Ok - I have been trying everything to get “Do not disturb” to work with the Eufy software. What I have found MIGHT be the problem. There is a setting screen on the phone (Samsung s23) called “Do not disturb permission” under special access. I can only get there if I search for “disturb” or “special” in settings.
The Eufy application is NOT on the list of apps to be allowed this permission. Perhaps this is the problem that many have posted about?
