I have a LTS doorbell problem. Everything works as expected with Blue Iris however when the doorbell looses wireless connectivity it issues one ding at any time night or day. My wife and I have just about got to the point where we ignore the doorbell and are about to remove the doorbell from the system. It stays disconnected for about 30 seconds then reconnects and works normally.
I had the same problem. Only mine would reboot over and over and almost always it was between midnight and 2-3am. And it would reboot loop about 6-8 times, dinging the chime each time, and then finally connect. It would did this at least 2-3 times for 2 weeks. Needless to say, I stopped that crap! I have now replaced it with the RCA 3MP doorbell camera which is much improved and easier to set up BUT I have been having undervoltage issues and am presently chasing that. It clearly needs more power than the old doorbell and I have upped the voltage from 16V to 24V and still am having undervoltage issues (thinking I might need to go higher than 24V 20VA). Still trying to figure that one out and still have my mechanical chimes working with it.
