I had frequent problems with the doorbell going offline and not coming back until I power cycled it. It would happen once or twice a week. I went as far as putting the transformer on a zwave switch and made it power cycle automatically when my stream was interrupted. Since upgrading to the Laview firmware this has never occurred. I just saw this one failure mode once which I think is due to my complex internet failover/aggregation setup which has me have multiple IPs. The local stream seems to always work until the doorbell reloads its wifi module. It apparently reloads the wifi module when it lose connection with the cloud server. I have never had to power cycle my transformer since the firmware upgrade.
Well it is good news about the firmware fixing some of your issue. Bad that you are still having issues. So is it fair to say the Doorbell
IS Dependent on the cloud in order to work? In other words, an Internet connection (to their cloud) is a Must in order for the DB to operate or the DB will reset the WiFi settings.
You know that seems strange as I know we have had some Internet interruptions (downtime), since I have installed this DB and I have not had to touch the DB since install back in July.
Is this a blue battery (CMOS like) in the unit? I remember reading some messages mentioning a battery. Maybe yours is bad? Just thinking out loud...
