🚘 Garage Fingerprint Sensor

[parrel]

Try to use the entity directly instead of the device

[Andy089]

I’m trying to create in Automation…
trigger
Trigger Type → Device
Device-> Fingerprint_grow
Trigger → no selection possible

[parrel]

Select “Zustand” (state) and select the finger id entity.

[Andy089]

Okay thanks!
Thats how it works!

[Andy089]

Would one exist to put the ESP in DEEP SLEEP and use the R503 as a button to wake up?

Would be interesting for battery operation.

[parrel]

You could try it but I don’t think it will be very efficient.

The sensor would need to be powered and then you can use the WAKEUP pin of the sensor to wake up the ESP

But then the question is if you can read the result of the sensor in time

Not tested just thinking out loud

[Andy089]

Ok, I think I’ll give it a try.
I will then share my experiences.

Just made this project with D1 mini instead , and made a 3d model for it!
Here it is:
D1 Mini R503 Finger Print Sensor Box

@GuyZipory

roject with D1 mini instead ,

base on ESPHome ? or do you find a nother way?

EspHome on HomeAssistant

[007DJ (Roger "DJ" Moore)]

@parrel That sound like such a fun and interesting project. I am semi-fluent in yaml but I will confess I have never integrated ESPHome. When I started searching the internet for the parts I got so many variations that I question compatibility. Any chance I could talk you into sending me links for the required hardware? The other question… In ESPHome, how does the ESP8266 communicate to HA? I currently have WiFi and ZWave via SmartThings. Would I need a new hub?
Again, I think this is a awesome project and I am extremely interested in duplicating your achievement if your able share hardware links and you great wisdom
Thanks in advance!!

[parrel]

Hi, if you don’t know which part to pick, just comment here. The links are in the original post.

An esp8266 has a wifi chip and connects to home assistant via wifi (just like your phone). You don’t need a hub for it.

Home assistant and the esp have to be on the same network.

[007DJ (Roger "DJ" Moore)]

@parrel … Sorry to have troubled you. I did read your post carefully. The only link I found was Aliexpress and I selected one of the 3 sensors, mounting plate, and a flip cover weather protector. I could not find a link for ESP8266 or ESP32. As I tried to communicate, I found so many listings and brands but could not find the one you had in your image. As previously stated, I was worried about compatibility. After my complete topic re-read, I have made another assumption that is likely to send me into a tailspin… is the config you listed in configuration.yaml, ESPHome Integration, etc. You stated that the device itself stores the approved fingerprints, but not how to record them. Do I assume that is supplied by mfg Aliexpress?

@parrel

Once that’s done, load the ESPHome config on the ESP. This is my config.

Again, I don’t mean to be a hassle, and I would bet I have complete understanding by the completion, but this is all new and I hesitate only because I have crashed my HA in other attempts to do really cool things, and not I am somewhat dependent on it to remain operational . BTW, I ordered the Sensor, cover, and weather cover… expected mid AUG. Thanks again for taking your time to share. It IS appreciated.

@Mikefila

In developer tools under the services tab enter esphome.(your.nodes.name)_enroll then in data add

{ "finger_id": 0, "num_scans": 2 }

Where finger_id is the slot it’s saved in.

Then call the service. Its helpful to go split screen to lovelace to see what the sensor is doing.

It creates an enroll service. It can be called through an automation or script as well.

[parrel]

Hi,

It does not really matter which esp32 or esp8266 you take as long as it has the required pins. I would suggest the nodemcu or d1 mini

Make sure to read or watch some videos on how ESPHome works.

Like @Mikefila says, you can store the fingerprints by calling a service.

[Protoncek (Pavel)]

Yesterday i wired this sensor myself, too. It went alive at first try, luckily (big thanks to author!!). After showing device in HA you go to developer tools and call service for enroll, select id0 and number of readings - i selected 5, so that it’s more likely that finger will be recognized even if it’s not exactly at the center of the reader. Run service and press finger on reader until finished.

What i don’t quite understand is why author decided to use D0, which is GPIO16 (=wakeup pin) as communication…I’ve chosen GPIO4 and GPIO5 for comm, and one of GPIO12-14 for sensing pin.
But, basically, it really doesn’t matter which pins you use as long you have them available on board. Generally on ESP8266 it’s best practice to use GPIO0’s 4,5, 12,13 or 14.

Personally i hate these “custom” markings (that’s D0, D1…). I rather work with GPIO’s. It’s way more clear, universal… you can’t go wrong by defining pin like: GPIO4, while you can with Dx, if that Dx is not pin you thought it is… (different board, (too)cheap china clone,… for example) - been there, done that…

[Protoncek (Pavel)]

One question:
when i run service to enroll finger from HA, nothing happens on the sensor to indicate it’s ready for enrolling, so in real world i’ll have to shout from my PC (inside a house) to a person (outside) behind sensor to start enrolling .
Is it possible to add a command which would, say turn on PURPLE flashing (or anything…) right after service is triggered? Purple is shown between scans, that’s perfect, but it would be nice if it would also show status “prepared for enrolling” at the beginning…

Any suggestions?

[nickrout]

@Protoncek

so in real world i’ll have to shout from my PC (inside a house) to a person (outside) behind sensor to start enrolling

Do you not have a phone or a tablet?

[parrel]

Yes you can use the fingerprint_grow.aura_led_control function in the service aswell

[Protoncek (Pavel)]

Sure i have… and i bet i’ll use that to prevent “shouting” (that was kind of “intended exaggeration” from my side )
But, in any case it’s nice to see if/when device is ready for learning, don’t you agree?

@parrel: how? If i add to existing service compiler say i can’t have two items there…
