  • Shelly UNI to manage a 12V motor + inversor + light detector : how to ?

    for internet i already have a shelly 1 working with intermittent internet and it keep the schedule, so thats a 1st way to work, but i will try to get internet connection to use also the sunrise/sunset.

    for the motor stops i plan to use that kind of schema as attached

    Fin de course : will be the detectors of position, ouverture is open when door is opened, fermeture : is opened when door is closed, otherwise for each they are closed, when one is close the other is open, and they each command a relay activating the motor and inversing the way of roration by inversing the polarities of the motor.

    Jour / Nuit : could be the Shelly Uni, but one question is that here we manage only the + wire, and the Shelly Uni will need + & - wires on both OUT1 and OUT2, here the - is permanently connected on the top of the schema. So i am wondering how the Shelly Uni can be implemented here ?

    for the mechanical part, the door will be a very light slider, about 500 grs, sliding vertically

    Edit : and yes there are solutions on the market but about 150 euros, so i try to build it, for fun mainly and also to save some euros... :)

  • Shelly UNI to manage a 12V motor + inversor + light detector : how to ?

    Oh thks for answer,

    In my understanding, the inversor is a circuit able to make the motor run in both ways, but its my undesrstanding at this stage. One way it turn clockwise, other way counterclock.... So OUT1 can command 1st way and OUT2 can command 2nd way. Would be perfect.

    Yes i can start with schedule, no prob, but i would like to add this feature which is daylight detection. And there will be no wifi were the Shelly Uni will be, so not possible to use sunrise/sunset, but i will test...

    For the detector, can i know more how i can build this LDR + fixed resistor ? I am not enough skilled on that side to define that but if i have the details about the components i think i can build it.

    Edit : Other question : after sending a command we must stop the motor at the end of the action.

    So i can add contactors (mechnical, magnets...) which will be closed for example when the right position is reached. Can we connect these contactors to the Shelly Uni to detect these two positions ? Or i should add something like a relay in the circuit.

  • Shelly UNI to manage a 12V motor + inversor + light detector : how to ?

    I want to manage a 12V motor to open or close a small door.

    Shelly Uno seems able to send power on two different output and maybe it could be used to send power on output 1 for opening, and on ouput 2 for closing ?

    I can have an inversor in front of the motor with these two entries.

    But i would either :

    - define a schedule based on hours of the day for open/close commands, the web server inside shelly can do that i guess ?

    - or connect a light sensor in order to close in the evening or open in the morning ? can we connect such sensor and which type or which model ? and how to manage ?

    And what will be the connection wiring in these situations ?

  • Shelly to replace a digital programmable clock for pool filtration pump

    Hi,

    i have a filtration pump for my pool managed by a digital programmable clock and i would like to replace the digital clock by a Shelly 1.

    There are currently 3 components :

    - the digital clock itself to be replaced by the shelly 1 (1st pic on left)

    - the relay activating the filtration pump and activated by the digital clock (1st pic on right)

    - a switch with 3 positions : left = permanent ON, center = OFF, right = clock managed ON

    I hope the shelly 1 can replace "only" the clock by connecting the current wires to the shelly connectors.

    What i am not sure is how to connect these wires.

    What i can see as wires on the digital clock :

    - left : 1 & 2 with M symbol between should phase and neutral

    - right : 3 orange wire goes to switch position permanent ON, 4 : 1 black wire goes to switch position clock managed ON, switch position OFF has a blue wire

    If this description is enough for you to help me finding how to wire the shelly 1 there i would be pleased to get ur advices.

    If you need more details i can provide.

    The goals is to :

    - be able to program the planning of ON/OFF for the pump directly from my Shelly App on my phone

    - still be able to use the switch for permanent ON, permanent OFF or scheduled ON/OFF as currently.

    So, at the end just replace the current digital clock.

    Thanks in advance.
