💬 In Wall AC/DC Pcb (with Relay) for MySensors (SMD)



  • reat looking project! Are the packages and silk screen for the two fuses custom? I'm terrible at creating eagle, parts, was wondering where you got them from. Thanks!


  • Hardware Contributor

    @AdamAnt - I have created the myself i think.
    Silkscreenm do you mean the name? "Fuse". If you change the name on the component it will change.

    Hi, it's a great project !! how can i make this PCB ? Do you know a site url to make this ?


  • Hardware Contributor

    @tonnerre33 - im a couple of days from recieving the board (second try). I will asemble it with instructions and release the files.


  • Hardware Contributor

    I received my boards today. Away for a week but will assemble, test and release files asap.

  • Looks really promising!!
    This is exactly what I lookin for.
    The safety concerns in this project is right on target!

    I have a small update so you know this isn't dead. Still much irl to do and cant find enough time at the moment but... the 5v side with the Mysensors time aware sketch works great.

    Some small changes was made to the schematics but nothing major. Next upp is 240v av side that needshe to be tested and then the relay.



  • @sundberg84 yes, irl can be tough 😊
    I'll be watching your project, keep up!


  • Hardware Contributor

    Everything is moving along slowly... 🙂

    Today i tested the relay function, the AC - DC (HLK) and if everything fitted inside the 3d box.

    Found some issues with the relay... it opens ok, but I cant close it again so the relay remains open... I need to figure out (or ask) if there is something wrong with my schematics or if the relay I used was bad.

    Also I have to add some mm on the 3dbox in the holes for the relay and HLK.

    I have uploaded some images and the eaglesfiles - but I would not recommend to create any pcbs yet - im not satisfied with the result and things will change on the layout and other.


  • Hardware Contributor

    Updated the 3dbox with some variants...
    From left...
    Box with access to MysX Connector
    Box wthout any access to inside (except AC screw terminal)
    Box with hole for a g3mc-202 relay and no other access.

    I hope to add a stl 3d viewer soon.. starting to get a grip on three.js :).



  • Hello. Please write size of the device in the box.


  • Hardware Contributor

    @vladimir The PCB is 50x36 cm.



  • @sundberg84 Please tell me, how you can connect a maximum output devices into an outlet controlled by the relay? As I understand it, it will not sustain even the kettle?
    I apologize in advance for the stupid question, I'm not good at electronics.



  • @vladimir , you are correct, in that you can only connect a load that is less than the rating of the relay's, or you can cause damage. Realistically what you would do is use this unit for lighting where the load required can be calculated and won't really change, or if you were using it for a switch, you would need to have some kind of labelling noting that it was only for a maxmium xxxW output.


  • Hardware Contributor

    @vladimir - yep, and for protection there is a fuse.
    Maximum for the G3MC-202PL is 2 A at 100 to 240 VAC



  • Cool design! Could you post the dimensions including box and relay?
    I understand one can update firmware through the MYSX connector?


  • Hardware Contributor

    @ragflyer - Thank you!

    I suggest using the ISCP to update firmware. There isnt any DTR (to reset) on the MysX (this design - its coming next revision).
    The box is 56mm wide and 43mm deep and the height is 24.6mm
    Uncluding the SSR relay sticking out its 29mm height.



  • Hi sundberg84,
    what's the status of this great project? can I produce the PCB? I want use this for sopstitute my current X10 plant based on around 20 micro module.
    only one question, I need to control light also by a traditional switch (momentary button) where a can connect the normal switch, A1 or A2 to GND is OK? in my case can be lot of distance from the node to switch, in some case more them 4 meters and the wire for control switch run in a same pipe to grid linee, can this plant create interference? what do you think to insert one optical cupolaed?
    Thanks..
    MArco

    @fra290 - Hi!
    Status is that I have just received the updated new PCB and are planning to test them... but havent had the time.
    I have updated openhardware.io with 7.1 which is the latest and the one im testing.

    You can download the gerber or eagles files and manufacture.
    I have also made a request for the pcbhouses to add 7.1 so you can buy them from openhardware.io

    Its small revisions and I dont think there should be any major issues with 7.1
