There is an Italian company that few people know, but that everyone has used a product of once in their life. It is called Finder and was founded in 1954 by Piero Giordanino, the inventor who in 1949 patented the first the first modern locking relay.
Finder is now an international company, and its products are used in both residential and industrial environments. Among the more than 14,000 products in the catalog, Finder also has a system that allows you to make homes, new buildings or old homes smart by adding simple modules.
The system is called Yesly, and it is totally designed and developed in Italy: the logic is similar to many other modules spread around the world and is based on different technologies, from Wi-fi to Zigbee, so we are faced with small devices from plugs into wall sockets, existing systems can be adapted without much effort. The footprint is really minimal, as shown in this picture we took by comparing them to a regular plastic cup.
However, the Yesly system is not comparable to that sold by many other manufacturers, especially Oriental: instead of Wi-fi, which has a high base consumption and presents various problems, such as the need to update the password for all forms, if you have to change the hotspot password, Yesly uses Bluetooth Low Energy. This solution lowers the consumption of the individual module and utilizes a technology that has been tried and tested, on which a communication framework has been built that makes the transit of data secure.
Among the other benefits of the solution, it is also Made in Italy, and it has been created by the company that wrote the history of the relays: a module for controlling the lights, or an electrical outlet, is nothing more than a relay. smartly controlled by a smartphone, a switch or voice commands.
Since these are products that need to be installed inside a domestic electrical system, safety and reliability is a significant prerogative: behind Yesly there is all of Finder’s know-how.
New or retrofitted system, it changes a bit: installing it is very simple
As always, when it comes to systems that require intervention in the electrical network, the suggestion is to leave it to someone who has exactly an idea of what to do and where to put their hands. However, these modules are also sold on Amazon, and anyone who knows the composition of a system, knows how to distinguish the phase from the neutral, has an idea of how switches, converters, inverters and buttons are connected, can easily try the DIY way , because everything is really simple.
The Yesly solution contains two components, a hardware part and a software part for programming and configuration.
The hardware part is made up of several modules, each of which has a very specific role, especially in relation to the type of system you want to make. Yesly is perfect for those who need to renovate their home and remodel the electrical system, and in addition, the solution can benefit from the tax relief, or for those who want to make an existing system smart. In one case it will be preferable to focus on the more practical buttons, in the other case the modules will instead be inserted next to the switches and inverters already present.
Inside each type of module there is an instruction sheet in Italian, which explains in detail all the different configuration modes and also shows the different connection modes, and for our “retrofit” test, or how to smartly make a switch that does not, and we have perhaps chosen as the most flexible member of the whole group, the multifunction relay 13.21 B. Same dimensions as the other modules, it fits easily in a wall box, 16A clean switch and 12 different operating modes that can be selected via the configuration app.
We have chosen this component as an example to show in a “practical” way, also in video, how to make a traditional switch that turns on a light intelligently and remotely, therefore the typical switch that interrupts the phase present in all the houses built a couple of decades ago ..
Today, a classic “non-smart” system can be represented with the diagram inserted just below: there is neutral and phase, of course in the lighting system, there is a switch that interrupts the phase, and there is the load, the bulb. This base can then be “extended” by adding more contacts: If you want to access the bulb from two different points, you need two contacts, if you want to turn on the light from three different points, you need two contacts and an inverter . A classic.
Here’s how our system changes if we add the Yesly module: the modification of the system is minimal and does not require the passage of additional cables, everything can be done inside the box itself, where the contacts are located: you just need to bring the power supply to the module and control the phase.
After connecting the module and checking that the connections are correct, only one last step is required: by using the Finder Toolbox app, which is necessary to configure the system, the module is assigned the function that suits the type of connection, which in this case is “Rlà, pulse relay (contact control)”.
The app that communicates with the module via Bluetooth will write the configuration in the module memory. The module is an embedded system that has its own processor, its own memory and has its own life even without the need for an app: the app is only used to create and load the configuration.
As we wrote before, if you have buttons instead of switches, or if you want a timed system, then the classic button that turns on a light that turns off automatically after a certain amount of time, simply adjust the wires and change the function of the module ., by selecting, for example, “Time-controlled stair lighting”.
