You will use this app every day!

I live in a 100 year old condo, with an intercom system from the ‘70s. Of course my system was not listed as being compatible, but it really is just an app controlled switch. The Nello support team provided a document showing what each of the wires does and with a little deduction, I was able to connect my system in a “simple switch” configuration. You need to be able to detect an incoming buzzer and close the circuit to trigger the door to open, the app provides the UI for controlling it. Home zone works, though sometimes it’s a little hit or miss (hence only 4 stars), time windows work well and I have a slider to unlock the door when I want. There isn’t anything else on the market like it.

Be careful with tech support...

The nello team has a tough job (i.e. corresponding with customers regarding their specific set up issues related to wiring, etc.) but this is the challenge of their smartphone device (and possibly why there isn’t a commercial product for wider distribution available). I’ve be trying for days to install the device, have corresponded with 4 people from the nello team but still haven’t received any clear instructions from them.

Before you purchase, be sure that you’re able to deal with the wiring challenges (if you have a multi tester and know how to use it you’re likely in a good position).

Ideally, Nello will recognise that they need to scale up their support. Once they do, they’ll have a unique competitive product! Until then, it’s just a little piece of plastic that’s not worth €110.

Being a gadget fan, I was amazed about the idea of connecting the intercom with my home. Nello got my attention as it was a Kickstarter. Due to some initial challenges with designing and testing a widely compatible equipment, it took the nello team some extra time to finalize and release their product to the backers. This might explain some of the initial negative comments received in the app review. Fortunately the delay was only noted during the pre-release phase (pretty common for Kickstarter and startups) as I have personally witnessed a very responsive and cooperative nello support team. There are multiple smart ideas embedded into their firmware and especially their hardware. Many of those challenges can only be noted, if you have a good understanding of the various differences in the protocols of all the supported intercom brands and models. Getting a plug and play nello device powered solely through the intercom (like a parasite ;) is the result of these smart ideas. For instance, true and secure wifi connection rather than BT, which would require an additional BT to Wifi bridge was achieved thanks to a big capacitor. SSID and password of your router are passed on to Nello via display flashes on your phone.

Once the tiny package arrived, the nello was very easy to install. I managed to conceal it within my intercom (model TCS25), as I also removed the plastic casing. It disappeared completely hidden inside the intercom. (Only disadvantage now: if I'd ever wanted to change my wifi password, I would need to open the intercom to gain access to the Reset button and the photosensor... I think I can live with that limitation :)

Thanks to the step-by-step guided app, the connection of the correct 2 wires was done within seconds. All tools 🔧🔩✂️needed to do the installation were part of the nello kit and included - I did not time-it, but I think I had everything installed and running within 10 to 15 minutes. (Note: I did also open - initially out of curiosity - the tiny nello casing which revealed the circuitboard - this is also how I managed to get the unit completely hidden inside my intercom. Of course this additional step is normally not required if your intercom is spacious or if you plan to install nello outside of the box).

Anyhow, as I mentioned already above, this App guides you step-by-step during the installation & setup process explaining how to configure the equipment - even for a non technically savvy person. In case you have some strange model or difficulties to identify the correct wires, the app gives you the option to make a picture and submit for assistance.

My family is using the nello app on a daily base and we are truly enjoying it: All it takes to enter our main building is sliding the finger over the display like unlocking your phone. No more searching for the keys (as long as your phone is charged and has internet access).

We are now able to provide access 🔑to the building to our visitors for the duration of their stay (email invite) or activate time based entry permits.

Every time somebody rings 🛎 the door, a push notification 📬is sent to the phone. You can then buzz the person in even without getting up from the sofa.
