Zigbee relay switch to control garage door that expects push button input?

Configuration Zigbee

Folks,

Ive got a Zigbee smart switch, a ZG-005-RF, with 4 relays.

3 of the 4 relays are used for my yard watering system.

Now I got an idea to use the 4th relay. I’d like to remote control my garage door, the big one for the car…

But that garage door system expects a push button input. Close a loop momentarily, the motor starts, and runs till either the next signal comes or the door reaches its end position in either closed or open state. To revers direction from moving, I need to close that loop twice.

Now, Ive got that zigbee relay switch.

Whats the best way to tell that switch to behave like a push button, like close the relay 4 for say half a second, initiated per push on a button in lovelace.

I do have some zigbee door switches, so I do know when the door is closed.

How would you move ahead to make it work?

What I would like to have, is something similar to the tasmota shutter system. Where I and HA would know where the door by its running time should roughly be. (so long nobody interacts manually with it.)

Maybe I should use some tasmota device and get all the input signals going though that too and by doing so also into HA…? Im open to any suggestions for that scenario too.

Thanks
Manny

The ZG-005 has inching capabilities, but I don’t know if you can set that up for only one of the switches.

yes i can confirm that

this gave me a few insights: https://www.youtube.com/watch?v=5bMVqeslqpk

but I dont know how to set it that way without the tuya environment.

I found out that I can switch between normal mode, interlock all 4 and inching all 4 by pressing the mode switch (thats sometimes labelled as reset switch). its confirmed by blue led blinking: 1 blink is inching 2 blinks is switch mode and 3 blinks is interlock 1,2,3,4 mode

by long pressing any channel button, it goes into 433MHz pairing mode… (blue led is on while waiting for pairing, about 10 seconds)

Just write a small script and call that when you want it to press the button. Turn it on, delay 5 seconds, turn it off.

As far as I know, any device that controls movement in two directions—whether it is a push rod type or a rolling door for lifting and lowering—operates based on the principle of motor forward and reverse rotation. This means you must have two relays to control it: one for clockwise rotation and the other for counterclockwise rotation.

Many garage doors just need a dry contact and they reverse themselves on every activation. I have a sonoff sv on mine and it’s all run in Tasmota. Pulses the button a couple of seconds when I want it to go or if it’s moving, stop.

Would I do it again, probably not exactly that way, but it works.
