Thanks for the report. From the config, the device looks like it was created as asistente (the secret names still carry it) and renamed to assist later. A few questions so we can pin this down:

1. Where exactly do you change the hostname each time: the "Rename hostname" dialog, the "Device IP or hostname" field under Install, Advanced options, or by editing name: in the YAML?
2. When you renamed the device, was it online at the time? Did the dashboard build and install new firmware as part of the rename, or did it only rename the file (the offline confirmation dialog)?
3. What does the dashboard show for the device right now, online or offline, and does it also appear in the discovered devices list under the old name?
4. Which hostname does the device actually answer to on your network: ping asistente.local or ping assist.local?

If the rename happened while the device was offline, the firmware on the device keeps announcing the old name until it is flashed once, and the dashboard keeps seeing it as offline under the new name. In that case a one time install with the old hostname or IP typed into "Device IP or hostname" under Install, Advanced options should bring it in sync permanently; please tell us if it does not.

1. 3 dots then rename hostname
2. yes, but the dasboard didnt do anything, just the filename changed
3. then it said offline, but when i renmed it again it said device offline, sure you want to change it, and when i clicked yes it said online
4. ping assist.local
