Hi guys.
I have some problems with fingerprint and MQTT. I followed this article:
https://everythingsmarthome.co.uk/how-to-build-a-wifi-connected-fingerprint-sensor-with-home-assistant/
I set it and make it work but I found out that after some time, it is not reading any fingerprint
In mqtt it is not reading every 5 seconds as it sould but it is stuck at one reading....
This is the correct reading (mqtt_after_restart.png) and is working fine after a fingerprint sensor restart up to some unexpected error,
and this is what I find after the error (mqtt_before_restart.png).
Yesterday I found a record in logs that fingerprint ID is waiting an int and received "unknown".
I deleted all the fingerprint records and learned only 1 finger. It worked for about 1 hour and stoped with no errors in logs.
I reset it and it worked but today, in the morning, when I wanted to open the gate it didn't work. No errors in logs.
Any iddeas?

How to build a WiFi connected Fingerprint Sensor with Home Assistant

When I posted some update videos on Reddit
[https://www.reddit.com/r/homeautomation/comments/gquzmc/quick_update_on_the_fingerprint_sensor_remotely/]
and Twitter [https://twitter.com/EverySmartHome] (make sure to follow me there
for more updates!) earlier this week about the Fingerprint Sensor update, the
reaction was so

Hi, which version of the fingerprint sensor do you have?

Did you solve your issue?

# balmy crypt Depending on the version of the sensor, you could use ESPHome instead. That’s wh...

@balmy crypt, that's what I asked Lewis yesterday! I decided to go forward myself with integrating a Fingerprint Sensor following his tutorial and I am wondering if going through the Arduino IDE route is still the recommended way to go. I've seen there is a Grow Fingerprint Reader component on ESPHome. Could this allow us to mount the required libraries on a WeMos D1 Mini without using Arduino IDE??

I think I have the same model as Lewis used:

@balmy crypt, in 8 hours, let me know if your config can work with this finger model eshnoice

What I notices is that after reading a fingerprint, the "waiting" status keeps showing "confidence" and "match"...

#

mine got stuck again today, after a few working days...

that yellow line is like this since noon today

#

and it started to read after I pressed "Enter"

@balmy crypt, you wanted a reminder? Here it is!

Have a sec 🙂

Take your time

I almost forgot haha

Sorry for the bad wiring scheme! Lol

When I left home this morning it worked... I wonder for how long...😆

Probably an FPM10A like mine. Take your time and let us know 🙂

@bleak radish Still stable?

bleak radish
#

Hi. No. Needs restart of the fingerprint once or twice a day

#

Strange is that there's no errors in the log

#

I hope I don't run into the same issues... I'll keep you updated. Thanks @bleak radish

I don't know by what miracle, I didn't restart the fingerprint for about a week and still works. It takes 5-7 seconds to read my fingerprint but it works. I recorded same finger twice but with different name and seems that it works. It reads the first one recorded but is seems that takes 2-3 second to read. I'll check again tomorrow.

#

This is my setup:

#

I also have a Sonoff Zigbee button that works way faster but I want to use this since is right next to exit...

#

Outside I have a Dahua VTO2211G-WP video doorbell with RFID keys and I tried to use face recognition (Frigate, Double-take and Deep Stack) but I had a lot of false positive faces that would open the gate and I gave up. Dahua doorbell has face recognition but I did not find how to integrate that in Home Assistant. Maybe in the future...

Hello again!

#

Regarding fingerprint error I wrote above, it still not working but I found in logs something about fingerprint_id that is expecting an 'int' and receiving 'unknown'.
I checked the sensor.yaml code and changed the following:

#

from (int):
value_template: >-
{% if states('sensor.fingerprint_id') | int >= 1 %}
{%- set printid = states('sensor.fingerprint_id') | int -%}
{%- set prints = states("input_text.fingerprint_data") | from_json if states("input_text.fingerprint_data") else [] -%}
{%- set fingerprint = prints|selectattr('id', 'eq', states('sensor.fingerprint_id') | int(0)) | first -%}
{{fingerprint["name"]}}
to int(0):
value_template: >-
{% if states('sensor.fingerprint_id') | int(0) >= 1 %}
{%- set printid = states('sensor.fingerprint_id') | int(0) -%}
{%- set prints = states("input_text.fingerprint_data") | from_json if states("input_text.fingerprint_data") else [] -%}
{%- set fingerprint = prints|selectattr('id', 'eq', states('sensor.fingerprint_id') | int(0)) | first -%}
{{fingerprint["name"]}}

Now I have to get home to restart the fingerprint module and, maybe, by a miracle.... 😀

It worked one day and now everithing is back to "normal"
