I can't connect it and I don't know how to connect the doorbell to the internet
★★★★★
I was pessimistic after all the negative reviews but was pleasantly surprised when this worked out of the box exactly as intended. No issues.
★★★★★
Great! But it doesn't give me enough time to answer manually or through the app.

Connection is terrible. 😠 By the time you open the app, and try to answer intercom, the person has gone.🙋♂️ The camera at nighttime is practically impossible to view.🥸 Very disappointing, as we have used alot of Fermat intercom's in the past 😔
★★☆☆☆
Bought Fermat Wi-Fi earlier this month and so far haven't been able to receive any call on mobile. App still not working as of today.
★★☆☆☆
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!
★★☆☆☆
Painfully buggy! Besides this app, the home system needs to be restarted once a month (you need to rip the monitor off the wall!). Often you cannot open remotely (isn't this the whole point of this app?), then you'll get ambiguous error messages like "Error sending Auto On command" (??) Even if the app works it lags 10–15 seconds until you'll get the call to your phone :(Even contacting support does not work!! (Settings - General - My Account - Contact Fermat - ERROR!)
