Liftmaster Logic 5.0/Konnected/Ratdgo

Third party integrations
1

I have a Liftmaster Logic 5.0 with Securty + 2.0 door opener that has a dry contact switch on the wall. I am having a hard time find out if any HA compatible products will work to simply operate the up, down and close functions of the dry contact switch. I dont care about knowing if it is open or closed etc, I just want the ability to control the door. For reference, I have attached a couple of pics.

Any feedback or tips would be greatly appreciated.

Thanks

Any esp relay board can be made to function in place of buttons

If dry contact switch is available, just get a D1 mini and a relay. https://www.amazon.com/HiLetgo-Relay-Shield-Module-WeMos/dp/B01NACU547

They make them integrated, but using a D1 mini makes it way easier to flash via USB.

Solder it up, put contacts to NO and Common. If no power near your contacts, extend them with wire. Often easier to extend the low voltage contacts than power to the esphome.

Make an esphome config. Trick is to make the on command just send a quick pulse. You might need a board with two relays, if you need a seperate button for up and down. Usually the dry contact just makes the door change position.

I already had a 433Hz setup using Sonoff RF bridge, so I use a simple door magnet contact to know if open or closed. Use a cover template to wrap it together in a single entity.

esphome:
  name: gdo2
  friendly_name: gdo2
  on_boot:
    priority: 300
    then:
      lambda: |-
        WiFi.setPhyMode(WIFI_PHY_MODE_11G);

esp8266:
  board: esp01_1m

# Enable logging
logger:

# Enable Home Assistant API
api:
  encryption:
    key: "XXXXXXX"

ota:
  platform: esphome
  password: "XXXXX"

wifi:
  ssid: !secret wifi_ssid
  password: !secret wifi_password
  min_auth_mode: WPA2
  
  # Enable fallback hotspot (captive portal) in case wifi connection fails
  ap:
    ssid: "Gdo2 Fallback Hotspot"
    password: "XXXX"

captive_portal:
    
switch:
  - platform: gpio
    name: "Garage Remote"
    pin: 5
    id: relay
    on_turn_on:
    - delay: 1000ms
    - switch.turn_off: relay

Thanks for the info! I was hoping for more of a plug and play solution as I do not have any experience with esphome stuff. I came across the Sonoff stuff and am looking to see if I can make it work for my sue case.

You can buy a RATGDO from here: ratgdo32 – ratcloud llc

It has all the necessary tools you need (including the esp board). Unfortunately the firmware is not preinstalled though. However this is relatively simple to install. Just connect the device to your computer via usb, and upload the firmware to it via esphome dashboard (or esphome flasher tool, if you don’t have esphome dashboard installed). There are also OTA options instead, but instead of me telling you how, you can simply read the instructions here: Firmware – ratcloud llc

I have bought this in the past (I have an older model board though, since he is updating the board regularly). And this works perfectly fine. I have even removed the chamberlain cloud controller entirely since I didn’t need it. The chamberlain/myq app is horrible anyways.

So basically 90% is plug and play, it is just the firmware and connecting part that isn’t. But with these instructions and prebuilt firmwares it shouldn’t be too hard.

I hope this will help you.

Thanks all…I ended up ordering a couple of shelly 1’s and will be setting them up tomorrow.

Hi Osyras,

I am curious if you got this working? I have a similar setup and I’d really like to be able to control the opener locally but I’ve not found anything to work yet.

Thanks,
