Hi, I did a DIY opengarage Garage opener (a nodemCU plus HC-SR04 ultrasonic sensor)
and flashed this firmware:
It works great, but wish to bring everything ESP related flashed with ESPhome, has anyone a working yaml code for it?
Thanks
Thank you, very useful.
In case anyone is interested and finds this older post via search I thought I would show my take on converting the same parts used for the OpenGarage DIY to be used for ESPHome. It doesn’t provide a web page frontend but it does pretty much the same job.

Hey I was curious if you’ve made any modifications to this since its been a while, I’m about to follow suit myself.
Still the same code being used for my setup.
Hi There. If i have to add MQTT to this and publish all this by MQTT, how will i do?
I went with something similar but with a few differences:
- I enabled the beeper when closing
- I enabled an auto-close feature (this only enables if the door was opened by the module as I didn’t want it to enable if I manually opened the door, you could change this)
- I found the distance sensor to have moments when it reported wrong values so I used ESPhome to smooth out the values. I also throttled how often it reports by setting a threshold
- I check the distance before invoking open/close to ensure it isn’t already in that state and therefore ends up doing the opposite to what I want
I’m new to ESPhome so there may be better ways to do what I did below.

Does this work with the latest version of opengarage hardware? when i flash this, it just bricks and doesn’t boot up.
./Sooraj
Define please?
I’m not sure what version mine is, I bought it back in January of 2020 and it looks the same as the version in the photo they have in the store with the acrylic case.
What steps did you take to flash it? Was it through the OpenGarage web interface?
I compiled the yaml in esphome, downloaded it and upgraded via the web interface. it said upgrade successful, but nothing turned up in my network. The hardware that i have, the chip covering says ESP12n. seems to be a derivation of ESP8266EX. How did you loaded? via the serial interface? as the model that i have dont have the serial to usb chip and has to be reflashed using FTDI adapter.
looks like the latest version of hardware that they sell dont have the serial to usb chip. so if i have to reflash it, i have to do it via the FTDI adaptor, like how we flash old sonoff devices.
I loaded via the web interface. If the device did not show up on your wi-fi, did you ensure that it isn’t broadcasting its own AP?
Yup. tried everything.
Could you also tell me if the code above will detect if the car is in the garage or not? i didnt see any status for the same when i read through the code. Also how can i publish the whole status and control everything via mqtt rather than ha api, as the garage is in separate network.
Unfortunately, you’ll likely need to try a serial flash then.
The code above will not check for vehicle presence. You’d have to make some changes to do that, perhaps create a template sensor in ESPHome that evaluates the ultrasonic distance and sets the vehicle status to true if the distance is greater than the garage open distance but less than or equal to the distance threshhold to the top of your car. See: https://esphome.io/components/text_sensor/template.html
If you don’t want to use the native API, you can use the MQTT client component instead: https://esphome.io/components/mqtt.html

My OpenGarage also ended up in a bootloop. I have this version, please note the wifi shield being under the ultrasonic sensor:
The bootloop comes from the wrong pinout. The correct pinout for this version is listed here:
/** GPIO pins */
#define PIN_RELAY 15 //D8 on nodemcu
#define PIN_BUTTON 0
#define PIN_TRIG 12 //D6 on nodemcu
#define PIN_ECHO 14 //D5 on nodemcu
#define PIN_LED 2
#define PIN_RESET 16
#define PIN_BUZZER 13
#define PIN_SWITCH 4 //switch sensor: D2 on nodemcu
#define PIN_TH 5 //temeprature sensor: D1 on nodemcu
Just use the numbers instead of the Dx.
PS. To add a nice ring on boot:
