DoorOpen 
Transform any electric lock into an electronic lock - for doors, gates, garages, and also for Bed and Breakfast, AirBnB, Booking, HomeAway Vrbo; also MQTT 
(versions: DO) available [get it now - below]
 
With DoorOpen it takes a few minutes to transform any existing electric lock into an electronic lock that can be controlled with a smartphone or a PC via WiFi, which can be used, for example, to provide remote access to apartments rented with AirBnB, Booking, HomeAway, etc. 
Basically, to use it, it is not necessary to have Internet or anything else, as it creates its own WiFi hotspot and its own website (wfeasy.com), thus offering absolute security (to open the door you need to know the password of the internal WiFi, if you do not knows, nothing to do!). 
With a WiFi / Internet there are some extra functions. 
 
DoorOpen, among other things, is a safe and very economical way of not having to provide any tenants with the keys, for example. of a door, a gate, etc. (and therefore not having to change them, make copies, etc. which for some locks already costs more than a DoorOpen unit... so it will "pay for itself" immediately!!). 
DoorOpen supports 1 lock; we have also DoorSwitch2 for 2 locks / garages / gates and with more features.

("classic" version, dimensions about 84x30x20mm; fixing holes 3.5mm, hole distance 75mm) 
 
DoorOpen can also be used to make your home more modern and comfortable, allowing you to remotely control any electric lock from a distance, without wires. Just have your smartphone behind and you can even forget keys or remote controls ... in fact it costs even less than a coded teleCommand, and is safer and more comfortable! 
If you want, you can also integrate it into an automation / home automation with HTTP or with MQTT to use it with various HUBs and / or Home Assistants, for example ControlHUB. 
In addition to doors, it is also suitable for many recently installed garages and gates which are operated by pressing a single button (which closes if the gate is open, opens if it is closed); in this case in practice it simulates pressing the button, and can replace or complement the remote control. It can also be used to activate and deactivate any electrical appliance (from the light bulb to the refrigerator). 
 
To summarize with a diagram, here's everything it does (but it's not mandatory to use everything!):

How it works? 
You connect to the DoorOpen's own WiFi hotspot (which is called wfeasy.com - you can obviously change the connection password via a protected service menu, the standard one is visualvision; your phone/PC can memorize the WiFi/password for fast use), you request the (virtual) site wfeasy.com with any Internet browser (eg Safari Chrome Firefox etc.) the main page is shown as below: you click the padlock and the door opens. 
That's all!! 
You need the Service password ONLY to set things.

If desired, it can also be connected to the home / company / laboratory WiFi etc. and access it through that WiFi, and / or you can connect to an MQTT Broker for automations that use MQTT; or you can use it for automation via the more immediate HTTP (Quick manual...). 
 
It works both with interphones and opening systems (garages, gates) (the control unit terminals dedicated to the opening button will be used; or it can be connected directly in parallel to the door opening button) or with direct connection to a common electric lock. 
Very often it can be powered from the same interphone / control unit / lock power supply; the multi-voltage version works with normal 12V AC locks, but also with those 12V DC. or 6V AC o C.C. or any other direct or alternating voltage from 5V to 12V; in short, 99.999% of existing systems.  
The opening action is the activation of a relay of which both the normally open and the normally closed contact are available, maximum 220V AC.10A. 
The duration of the opening impulse is adjustable; or it can work in ON/OFF mode. 
 
Connection for direct use with single lock (we directly disassembled a lock to take the photo):

Connection with intercom system; or in parallel with the door opener button or the existing gate opener garage opener: 
serratura elettronica applicabile a citofono esistente 
in practice, the two wires of the white cable must be connected to the two wires that go to the existing button (for example, the terminals of the existing button can be used to insert the two wires, or connect to the control unit). 
 
