Introduction

This page is about reverse engineering the BT-785, an inexpensive Tuya-compatible water electrical conductivity (EC) meter.

It measures EC and temperature, and has a display and communicates its reading over Bluetooth Low-Energy (BLE) to the Tuya app on a phone.

The goal is to understand the communication protocol so we can communicate with it from the raspberry pi in the [Karaburan] project.
