Software issues / False reading - no Cat their repeatedly or not letting our cats in
We’ve had problems with the OnlyCat cat flap pretty much from the start. After setting it up, everything seemed fine, and we successfully linked our cats’ microchips. However, the flap initially refused to let our cats in or out. Thankfully, this was eventually resolved after contacting technical support.
Things then worked brilliantly for around a month, and we thought we were finally sorted. Unfortunately, the problems started again. The cat flap began constantly detecting visitors every 1–2 minutes, even when there was absolutely nobody there. It was as though it was detecting ghosts!
After contacting technical support again, the team installed new firmware, which appeared to fix the problem for a day or so. However, the issue soon returned.
Now, we have the added problem of the cat flap failing to recognise our own cats when they want to come inside. They can be pushing against the flap with their heads and paws in exactly the position where their microchips should be detected, yet the flap still doesn’t recognise them.
It’s incredibly frustrating to have a product that works one minute, stops working the next, constantly detects visitors who aren’t there, and then fails to recognise the very cats it is supposed to let in.
We have contacted customer service multiple times, and whilst we appreciate the help from the technical support team, we still don’t seem to have a lasting solution. At this point, I genuinely question whether there are significant firmware or software bugs affecting the product, as the issues seem to return even after updates.
For the price of this cat flap, I expected a reliable product that would make life easier, not something that causes constant frustration and requires repeated contact with technical support.
Unfortunately, I cannot recommend the OnlyCat cat flap in its current state. We simply need a cat flap that reliably recognises our cats and lets them in and out, rather than one that seems to have a mind of its own. For the money we’ve spent, it just isn’t worth the hassle.

The cat flap has been running reliably for over a year and even detects leaves and feathers the cats try to bring in. At the start it had to be replaced twice – probably just bad units. But since all of that was handled well, I'm very happy as things stand and still give it 5 stars.

Die Katzenklappe läuft stabil seit über einem Jahr erkennt auch Blätter und Federn die die Katzen reinbringen wollen. Anfangs musste sie zweimal getauscht werden. Waren wohl Montagsgeräte.Da dies aber alles gut funktioniert hat bin ich ich zum jetzigen Stand sehr zufrieden und gebe trotzdem 5 Sterne

Make sure to clean the camera from time to time to reduce false positives (happens rarely, mostly due to dirt on camera lenses or if the cat tries to enter too fast and doesn’t show its snout.
