Hey everyone, I’ve noticed a lot of posts about using the Sonoff SV on folks gate motors and a I’ve seen HA covers where the gate status is shown (open/closed).

I’ve seen some people use reed switches however, fortunately my Centurion D5 motor has a status pin which turns on an LED of the gate is open.

Has anyone been able to successfully connect their Status pin to their SV GPIO port?

I’ve tested with a multimeter that I’m at 0V when closed and 5V when open. I almost thought I damaged my board because initially I just connect the pin to the GPIO port forgetting the max input on ESP devices is 3.3V , however the Sonoff SV can in fact handle 5V. So I’m not sure as to why it’s not reading the status , I’ve used a simple binary sensor in my ESPConfig.

Appreciate the assistant
 
My sonoff sv use the led for status pin. On tasmota. No idea the volt on my led and I have a different motor.

Did you just directly connect the status led from the motor to the SV device?

Pretty much. The only thing I did check, was to ensure I keep negative/ground the same, because the led positive is only wire that connect to the gpio pin on the SV.
 
I checked that too , and made sure I don’t have a floating value with a pull down , it’s keeping me up at night that I can’t figure this out :/
 
I do not think it is possible using the Sonoff SV, with for example a D1 Mini (which can handle 5V analog input) you can use the A0 pin to read the voltage and then use this to know the status. When using a Digital Input/Output I would recommend a reed switch or switches for this. I have used the Analog pin on my old alarm to detect the armed/disarmed status before I upgraded my system to Paradox.
If it can be done with an SV I would also be interested.
 
@InusB so I met someone who got it to work , and per their instructions I'm still struggling, initially the plan was to use a reed switch, just thought I could find a less messy solution, if I don't come right, the reed will have to do, if I do come right, will let you know !
 
I use a reed switch.

But what is the concern here the external voltage? Use an opto-isolator(opto-coupler/photocoupler)

binary_sensor:
- platform: gpio
pin:
number: GPIO4
mode: INPUT
inverted: False
name: "Gate Status"
id: gate_status
device_class: garage_door
filters:
- delayed_off: 500ms # Adjust the value if needed, this adds a delay to the OFF state to account for gate motion
switch:
- platform: gpio
pin: GPIO12
id: relay
- platform: template
icon: "mdi:arrow-up-down-bold-outline"
name: "Gate Control"
turn_on_action:
- switch.turn_on: relay
- delay: 1500ms
- switch.turn_off: relay

sensor:
- platform: wifi_signal
name: "Garage Door WIFI Strength"
update_interval: 60s
- platform: duty_cycle
pin: GPIO4
name: Gate Percentage
