Need a instruction how to start the script with a newstart of the raspberry pi and after an com. failure of the script. about bmspace

Glad you got it working. Back in the day I ran my scripts as system services using systemd. It also would restart the script if ever failed.

To address the second part of this issue I am running bms.py in screen, in a while-true loop. This restarts the script whenever the mqtt server disappears, which makes the script crash.

~/bmspace $ while true; do python bms.py; sleep 10; done;

I believe the correct way to start and restart the script would be via systemd, but otherwise a docker container (docker compose script) with the restart unless stopped flag should work too.

I changed my script to run in Docker.

Installed Docker on RaspberryPi

https://docs.docker.com/engine/install/debian/#install-using-the-convenience-script

curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh get-docker.sh

https://docs.docker.com/engine/install/linux-postinstall/
sudo usermod -aG docker ${USER}
log out, log in
docker run hello-world
sudo systemctl enable docker.service
sudo systemctl enable containerd.service

sudo reboot

Build image and run container

docker compose build
docker compose up -d
