Hi, I tried running the below API call however in the output i see some weird RSSI values. Can someone confirm me why do i see this '0' values ?

API call -https://api.meraki.com/api/v1/organizations/{{orgId}}/wireless/roaming/byNetwork/byInterval?networkIds[]=XXX&timespan=3600

A value of 0 does not mean 0 dBm, it simply means Meraki had no usable data for that moment.

So how do I interpret such data? if it is a good or bad roam? because I see lots of clients with same '0' value.

That doesn't look normal. Are you using a recent firmware version ? I would reach out to support , early access API often have bugs

I think that to evaluate roaming quality, you can use the following criteria:

duration: <150 ms = good
rssi.after: >35 (-65 dBm) = good

Yes, APs are running on 31.1.8 Firmware and APIs was taken from the Meraki Documentation.

But if it is after then it means client has already roamed right. so, I think it is good to monitor both before & after.

I understand that Meraki defines it as 0 when the AP does not have a valid measurement, which in this case is common and normal in fast roaming.
So I think the correct way would be to use "after" protocol and duration to assess roaming quality.
