micronova_stove_esphome

Three sub-projects for connecting a home automation system to ARTEL IDRO15 PelletStove.

1. Kicad PCB for 'ESP32 mini D1'.
2. Arduino-code for reading all RAM- and EEPROM-registers easily.
3. ESPHOME-yaml for connecting the PelletStove to e.g. Home Assistent or OpenHAB.

Contained projects:

1) Kicad stove-reader-pcb

A Kicad project for PCB to fit an 'ESP32 mini D1' to communicate with a PelletStove having a MicroNova compatible serial interface.

The PCB has JST-XH2.54 connectors for

• 2x I2C devices
• 2x external DSB18B20 temperature sensors
• 1x for power conversion
• 1x pelletstove serial

2) Arduino stove-ram-reader

I created it to find the correct address of the Fume-Temperature address for my stove type.

Works in combination with the PCB. Code is for ArduinoIDE 2.x to program an 'ESP32 mini D1'. Program to interrogate the RAM and EEPROM registers and publishes it via its webserver. Its address is published via mDNS as esp32.local Webserver can be accessed at http://esp32.local/

Uses a version of:

• micronova_stove.h code from https://github.com/eni23/micronova-controller
• micronova_stove.cpp code from https://github.com/eni23/micronova-controller

3) ESPHOME yaml

Works in combination with the PCB.

YAML which interfaces with

• OLED screen for local readout (i2c OLED 128x32).
• Pellet level sensor (i2c VL53L0X time-of-flight infrared distance sensor).
• External temperature sensors (In below image the DSB18B20's are not connected).
