Does anyone happen to have an actual FIT access point (preferably connected to a local FitController, but not sure that's strictly necessary)?
I've been tinkering tonight with my newly acquired EWS850AP and try to convert it to an EWS850-FIT and register it in a local FitController I have running under Proxmox. I think I was able to convert it and get it flashed with the EWS850-FIT firmware (it now shows as EWS850-FIT in the web UI, however the overall skin of the web UI is the same as it was under EWS850-AP, so I'm not 100% positive).
However, I've hit a stumbling block in that the controller seems to reject my device's serial number when I try to register it. I'm wondering if maybe actual FIT devices have a certain serial number format that the controller validates against, so I hope to be able to get someone else's legit FIT serial number to compare to so I can figure out where to go from here.