Most of the power supplies for locks and intercoms are in alternating current so the polarity of the wires does not count. 
If, on the other hand, you have a DC power supply, well in many cases DoorOpen will work even if you connect it to the AC terminals, in any order (however, the + for the lock must be respected, if it requires it!) but it is better to use the DC connector 5.5mm with control unit + POSITIVE and external -NEGATIVE / GND - it is absolutely forbidden to connect to this connector to A.C. 
A 5.5mm USB cable can also be used to power DoorOpen: 
 
 
We repeat that the device does not require an Internet connection and / or be connected to some cloud (eg. Alexa, Google or other proprietary things) so: 
- it always works: even during Internet or cloud outages; 
- it is private and secure (even more than an encrypted remote control): no hacker or any government agent (ours or abroad) will be able to open your door from the Internet if DoorOpen is not connected to it, and not even any geek kid. Likewise, no one will be able to know when someone enters or leaves the house; 
 
Obviously it's up to you to choose a difficult password for the WiFi, if you put "mickey" as the password, or the phone number that is on the phone directory next to the address ... then you can't complain !! 
For the more skilled on the technical side, it can be used in an industrial automation or home automation system since to control it is enough to request simple URLs in http:// format. Or it works with MQTT and then interfaces with many existing automation and Home Assistant systems, including the ControlHUB controller. 
 
NEW: In addition to DoorOpen we now also have the new DoorSwitch2 which allows you to drive 2 doors (or garage, gate, locks, etc.) and also two switches (e.g. to operate garage and light), and receive information from up to two limit switches, or photocells or infrared detectors or so... 
OTHER NEWS: We also have a version that clips onto a DIN rail: 
 
(version for DIN rail / DIN rail with clip mounting - it can be hooked from above and then the clips below are helped; dimensions about 72x40x23mm)

Quick manual for DoorOpen 
First you will need to physically install the device; do it yourself if you are practical, otherwise get help from an electrician. 
 
 
With an existing installation for the door / gate / gate / garage etc. one of the best places to place DoorOpen is where the system control unit is located, because both the power supply (e.g. 12V) and the opening contacts can be found there; if you want, you can also place it elsewhere, for example where you can easily put yourself in parallel with the opening button. 
The power supply can be given either through the left terminals as in the figures above (both direct and alternating, any voltage from 5V to 12V), or if in direct current using the 5.5mm DC connector (central positive external ground). 
NOTE that the 5Volt version must instead be powered only and always at 5 Volts in Direct Current (eg with the USB cable provided). 
 
A. CONNECT AND OPEN THE DOOR 
1) connect to WiFi wfeasy.com - the initial password is visualvision 
 
2) connect with the browser (Safari, Chrome, Firefox etc.) always to the wfeasy.com site, if you want you can use (and/or provide) the QR: 
 
 
3) the page below is immediately shown, to open click the padlock 
apertura porta con wifi 
("Service" is needed only for the setups) 
 
B. CHANGE THE PASSWORD AND DEFINE THE VARIOUS OPTIONS (EX. CONNECTION TO HOME WiFi) 
1) connect etc. as in point A 
 
2) in the "Service" box enter the password (the standard one is pippo - change it!); the configuration page appears; at the top you can choose the language and reset: 
 
 
3) immediately below, you can connect eg. at home (or office or whatever) WiFi; to do this, select the WiFi, enter the password, "Save" (sometimes it disconnects here; just reconnect) 
 
 
4) still below, the operating parameters can be defined: 
imposta serratura elettronica 
 
For parameters, "Unit name" is the name given to the port (in case there are several); WiFi / User Password and Service Password are the passwords (in the image the standard ones); "Opening pulse" is the duration of the impulse it takes for your lock to open, usually 1 or 2. 
If you are connected to a WiFi, at the bottom DoorOpen displays the name of the WiFi and the IP with which the lock can be accessed. 
 
C. USE IT WITH MQTT 
The easiest way to use DoorOpen, even with automation, would be to use web commands (e.g. wfeasy.com/?d=3 or [IP address]/?d=3 open/close, 33 off/close - when required) but MQTT it is very popular for automation and in particular home automation and Home Assistants, so we have put this function as well, click here for the page with the DoorOpen MQTT manual... 
 
D. ACCESS THE LOCK/SWITCH WITH YOUR HOME / OFFICE / ETC. WiFi. 
1) connect etc. as in point B 
2) in the settings, set the WiFi name and password always as in point B 
3) at the bottom of the window, it will indicate the IP it assumes, eg. 192.168.1.14 
4) at this point connected to the home / office / laboratory / whatever WiFi 
5) click the link or type the IP in the browser bar, for example 192.168.1.14 or http://192.168.1.14