The pleasure of a flexible and modular platform
At this point, we find ourselves with a bright spot that has been “transformed” from a traditional system to a smart system. The switch continues to work, the system works even when there is no internet connection, and using a smartphone we can test the connections to check that everything is correct: the light turns on and off itself from a smartphone as well as from a switch.
Like any self-respecting smart system, this is just a small piece of the puzzle, for Yesly is as flexible as any other system on the market and in some respects it is even more practical and immediate. What if we were to add a switch to our light in a place where we can not get other wires through?
There is a module called 1Y.P2, which allows you to connect two buttons, and each of these buttons can be used either to start a specific scenario or to turn on and off our smart switch. Just tie it.
If desired, there is also a “totally wireless” solution: The small Yesly Beyon Wireless Button is a kind of programmable remote control that can be connected to different scenarios or different modules to give a specific command.
The 13.21-B multifunction relay, which has a clean switch, can also be used for a door opener or for switching on a device, and The Yesly Beyon Wireless Button can be stored on a coffee table or in your pocket to kickstart the action.
Yesly was smart enough to make it magnetic and without the need for a battery: it hangs on the fridge and any metal support and has four buttons, each connected by a command.
Yesly is a real control app
While the Finder Toolbox app is intended for installers and those who need to configure the system, to link the various modules together and add new parts to the system, there is an app dedicated to those who then need to use the smart system.
It’s simply called Yesly and has nothing to envy the most noble home automation apps: you can create one or more houses where you can create spaces, each with a color and an icon. The various units are attached to a room, which can then be organized to handle complex scenarios.
A house or part of the house units, it can also be shared with other family members enables total or partial control. You can also enable access to an installer who will help remotely manage or configure a system in the event that a user is not so convenient or finds himself in trouble with the scenarios.
The app is simple but really well thought out, and even the tiling of the home helps to move around the different spaces to control every single accessory present.
The wireless gateway causes Yesly to talk to Google and Alexa
We wrote that the entire Yesly system works using the Bluetooth protocol: it is efficient, has a reduced latency, but still has a limited range of action, a maximum of 15 meters. There is also a solution to this: Finder has created a wireless bridge that allows you to insert every single component of the system into a wider platform while preserving all the functionality.
Through Yesly Gateway, the system control is transferred from Bluetooth, which will continue to be the communication solution that the modules use to talk to each other and with the gateway to 802.11b Wi-Fi: The system then enters the network. The gateway allows you to connect the system previously created with Alexa or Google Home, or to use it in IFTTT automation scripts.
Also in this case, the operation is really simple: when it is turned on, the gateway is instantly recognized by the software (just enter the data on your home network), and by specifying which devices can control the individual gateway, the configuration of the device is written and uploaded to Yesly cloud for remote access.
To use Google Home, just select “new device”, select “Yesly”, and our contact will appear in the space to which we associate it in Google Home, and will also be recalled with the voice command “Hey Google” via Assistant.
Taking advantage of the gateway therefore achieves various benefits: the operating range is extended, also because the range of Wi-fi is wider than Bluetooth, the system also works remotely thanks to the Cloud Finder, the shutters or the irrigation system they can thus be turned on even when we are not at home and above all, Yesly controls can be integrated with external solutions. For example, Beyonnen can be used to access a connected coffee machine and wireless bulbs that are not Bluetooth but connected to the Google Home system or Amazon Alexa can be controlled via the Yesly modules.
When a system costs
Yesly products are sold through installers, and it is advisable to be followed by a Yesly installer (here is the list) to design a system that suits your and your home’s needs. It is not possible to define an exact price for a system, but the modules are also for sale on Amazon at prices ranging from 40 to 70 euros depending on the type of module required, and calculate the possibility of deducting the system and the number of light points you can more or less understand how many modules you need. The price of a complete system is certainly lower than for a classic home automation system, and compared to other similar solutions, always based on modules, offers the advantage of reliability and security that a brand like Finder with its history can guarantee.
