Hi all,

Currently I have this Sonoff MINIR4M. I need some clarification regarding compatibility with my autogate wall switch. Either this MINIR4M or Mini-D Dry Contact.

I am planning to use pulse mode, this relay will be in between my wall pushback switch (function - open/close gate) and the autogate. Mainly I am using this because it supports Apple Home. Those commonly used relay in the autogate box does not support Apple Home so its not an option for me. Does anyone know if this will work? My autogate is sliding gate and motor is CASA ASIA. I have done some research and some users have claimed it worked for them, but when I check with one electrician (to pull neutral wire), he keeps saying it will not work without justification. I will probably find another legit electrician for pulling the neutral wire.

both can work with correct power input and wiring.
but i read that u want to install behind pushback wall switch, if this the case, u need other power input to power up the module.. as the pushback button for autogate doesnt have power, its just dry contact (from what i know la)

usually the module is place inside the autogate circuit box. get the power from there (either 240v or 12v, usually people use 12v, more safer) and wired the dry contact direct to autogate board.

Hmmm, I did checked behind the pushback switch, there is two live wire. You mean both is from the autogate box and not from the distribution box? My understanding is one live from distribution box and one live from autogate box.

Also, my pushback switch is a bit special. It has a pushback button + on/off switch beside it (switch panel with two buttons). The on/off switch is to provide/cut main power to the autogate. Is it possible to tap power from it?

do you mean my relay should be installed inside the autogate box? If 12v, then seems like I should use the MINI-D dry contact.

This one works? I thought this is merely a switch. It should be the other type which has separate power for control and switch itself.

err based on the marketing ads and reviews from users, its purpose is more than just a switch. Comes with different modes for different usage.

Yes but I think the MINIR4M is the wrong one to use. My understanding of wifi switches is that there is two types. One that power itself like the one you mention MINIR4M. If you connect the L and N from the power, once you turned on the switch, the L will be channel to L out. You would not want to feed 230v to your DC autogate board.

Instead you should be using dry contact which feature an external power source which is separate from the circuit itself.

I myself also using something similar to what you mention. I had mine connected at my autogate wall switch instead in the autogate box because I fear of my wifi coverage not being good enough. Power using USB 5V (just use any regular phone charger).

Sooo I just bought the Mini-D which supports dry contact. Should I install it at the autogate board? Since I need to connect to the NO and COM. The thing is... my autogate has no backup battery so there is no 12v power to tap into?

Look for the transformer. There will be a couple of wires out of them. Then look at the board inlet power.

Why not take a picture and ask the installer to show you where the 12v are. Just hope it was not soldered dead like some of the board out there. Normal cheapo auto gate board all have screw in type which allow easy way to add extra wires.

Ooh okay thanks. I doubt the installer will help. When I ask about wifi relay, they introduce me their relay costing RM200 or Rm600 choices. I ask support apple home or matter? They say what is that. Based on their knowledge, they probably wont entertain third party devices and tinkering with their boards.

can u take picture of ur autogate board?
there should be low power output (12-24v) tap/point there.

Okay, I will try when I have free time.

I cant upload images coz lowyat system seems to having gateway error. Can you see the attachment? Seems like I should connect DC 12v + to '+PWR' and DC 12V - to 'COM'. But unsure which one is NO and COM. I checked some similar video on youtube and they say is the right side P.SW two connectors.

Is COM (of the mini d relay) supposed to connect to P.SW ('right connector') or to the COM (same connection with the DC 12V -)? Refer the last picture, is this correct?
12V+ -> +PWR
12V- -> COM (link with relay COM before connect)

NO -> P.SW (left connector)
COM -> COM of the board (link with relay 12V- before connect)

Pls ignore the cancelled lines, wrongly drawn.

Looks quite similar to ur board...

u can follow andrekua2 picture.
u do not need to loop the 'switch' contact to DC- supply.
just use C and NO to the P.SW connector.
