BluetoothHeater
Bluetooth & WiFi interface for Chinese Diesel Heaters
Requirements
- Requires "blue wire" compatible heater unit
- Blue wire interface circuitry
- ESP32 dev module
- HC-05 Bluetooth module - preferably exposing the key pin, not power control)
- DS18B20 one wire temperature sensor
- 1.3" I2C OLED using SH1106 controller
- DS3231 Real Time Clock
- Technical ability to solder SMD components
- Technical ability to program/flash in the Arduino environement
Working so far:
- Power On/Off
- Temperature + & -
- Fuel mixture tuning
- One wire remote temperature sensing (DS18B20)
- Heat exchanger body temperature, as reported by heater unit
- I2C Interface to 1.3" SH1106 based OLED for a full featured controller
- 5 button keypad interface
- Smart error detection, observes unusual heater state progression (ignition fail)
- ESP32 with HC-05 Bluetooth
- JSON based communications between Bluetooth and Wifi apps
- Bluetooth Connectivity
- Bluetooth Control App for Android (App Inventor based)
- WiFi Connection to existing network or Standalone Access Point Mode (Passwd: thereisnospoon)
- Wifi control
- DebugPort data sent via Telnet if/when available on the network.
- Two 7 day timers - including repeat every day functionality
- Battery backed Real Time Clock - DS3231
- Prototype "Green PCB" in production, using naked ESP32 and HC-05 modules
To be implemented
- MQTT pub/sub
- "fuel gauge" - Integrate pump frequency, assuming a repeatable dose of fuel per pump cycle...
- Expand hardware compatability with different MCU setups. IE Arduino Due/Mega/Pro ESP8266 & ESP32
- Documentation
- Regular Hot Burn cycle (DPF mode!)
- list under construction.....
