Wm66 Brew

We turned the GDR washing machine "WM66" into an brewing kettle.

Setup

This and this served as an inspiration, but we control the heating and the agitator of the wm66 via a relay with a raspberry pi 4.

the pi is flashed with Raspberry Pi OS Lite (32-bit)

this is used to create an hotspot with the raspberry pi. In our case the SSH connection is established with:

ssh pi@192.168.1.1

this is used to create a influxdb database

this as an example for influxdb database creation and user creation

get pip and git

sudo apt install git
sudo apt-get install python3-pip

The temperature sensor DS18B20 is connected to the raspberry pi like this and implemented with the wm1thermsensor python module.

pip3 install w1thermsensor

Enable 1-Wire in Interfacing Options in raspi-config
