I previously voted on an idea to alert when Meraki firmware is out of date and that was closed as completed and the notes states we could do this with actionable alerts. I don't believe this is the case. You can pull the firmware but then to build an alert you would have to put the specific firmware version and update the alert every time it changed which no one is going to do. There is a firmware status (see attached image) in the Meraki dashboard that I was hoping to get. Please consider adding this.
We've looked into surfacing this information in Roar and unfortunately Meraki is not surfacing that information in their API. If/when they surface this additional information we'll take another look to see if we can provide this data in Roar.
