The app itself works well—but I cannot pay to upgrade from the free account to the paid plan after my trial expired. I’ve contacted customer service multiple times, changed the country on my account, added a Portugal-based payment card… nothing works. What’s the point of building a good app if customers who want to pay can’t give you their money? Please add a proper web-based payment option instead of relying only on the app store. I genuinely want to pay for Premium—stop making it impossible!

Since recent updates at the device, it keeps looking for WiFi in a loop, gets stable for a couple of minutes and loses signal again. I'm not able to answer with the phone because most of time I get the notification the person/delivery/postman is already gone. It's not a WiFi issue as I have a Vacuum Robot just right there, docked, under this dwelling device and it works just great. By the way this used to work just fine before. It is using 2.4Ghz signal according to router client list by signal.

Hola, necesitamos comprobar si al monitor le llega la señal de 2,4GHz y que no haya ninguna incidencia (puedes estar usando la de 5GHz para el robot aspirador y con el móvil). Para poder revisar tu caso y ayudarte, por favor contacta con nuestro equipo de soporte desde Ajustes → General → Contactar con Fermax indicando el ticket #339964, un saludo.

Takes awhile between someone buzzing the intercom and the app notifying you. Impatient delivery drivers might not wait that long. Half the time the app notification sounds don't work and you might get vibration notification only. Half the time the video doesn't load or the audio doesn't work. Still useful to unlock the door if you don't care that you can't see or speak to the person.
