AOJ-33B Tuya bluetooth blood pressure monitor

Third party integrations

I managed to link this blood pressure monitor to my Smart Life app.

Can this be linked up to the espHome BLE proxy?

Is it working?

Sadly no, do you this device too?

Smart Life app, where is this software? Is it Tuya app? . I have a new AOJ-33A with Bluetooth, manual recommend to use with VitaConnect app. Can I use Tuya App? So, I can link to my HA.

I have this from my esphome, any idea how to send the payload to MQTT for further decoding?

The device has a MCU that repeatedly transmits the payloads above (that does not contain any blood pressure information), waiting for the Tuya app to start the song and dance, this prevents us from getting the measured readings.

However the design seems to be very modular where measured readings are transmitted to the MCU via UART. So, it is very possible to intercept the TX and send it off to HA instead.

Can take apart your device and show images of the PCB inside? Front and back please.
From my understanding, AOJ-33A does not have bluetooth. only AOJ-33B does.
