Python 3.7 for Home Automation

---

I got told to update my Pi3 for HA to continue running.
I am not sure how typical my system is, I just installed it using the instructions on the HA website and it worked.
These are my notes for next time:

sudo apt-get install build-essential tk-dev libncurses5-dev libncursesw5-dev libreadline6-dev libdb5.3-dev libgdbm-dev libsqlite3-dev libssl-dev libbz2-dev libexpat1-dev liblzma-dev zlib1g-dev

wget -O /tmp/Python-3.7.3.tar.xz https://www.python.org/ftp/python/3.7.3/Python-3.7.3.tar.xz

cd /tmp

tar xf Python-3.7.3.tar.xz

cd Python-3.7.3

./configure

sudo make altinstall

sudo apt -y autoremove

cd

rm -r /tmp/Python-3.7.3

rm /tmp/Python-3.7.3.tar.xz

sudo systemctl stop home-assistant@homeassistant.service

sudo mv /srv/homeassistant /srv/homeassistant_old

sudo mkdir /srv/homeassistant

sudo chown homeassistant:homeassistant -R /srv/homeassistant

cd /srv/homeassistant

/usr/local/bin/python3.7 -m venv .

source bin/activate

pip install wheel homeassistant

** Note I chose to run hass first time to see all the installation messages.**

sudo systemctl start home-assistant@homeassiith Python 3.7.3
