Pretty sure if you performed a factory reset you should not be able to remote login with a browser until you activate with the app? Make sure you delete the doorbell completely from the app before trying to activate it again. I think I recall this happening when not deleting the device from the app? I've had instances when resetting the doorbell having the app say failed to connect or the counter times out only to find out it logged into the Hik server. When resetting I think you you have to hear "Start configuring WiFi" and then "the device is registered" or "the doorbell is running" or something along those?
I tried resetting it, turns on, says the doorbell is running, then connection failed. The device is completely deleted from the app. I then go to set it up, I run through the setup, it connects to the wifi, then it says activate, I set a password, but when I click activate it says activation failed. Afterwards, I can access the doorbell via the browser but it won't add to the app or hik connect or anything
