Requirements
|
||||
--------------------------
|
||||
* Requires "blue wire" compatible heater unit
|
||||
* Blue wire interface circuitry
|
||||
* Blue wire interface circuitry - please refer to the hardware design schematics in the wiki for guidance.
|
||||
It is important to take note that the blue wire is 5V logic, an ESP32 is 3.3V.
|
||||
Level translation is important!
|
||||
* ESP32 dev module
|
||||
* HC-05 Bluetooth module - preferably exposing the key pin, not power control)
|
||||
* DS18B20 one wire temperature sensor
|
||||

@ -31,14 +33,17 @@ Working so far:
|
|||
* 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
|
||||
* Two timers - including selectable day and repeat functionality
|
||||
* Battery backed Real Time Clock - DS3231
|
||||
* Prototype "Green PCB" in production, using naked ESP32 and HC-05 modules
|
||||
* Temperature readout in Celcius or Farenheit
|
||||
|
||||
To be implemented
|
||||
--------------------------
|
||||
* Add 2 external digital inputs, 2 digital outputs, analogue input 433MHz Rx stream, 433MHz Tx stream connections. This would allow external timer units for example, or analogue temeprature demand (which is still only 1 degree resolution).
|
||||
* MQTT pub/sub
|
||||
* "fuel gauge" - Integrate pump frequency, assuming a repeatable dose of fuel per pump cycle...
|
||||
* Proper 7 day timer with each day settable for at least 2 times (eg morning/evening)
|
||||
* Expand hardware compatability with different MCU setups. IE Arduino Due/Mega/Pro ESP8266 & ESP32
|
||||
* Documentation
|
||||
* Regular Hot Burn cycle (DPF mode!)
