Tuya BLE integration, includes fingerbot

Hi all,

I’m working on Tuya BLE integration.

The starting point was this GitHub project: GitHub - redphx/python-tuya-ble: Python library to interact with Tuya BLE protocol

For now, I have almost working integration. The integration works locally, but connection to Tuya BLE device requires device ID and encryption key from Tuya IOT cloud. It could be obtained using the same credentials as in official Tuya integreation.

Supported devices are: three models of fingerbot and two different sensors. Here is a screenshot of interface:

I am interested in how many people have Tuya BLE devices and are interested in the integration.

Hi, I’m Interested in this, I got a Tuya BLE Smart Lock, any chance to make it work locally? im happy to help with integration if there’s anything i can do.

I have a Fingerbot Plus and would like to have it working with Home Assistant. It doesn’t work with Tuya integration.

Hi, thank you.

I think it’s possible if the lock is really BLE. I’ve bought a lock from Ali and it’s works via Bluetooth Mesh protocol. Unfortunately, BLE and Mesh are completely different. Have you tried to install the integration? Has it discovered your lock?

Have you installed the integration? Has it discovered your device?

Sorry for late reply, I was dealing with 500 internal server error issue. today after i updated the home assistant OS to 10.1 i could finally add the integration on second try :smiley: ,
so I have a Tuya Bluetooth gateway, before i unbind the device from Tuya gateway it actually discovered the lock in configuration section of integration, but the loading sign was keep spinning for a while and did’nt actually give me any error, so i had to cancel it,

after unbinding the lock from gateway, it just discovered the gateway and not the lock anymore (the mac address titled device in the photo), i also tried unplugging the gateway to see if it will discover the lock again but no luck…

here’s some details from my smart lock on Tuya IoT :

ive checked out the DP id’s for example ble_unlock dp id is 6,

it would be awsome if you can include the lock in this integration, i’ve been searching for the past month to find a way to get it to work with home assistant i’ve seen hundreds of posts about it :smiley:

Thanks!

UPDATE1:
so after removing the lock of my Smart Life app, and re-adding it, still didn’t work, but when i turned off my phone bluetooth, so it was added to my account but surely wasn’t connected to my phone via bluetooth, surprisingly it just poped up on my devices and integrations page :flushed:
but it is still stuck on configure screen (Loading forever) :

UPDATE2:
Finally!! added the config after 30mins (technically it didn’t) , now i can see the device and it says Fail to Setup,

Thank you for comprehensive information and logs.

To add device to the integration, id’s of all DP are needed.

At this point, I have no idea how to deal with these RAW datapoints.

It’s only one file of documentation about Tuya BLE API which is available for now (I’ve read it using Google Translate). There is mentioned that unlocking of the lock requires additional request to Tuya IOT Cloud for each opening. However, I have no idea how to use “instruction” received from cloud.

It is also important to ensure that the lock doesn’t use Tuya BLE protocol version 4. I’ve implemented only protocol version 3, because I have no devices with protocol version 4 to debug. It’s not so big deal, but I don’t like to write code which I can’t check.

Thanks for Looking into it,
looks like that those RAW datapoints are for Creating Password or unlocking via password, which i dont think needs to be integrated home assistant anyway (or it would be hard to do so, like you said need to be send to cloud and go back to lock again and that would not make sense because all this effort is to try to control the lock locally!)
i think having these entities integrated would be more than enough:
(Control, Alarm, Battery Monitor and maybe Beep Volume)

wrong_finger,

And about the Bluetooth version im not sure, i tried searching in the smart life app and Tuya IoT platform device section and API Explorer, unfortunetly i didnt have any luck finding the hardware’s bluetooth version, is there a way to check bluetooth version when my android phone is connected to the lock via bluetooth??

also im gonna dump some logs here hope you don’t mind, it might help developing a solution: :smiley:

these are the some errors and warning logged to HA since last night that i tried to add the lock,
at the moment i can see the lock in devices section but it says" Failed to set up

Thanks Heaps!

Hi Alex
Thank you for doing this integration.
I got it working on my test HA setup. I then removed it from there, and added it to my main HA box (HAOS).
I get this error:

I set up a new Tuya project (client ID / secret) and the same issue…
Any ideas? I don’t see anything in the HA log… is there anything I can do to help trouble shoot this?
Thanks
Andrew

Thanks,

It looks like your BT adapter doesn’t see your device. Try to move your device closer to check it.

Hi Alex
Thank you! You were of course correct :slight_smile:

So with that solved, can we use a ESP32 as a ‘BT range extender’ with this? Will bluetooth proxy by ESPHome work?

bluetooth_proxy:
  active: true

Yes, I’ve tested one of my devices (Soil moisture sensor) with ESP32 based proxy.

I’ve used the site ESPHome Bluetooth Proxy to flash my ESP. If you like to flash it manually, parameter ‘active’ must be true.

Thanks very much! ESPHome BT proxy working with ESP32 and an Adaprox fingerbot :slight_smile:

I’m going to first attempt to add your device to the integration. I think it’s better to open an issue in the GitHub repository and continue our conversation there.

Will Do, Thank You! :slightly_smiling_face:

I am definitely interested, I have several LED recessed lights that use the Tuya BLE and my Home assistant Tuya integration broke when my free account expired. Such a pain. I would love to get local control of these.
I have a Bluetooth hub that came with the lights.
Let me know what I can do to help.
Thanks!

Hi,
