Cover Function for Garage door or in my case Gate, I can not get it to function like it should(update just made it work)

Configuration
1

Update, just made this work, but want to leave it here for others to be usefull.

Hi everybody, i am trying to use a modified sonoff basic to open and close the garage door or main gate and show the open state with a reed switch.
I know this has been mentioned many times before, the past few days i read almost everything about it i think. But i still can’t get it to work properly.

Here is what i have.
I modified a sonoff basic so that the relay acts independent from the incoming power.
So is it switches, it only makes a contact.
I programmed it wit the latest tasmota where i filled in the things needed for wifi and mqtt.
I also set a pulstime of 10 so that whenever i activate the switch it is only pulsing on for 1 second and then stays off again.
I set the mqtt topic to sonoffgate
I connected the reed switch to ground and GPIO14.

After starting the sonoff for the first time i set GPIO14 to 10switch2.
In the console I typed
switchmode1 0
switchmode2 2
switchtopic2 gatestate… This was my mistake, for some reason this does not work, this needs to be switchtopic2 2

When i test the buttons this shows up in the console
Switch

10:43:20 MQT: stat/sonoffgate/RESULT = {"POWER":"ON"}
10:43:20 MQT: stat/sonoffgate/POWER = ON
10:43:21 MQT: stat/sonoffgate/RESULT = {"POWER":"OFF"}
10:43:21 MQT: stat/sonoffgate/POWER = OFF

Reed switch

10:46:34 MQT: cmnd/gatestate/POWER2 = ON
10:46:38 MQT: cmnd/gatestate/POWER2 = OFF
So gatestate is now changed to 2, and gives me the same output

I made a binary_sensor in config.yaml like this.

binary_sensor:
  - platform: mqtt
    name: "gatestate"
    state_topic: "cmnd/gatestate/POWER2"
    payload_on: "ON"
    payload_off: "OFF"

This binary sensor is not needed for the cover to function correct but here i also changed gatestate to 2

This shows the state correct if i activate the reed switch so i assume this is working like it should.

I added this cover function in the config.yaml

cover:
  - platform: mqtt
    name: "test"
    state_topic: "cmnd/gatestate/POWER2"
    command_topic: "cmnd/sonoffgate/POWER"
    payload_open: "ON"
    payload_close: "ON"
    payload_stop: "ON"
    state_open: "ON"
    state_closed: "OFF"
    optimistic: false
    retain: false

Abobe I changed state_topic: “cmnd/gatestate/POWER2” changed to"cmnd/2/POWER2"

Added this in the customize.yaml

cover.test:
  friendly_name: front gate
  device_class: garage

At first i thought i would do this later, but it is an important step to make the mdi icon work and change. the line "device_class: garage" sets the icon.

Added this in the groups.yaml

  garage_doors:
      name: Main gate
      view: no
      control: hidden
      icon: mdi:garage
      entities:
        - cover.test

For some reason i don’t think that the icon line ads anything, but in all the examples i have seen its there.
I am tired of trying, maybe someone can tell why this should be here.

This is what my cover looks like in HA
cover
Now when i click the black arrow, the relay switches like it should.
The same when i hit the black square.
So that is all good.

When i activate the reed switch, the mdi icon changes to an open garage door.
That is also like it should.

The thing that i am struggling with is that the grayed out arrow stays grayed out no matter what i do.

A already spent my complete weekend trying to figure this out but i can’t find the solution.

I hope that this can help others.
I am glad i finally made it work.
