Follow the next steps to control your thermostat with a raspberry pi

For hardware connection see:

Create a ssh connection to your pi

ssh pi@192.168.x.x

Step A: Create a new directory into your home directory and change to this one

mkdir a
cd a

Step B: Check if you are in the directory "/home/pi/a"

pwd

Step 1: Download these two repositories

git clone https://github.com/ThomasMoellerR/MQTT_Thermostat.git
git clone https://github.com/eclipse/paho.mqtt.python

Step 2: Install MQTT module for python3

cd paho.mqtt.python
sudo python3 setup.py install
cd ..

Step 3: Install tmux

sudo apt-get install tmux

Step 4: Install a new crontab by append the @reboot line

crontab -e

@reboot /bin/bash /home/pi/a/MQTT_Thermostat/tmux.sh

Step 5: Make tmux.sh executable

sudo chmod +x /home/pi/a/MQTT_Thermostat/tmux.sh

Step 6: Configure MQTT settings for your thermostat

nano /home/pi/a/MQTT_Thermostat/main.sh

Step 7: Reboot your Pi or start the tmux session manually

sudo reboot

or

bash /home/pi/MQTT_Thermostat/tmux.sh

--> Finish: When you arrive at this point, you are done

Troubleshooting:

A: Set the Termostat to the operating state "manu" (see Youtube video)

B: Turn the encoder one step to the right or left (see Youtube video)

C: Check if the programm is running

with the command "tmux a" you can attach to a running session

tmux a

with the command "ctrl+b" inside the session with a "d" followed you can detach from this session and the programm keeps running

ctrl+b

d

If the session is not running, try Steps 4, 5 and 7 again.
