Hi,
been a hectic couple of days. Tuesday morning, power pole transformer exploded and somehow dumped excess voltage on my phone line which is my back up DSL internet connection. The smoked the phone socket, the BT Home Hub and parts of my UDM PRO switch (and possibly more) are damaged.
The UDM PRO switch runs, but does not communicate with other devices but did not report any errors either. This router uses POE to power the WiFi and a HA Yellow.
After several attempts, I was able to use my 24Port POE switch and a Teltonika router to restore basic functionality.
Currently no vlans, no firewall, no local DNS, new IP addresses, same Wi-Fi SSIDs.
The HA Yellow started and got a new IP address. It connected to and controls the ZHA devices.
Several services need some manual intervention.
e.g. SONOS - delete and it the rediscovered the speakers.
Synology is more of an issue. It used to have a FQDN which was resolved by the UDM PRO. Now the NAS cannot be pinged via the FQDN. The FQDN is needed for the certificate that protects the connection.
Is there a way to add a hostname to HA Yellow?
I tried vi /etc/hosts, but there is no vi command, nor dig, nor nslookup.
regards
