Support for R503 FPS and watchdog
The adafruit fingerprint library supports FPM10A (optical) and R30x/R50x (Capacitive) Fingerprint sensors. However, the Capacitive fingerprint sensors (FPS) do not support the following function:
finger.fingerFastSearch();
The above line throws "Unknown Error" on Serial Monitor via switch-case logic.
but instead use
finger.fingerSearch();
The R-series FPS have an LED ring around the sensor that can be used to indicate various states via
finger.LEDcontrol(uint8_t control, uint8_t speed, uint8_t coloridx, uint8_t count=0)
I have also noticed that certain microcontrollers (ESP32xx family) get stuck and do not publish mqtt messages, even though broker and wifi are available. I am yet to ascertain the issue via logs as this bug appears only when microcontroller is on power (for an extended period of time - days) and not connected to a system for serial monitor. Currently using a watchdog to raise a hardware interrupt and reboot the device on such a scenario.
esp_task_wdt.h no such file or directory
I'm trying to compile : fingerprint-R503-mqtt-led-WDT.ino
But i can't get it to work on my wemos d1 mini.
I always get the error : esp_task_wdt.h no such file or directory
But how can i solve this error?
I really don't know where to find this esp_task_wdt.h

Reboot regulary
Hi
First thanks for your great work.
In my case, all work, learning deleting, matched...
i can open my nuki lock or unlock with him
but regulary my wemos reboot and i have this message

what is the problem, how i can fix it . Thanks
unknown error
Hi,
I'm using a Wemos D1 mini with a R503 Fingerprint sensor. The wiring seems to be correct and mqtt is working too.
I can learn new fingers but everytime i put my finger on the sensor i get this output
Found fingerprint sensor!
Connecting.......
Connected, IP address: 192.168.7.172
Attempting MQTT connection...connected
Image taken
Image converted
Unknown error
Communication error
It seems to happen in this part of the sketch
// OK converted!
p = finger.fingerFastSearch();
if (p == FINGERPRINT_OK) {
Serial.println("Found a print match!");
lastID = finger.fingerID;
lastConfidenceScore = finger.confidence;
return p;
} else if (p == FINGERPRINT_PACKETRECIEVEERR) {
Serial.println("Communication error");
return p;
} else if (p == FINGERPRINT_NOTFOUND) {
Serial.println("Did not find a match");
return p;
} else {
Serial.println("Unknown error");
return p;
}
Any idea how to solve the problem? I tired it with 2 different R503 and two different Wemos D1 mini
My wiring is
Red + White > 3,3V
Black > Ground
Yellow > D6
Green > D5
Blue > not connected
Not getting it to work with Oled
Hello,
when i use the first version fingerprint-mqtt.ino the sensor works perfectly.
i followedd your video and it works in home assistant too.
When i try any other version it doesnt. I did solder the extra wires 4 and 5 to D3 and 3v as written.
but non of the codes work with it. I am using a Wemos d1 mini for it with a OLED on pins D1 sda, and D2 scl.
Any idea what could be causing this?
(oled)automations.yaml dosent work
Hey there (:
So the automation didnt work for me
Of curse I config finger print 1
I think its to old to new HA version
Someone success to make that automation work ?
https://raw.githubusercontent.com/EverythingSmartHome/fingerprint-mqtt/master/Home%20Assistant/(oled)automations.yaml
Fingerprint matched but unavailable name
Hi,
I am using Home assistant in a virtual environment with the following:
Home Assistant 2022.10.3
Supervisor 2022.10.0
Operating System 9.2
Frontend 20221010.0 - latest.
I've used your code to set fingerprint and I recorded 3 of my fingers with different names but only the last one has a name available. The other 2 are unavaillable but matched.
I've used scripts.yaml and configuration.yaml but splited with sensors.yaml.
This is in configuration.yaml:
- name: "Fingerprint"
state_topic: "/fingerprint/mode/status"
value_template: "{{value_json.state}}"
json_attributes_topic: "/fingerprint/mode/status"
json_attributes_template: "{{value_json | tojson}}"
The rest is in sensors.yaml
What am I missing?
relay
Is there a version were you can connect a relay to use the sensor standalone without a internet connection but sends data when available?
I want to use the sensor in my garage were the internet conncetion is not always stable.
No createModel in class Adafruit_Fingerprint
When I compile I get the error:
/Users/username/Downloads/Fingerprint/fingerprint-mqtt-led-touch/fingerprint-mqtt-led-touch.ino: In function 'uint8_t getFingerprintEnroll()':
fingerprint-mqtt-led-touch:342:14: error: 'class Adafruit_Fingerprint' has no member named 'createModel'
p = finger.createModel();
^
exit status 1
'class Adafruit_Fingerprint' has no member named 'createModel'
I can indeed not find that function in the version of AdaFruit_fingerprint that I am using. Could it be that it is renamed to loadModel?
ESP01 not booting with his code.
Hello! I had wanted to run this code on one of many esp01's I had sitting around. I seems that whenever I put this code on them, It doesn't want to boot. It has no logs and doesnt do anything. I was wondering if anyone had success with using these small boards with this sensor. I am using GPIO pins 0 and 2. It does boot with other things like esphome and just a blink code but with this code, no logs. If anyone was successful and got it working, that would be very nice. I have also tried it on multiple boards with no avail.
2nd Sensor
Hi
Great project, finally implemented into my HA!
I would like to add second sensor to Home Assistant
What should be changed, to have 2 sensors in one HA instance?
in sketch, and in HA Configs.
also, what should be disabled in sketch when connection error triggers, that no red light flashes.
thank You in advance!
MQTT - learning
What is the mosquitto_pub message to start learning a new fingerprint?
Home assistant and the name of id
I
i ve a bug with the name of persnon.
When i learning a fingerprint ( ex ID 1 name John) with id and name it's ok
when i scan again the id it's good and the name of person same.. ID 1 Name John
Now when i learning a second finger, it's good ( ID2 name jack)
scan finger > name and ID ok : ID 2 Name JAck
But if i scan the previous finger the ID is good ID1 but name is "unavailable".
if The id is good i thing the memory and the module is good.
may be an error in the configuration of sensor in yam code.
Thanks
Configuration sensor/topic code depricated
Issue
When copy pasting your configuration.yaml code into HomeAssistant, the editor shows that your mqtt topic code is depricated.
Also after restarting HomeAssistant the logs show a warning regarding the same and is referring to:
https://www.home-assistant.io/integrations/sensor.mqtt/#new_format
Suggestion
#Fingerprint mqtt topic

Connecting a relay to work with solenoid
Is there a way to trigger a small 5V relay when the fingerprint is matched with the stored prints ??
