I guess I was one of the lucky ones. I know Android versions can sometimes be the problem with certain Apps, Oreo v8.0.0 worked for us. I too read several reviews regarding Android App issues, only issue I had was when I first tried to connect to my ASUS AC3200 router the Doorbell kept announcing "incorrect network password", knowing my router has had this problem with many other smart devices in the past (The 3200 is known to connect to the 5GHz band first on new connections), I temporarily turned off the 5GHz radios on my router so the device would connect at 2.4GHz which then the Doorbell instantly connected. 2.4GHz is better for longer distant between router/device anyway.I have installed many of these and everything worked exactly as designed each time.
As the replacement unit is behaving the same way, most reasonable people would say the issues lie somewhere other than the unit or the app.
The folks here have tried to help you but it didn't seem to take.
And in regards to the amateur-hour wiring installation, why don't you enlarge the hole (like to 3/4" or so) where the bell wire comes through so you can tuck the wire nuts into the newly enlarged space?
I rate this model a 'BUY' because of the features, ease of deployment, reliability, ability to be cloud independent, good apps with instant notficatations and reasonable price.
Right now there are only 2 gaps preventing an 'INSTA-BUY' rating: 1. ONVIF support with 2 way audio in all branding firmwares and 2. lack of a POE interface option.
I agree the App could use some work/improvement but I have to say that not being married to a Cloud service, being able to record locally (SD Card), RTSP feeds and now ONVIF support, way out weigh the minor issues with the App, the App will improve over time. A POE version would be great but as you know it would not be a big seller since few people would want to replace their Doorbell with Ethernet wire, there are plenty of Dome IP Camera POE options with two-way audio out there. This Doorbell is a definite 'BUY' for me.
Question; You mentioned two-way audio with ONVIF, how would that be applied? I thought ONVIF just opens the door for other brands of NVRs other than LaView's or Hikvision that can be used for viewing/recording. I have not purchased a NVR or NAS yet, are you able to two-way through the NVR? Thanks...
