Diadema IDRO / Total Control app / uncloud to Home Assistant

"uncloud" La Nordica Extraflame Diadema IDRO / NAVEL 2.0 Wifi Modul to Home Assistant.

What has happened so far.

I can still record when something is sent to the stove. It's just that my programming knowledge is outdated (rusty). Well, here's what I've found out so far.

Total Control https://totalcontrol.extraflame.it or the new one i found in this log, http://wifi.extraflame.it

I opened the wifi adapter (white label). And found 3 pins on the ESP32.

GND is drawn, just need to find rx and tx. So in my case now (Blue = GND, Orange = RX, Yellow = TX) You need a 3.3v usb2uart. Note (green is not connected)

Then connect with putty, serial port of usb2uart, baud rate 115200.

I was very surprised that it is an esp32 wroom and there is a partition with spiffs.

extraflame.txt

Unfortunately I can't make a backup of the esp. I always get the error message A fatal error occurred: Failed to connect to ESP32: No serial data received.

esptool -p COM7 -b 115200 read_flash 0 0x400000 flash.bin

Instructions here

Then based on philibertc Philibert Cheminot i created the controller. https://github.com/philibertc/micronova_controller/wiki/How-to-build-it

after that, i got the software from Jorre05 Joris S and installed it on a Wemos d1 mini. changed some variables and it´s running.

Diadema_IDRO read write locations.

My Stove model is "Extraflame Diadema IDRO"

News:
Added a pellet level sensor.

Hardware components:
Wemos D1 Mini and HC-SR04 ultrasonic sensor.
HC-SR04:
Vcc to wemos 5v
Trig to wemos pin D4
Echo to wemos pin D3
Gnd to wemos Gnd

Reed sensor: A magnetic switch that closes when a magnet approaches and opens when it moves away. LED: A simple LED controlled via a GPIO pin of the ESP8266/ESP32. Resistor: A 220-330 ohm resistor in series with the LED to limit the current. ESP8266/ESP32: A microcontroller powered by ESPHome. Wiring: Reed sensor:

A reed sensor pin to GND. The other pin to a digital GPIO pin of the ESP (e.g. GPIO14) and at the same time to 3.3V via a pull-up resistor (approx. 10k Ohm). LED:

Anode (longer pin) of the LED to a GPIO pin of the ESP (e.g. GPIO5) via a 220-330 ohm resistor. Cathode (shorter pin) of the LED to GND.
