Hi All,

Looking for some help here

I have purchased a sonoff switch and would like to connect it to my garage door opener,

Have read a few links on the internet where it shows that Sonoff be directly be connected to the garage door opener module as there is still no "pulse function".

Also my garage door module has this following items ,PB,PE,GND,LMP,+24V.

iam assuming that i will need to connect the "modified sonoff" to the PB and GND to work as a on/off switch.

If anyone has any ideas or diagrams would be very good,i have basic electronics skills

I drew a simple diagram for a software modification 

Try using these momentary switches http://eachen.cc/product-category/diy-samrt-home/

the only problem is that the status is reported as on/off or the command you give to Alexa is turn on/turn off instead of open and close which makes it cumbersome to remember. however you can create a routine in the Alexa app called "open garage door" and it works more intuitively.

Bom Dia, voce pode usar o Geekcreit® USB 5V Or DC 7V-13V DIY 1 Channel Jog Inching Self-locking WIFI Wireless Smart Home Switch Sokcet APP Remote Control, ele pode ser usado como pulso, só que não informa o estatos do Sonoff, só durante o acionamento, mas funciona, e ainda coloquei um botão auxiliar.

Hi Ash, you can use one of this. You connect the relay connectors as it if were or in paralel with the activation button. You need to set this PCB to pulse (inching mode).

Hi

Thanks for the update but i already got a 1-channel sonoff device.

how do i interface to a 1 channel sonoff?

 Hello,

you have various possibilities. You can attach the Sonoff directly to the external input of your garage opener. Unfortunately, all sonoff have a potential contact (230 v in and 230 v out).
I solved it with the sonoff 4ch pro. This has potential-free contact that you can connect to the entrance of the garage opener. Or simpler: braze two wires on the micorswitch of your remote control of your garage opener and now you can connect it to the 4ch pro. then you can operate on the contacts also several remote controls (picture).
Then you can set a pulse from 250 ms (0,25 sec) up to 4 sec.
