case to close pending this means, if I haven't heard from you in 3 days the case will be closed, however, if you have any questions you can simply reply and the case will re-open automatically. Have a great day! ... View more
