Inside of Tuya Fingerbot ADAPROX doesn't inspire me

alx-xlx · June 15, 2025, 1:10pm

I bought this Fingerbot (Bluetooth) and its been nightmare ever since. it was working well, and I could make it work again with those HACS repositories, but I don’t want to rely on anything from tuya cloud. And I am also facing the issue where the arm doesn’t retract. Some people are facing that issue with zigbee pair

So I opened up the back panel to see and its just a stupid board loaded with tuya bloatware that is all of my trouble. This thing is heavily over-priced. , I want to just slice that board off and put my own esp32 or esp8266 module in there. Has anyone tried to make it work without tuya.

Can this be flashed with esphome ??
What are my options ??

No.

You will also need some motor driver.
The problem would be battery life, Esp/Esphome are not optimized for battery operation.

It’s TUYA. You can’t make a silk purse out of a sow’s ear.

I had to use translator for that.
I totally agree for Tuya, but here where I live many people appreciate fried sow’s ear.

Ble version is running well offline without internet connection, so it is free of tuya cloud (after initial setup)

Nice! Can you explain better?

interesting, so I think I need to pick up soldering iron and fix it myself then.

so, Motor driver, esp8266 or esp32, and powersource. I will be using the fingerbot to power a device so it will be close to a powersource. I can simply give it external DC power. I think that should be enough ?

Do you think the zigbee version of the Fingerbot would have been a better choice ? OR do they require some sort of connection to tuya cloud as well ?

That will work. And easy to build and setup. Tiny DRV8838 module should be enough for that motor.

No. I personally haven’t played with those, but you find info on this forum.

If they are zigbee AND if someone has created a quirk for zha it will not connect to any cloud.

I am using Tuya BLE custom integration, which fetches device id and device key from Tuya cloud account (not changed over time) and home assistant communicates with device using Bluetooth only.

I have ESPHome devices acting as Bluetooth proxy so I can manage this device.
