ControlHUB is a very ingenious Hub / Controller that can be used for general and home automation, with a truly great versatility considering the variety of devices that such a small, economical and low-consumption device can read and control.
It can receive "variables" or data from sensors connected directly via wire (RS232 or ModBus industrial standard), or remotely (via WiFi or 433Mhz, from MQTT or HTTP devices or even from websites / Internet); then on the basis of conditions and/or formulas that you specify visually, it can perform actions (command relays, command wired or remote devices - such as the aforementioned, send MQTT commands or send data and commands to websites or devices that act as a website).
Some versions can also mount a SIM card and so you can phone or send a SMS in order to trigger a Action.
Like all our devices it is totally open, not being blocked on external clouds or proprietary systems, and can be configured via internal WiFi with a PC, Mac, Linux or smartphone through a comfortable and truly ingenious visual Web interface, usable without the need to be technicians or experts, without codes or programming.
It is not possible to summarize all the things it can do, there are too many. Schematic example of reading / condition / action, even complex: if (variable1>25) and (variable2*variable3<2) and (time>1600) do action1[sending variable4]
You can do simple things (such as operating a refrigeration system if a certain temperature is exceeded; turning on pumps or solenoid valves to irrigate if the ground is dry; turning off an electric fountain if the wind exceeds a certain speed or after a certain time; driving a variable speed fan more or less fast depending on the temperature ... etc) as well as much more complicated things ...
The D versions have a large and very bright display (like DisplayRX), the Cs have an LCD display, the Ns/Ms have no display.
DY, CY, NY, MY versions include internal relays. 
(versions: INT4, INT8, EXT4) available
It is a large and bright display with 4 or 8 letters/digits, with 7 segments, designed to show multiple data received from multiple sources, HTTP, MQTT and/or 433Mhz, creating its own WiFi even without the Internet, if necessary.
The management of data/variables is very similar to that of the ControlHUB hub / Controller (which in addition to receiving data/variables from external sensors and showing them, can perform actions in relation to data and conditions, see website...).
It can receive one or more TXdata / TXtemp / TXsoil, and one or more third-party devices operating in MQTT or HTTP, and shows the data received in rotation on the display in the order and times chosen by you (possibly also showing a label / label).
For the data received from TXdata that are potentially of infinite variety, you can choose the type of data shown and how to obtain it from what is received (visually extracting both the classic Hex data from ModBus registers, and one or more variables from a JSON text sent as a message in an MQTT Topic).
The 4-digit version can marry a 504 Ticino or 71304 Vimar wall box; the 8 letter / digit version is obviously more readable when there is a lot of data to show (but you can already do a lot with the cheaper 4).
DisplayRX can be configured and read with a smartphone or PC / Mac, with just a few clicks.  |

(from 16€) available
With DoorOpen it takes a few minutes to transform any electric lock into an electronic lock that can be controlled with a smartphone or a PC via WiFi even without having the Internet/WiFi. DoorOpen2 supports 2 locks.
It can be used to give access to rented apartments, for example with AirBnB, Booking, HomeAway etc .; to provide remote access by leaving the keys inside the apartment or without having to provide keys (and therefore avoiding changing keys); or simply to remotely control a lock or gate or garage without wires, or in addition or replacing a remote control, even a coded one.
It can also be connected to your home / office / etc WiFi. but basically you don't need a WiFi or Internet, since it creates its own WiFi and its own website. You connect, main page, click on the lock icon, and the door opens.
No apps and / or connections to external clouds are required: so it can be totally secure and independent.
It works both with intercoms and with garages and gates with push-button control, or also even connecting it directly with a common electric lock. It can be powered from the same power supply that powers the intercom / lock; its multi-voltage version works with normal 12V AC locks. and also with those 12V DC. or 6V AC o C.C. or 9V or any other DC or AC voltage from 5V to 12V. The opening impulse is adjustable.
DoorOpen can also be used remotely with the most popular automation systems via MQTT or with simple HTTP - so if you have a Vocal Assistant and you know how to configure it, you can open garage, doors and gates with your voice. 
(from 29€) available
DoorSwitch is the evolution of DoorOpen (see above): a PC, a Mac, a Smartphone or a Linux system is enough to control remotely up to 2 switches or up to 2 locks / doors / garages / gates. Up to 10A, 220/240V.
DoorSwitch is not limited to this doubling but adds the possibility of reading the status of 2 switches: two "limit switches" or of two simple switches or two photocells (limit switches can be used directly by DoorSwitch to show if a garage or gate is closed; moreover the status of the contact is transmitted in MQTT - if activated; example of application with ControlHUB or other automaction: if the garage is still open at 10 pm, a closing impulse can be given).
It can also be connected to your home / office / etc WiFi. but basically you don't need to have a WiFi or Internet, since it creates its own WiFi and its own website. It works with a simple web-like interface that doesn't require you to install boring apps because the browser is enough (Safari or Chrome or Firefox or whatever): it displays padlocks or on-off switches to click.
To enter you have to enter the password of his WiFi (which you decide) and it is therefore absolutely safe.
If you want, the doors and / or switches can also be operated remotely with the most popular automation systems via MQTT or with simple HTTP.
If you only need to open one door / gate / etc, see DoorOpen above.  |

