Brink-flair-modbus

Modbus RTU communication with ESP32/ESP8266 and ttl to rs485 module, to use in home assistant / esphome

Platforms

Currently supported ESP32 and ESP8266 platforms. By default ESP32S3 is used. If you want to use ESP8266, edit file esphome/brink.yaml, comment out esp32 include and uncomment esp8266 include file.

# Choose the correct type for your Brink model, so the correct max flow can be setup with a slider.
# In order to use other language or a different ESP chip, fix file names below.
# Currently supported languages are en, nl. 
# ESP32 is a mh-et-live or wemos d32 mini, esp8266 is a wemos d1 mini, esp32s3 is a lilygo ESP32S3-T7
# Be carefull not to upload the wrong code to the wrong chip. This could brick your ESP chip.

Translations

Currently supported languages are en, nl. In order to change language, edit file esphome/brink.yaml, and change include file (esphome-/.brink-labels-.yaml)

Custom sensors

Project support additional sensors DHT22 or M5stack SCD40/41, CO2 sensor or M5stack ENVIII humidity, temperature, pressure sensor. In order to enable them, edit file esphome/brink.yaml and uncomment include file for sensor.

Modbus addres inside brink.yaml

The modbus address is now configurable in brink.yaml. Because there are several Brink versions available on the market, like the Viessmann Vitovent 300w (H32e C400) which uses address 70
