My keypads are all showing 00/00/00 00:00.
I have rebooted both ElkM1 Gold and Ethernet. I checked that the time server is working. I also set time from my PC. Finally I rebooted again, by powering off ElkM1 and Ethernet, waiting 10 seconds, and powering on.
Firmware versions: ElkM1 5.2.10, keypads 2.1.48, and Ethernet 2.0.34.
I don’t know what else to try.
Possibly related, last night I had a false alarm (dang robot vacuum ran while we were not home, sigh). When we got home the alarm speaker was “clicking”. I did the power off sequence mentioned above, which seems to fixed the clicking, but the keypads all have 0 as their time.
Just wanted to add that in close to 18 years this system has always been rock solid. I’ve never had to reboot it because of a problem.