(versions: I, E; from 47€) available
It is a luminous panel with two very large, high-brightness digits, which serves to show the number of those who are entitled to be served in a queue and therefore to maintain order. You can configure and forward the number with a remote control, or through its internal WiFi (therefore with smartphone / PC / etc.); and even with HTTP or MQTT automaction.
Supports external displays: the number can also be seen / repeated on the screen of one or more phones / tablets / computers / TVs that have WiFi, simply by connecting the device to QueueNumber WiFi; in other words, any device with WiFi can act as an additional external "monitor". Wireless and without the need for the Internet.
In addition, if you connect it to the Internet through your WiFi router, automatically the customers or patients to be served will be able to see what the current number is even on the Web (via a QR code that can be hung nearby) and therefore if the queue is very long they can be absent for a long time and, wherever they will be, continue to know where the queue is via the Web - useful for clinics / healthcare and all those places where you have to wait hours.
It is also usable in MQTT so if you have a good Assistant and you know how to use it, you can send forward the queue number even by voice!
One or more QueueNumber can be put in tandem through a MultiQueue. 
(versions: I, E from €95) available
A MultiQueue allows you to put together several QueueNumber that are different 2-digit displays that are used to show the number of those who have the right to be served in a queue and keep the order, when the number is unique but there are for example several dispensers of a given service, and each comes forward and calls his number.
The set required for tandem operation is made up of a MultiQueue unit that automatically communicates with the various QueueNumber units connected to it.
You can configure and increase the number via remote controls and the internal WiFi (with a smartphone or a PC / Mac), it is not necessary to have a WiFi or the Internet, since the MultiQueue works in practice as a WiFi router for all elements.
For example, if there are 3 displays and 3 counters, each counter will be able to increase its number (and this will happen automatically in coget it now - belowtion with the others).
Supports external displays: the number can also be seen / repeated on the screen of one or more phones / tablets / computers / TVs that have WiFi, simply by connecting to the MultiQueue WiFi
In addition, if you connect MultiQueue to the Internet via your WiFi, the customers or patients to be served will be able to see what the current number is also on the Web (via a QR code that you can possibly hang) and therefore if the queue is very long they can be absent and keep knowing where the queue is - very useful for clinics / healthcare or wherever you want to make long queues more bearable.
It can also be used in MQTT for automation.  |

pane especially for developers:
(versions: RAW) available [for developers]
It is a large 4-digit display, without box, usable for electronic projects. It is a large 7-segment 4-digit high brightness LED screen. It can display numbers and, quite well, even letters (with the obvious limitations of 7 segments; but without any effort thanks to a ready-made software library).
In RAW version it needs 3.3V power supply (max 3.8V) and is controlled with 2 basic signals SI SCK; or if you have more GPIOs available you can also use RCK PWM (4 GPIOs at all) and have better scrolling, and variable brightness.
Arduino / ESP library to use it available on GitHub (link with examples; easily adaptable also for Raspberry); note that the visualization is static (not multiplexed: it does not require interrupts, so it looks better and does not slow down your program).
Several units can be cascaded (practically unlimited).
(versions: RAW, C4, C8, IND4) available
It is a 7-segment LED display with 4 or 8 large digits and high brightness.
It can display both digits and sentences, even scrolling (with the limits of the 7 segments but fairly legible).
It is set via internal WiFi and can be controlled via: WiFi / HTTP (manual for HTTP WiFi commands); WiFi / MQTT (so it can be used for automation: a hub and / or Home Assistant can use it as a display, showing numbers or even scrolling sentences; MQTT WiFi manual...) RS232 serial interface (2 wires are enough: TX, GND; serial commands manual); or it can be controlled / connected via the ModBus RS485 interface (A, B; ModBus commands manual for Display8888).
It is available in 4 or 8 digits, without box (RAW), or in commercial or industrial box.
It can be configured with a smartphone or a PC or a Mac, with just a few clicks, without the need to install an App.
Requires DC 5V power supply.
(versions: 80cm, 3mt) available
It is a probe to be used to measure the soil moisture, for gardens, fields, pots, or the presence / level of water for example in tanks or other containers, wells, drinking troughs. It is capacitive, very resistant to corrosion and the humidity measurement does not depend on the salinity of the soil. It needs a constant power supply voltage between 3 and 12 Volt (absorption less than 10mA).
It has an analog output (2KOhm output impedance) to which you will typically apply a load of 1MOhm. With power supply at 3.3V and load about 10MOhm the "dry" output (humidity 0%) is about 2.5V, when immersed in a jug of water (humidity about 100%) the output is about 1.5V. |
