pyHeatpump/staging/dev/INSTALL

# Install instructions

## Resources

You'll need a rasbpiOs image, and the kernel and dtb for qemu 

## Procedure

### Enlarge img

The downloaded img is resized on the SD card during the installation. We will need more space on the img. Qemu has command for that :

```
qemu-img resize rpi.img +1G
```

Install dependencies :

```
apt install git sqlite3 python3-pip python3-click python3-requests python3-netifaces python3-serial
```

Deploy pyHeatpump. Replace MONITORING_SERVER with the address of your server :
```
mkdir /var/lib/pyheatpump
echo 'pip3 install --upgrade git+https://git.yannweb.net/cli/pyHeatpump.git' > /var/lib/pyheatpump/pyheatpump_upgrade.sh
chmod +x /var/lib/pyheatpump/pyheatpump_upgrade.sh
/var/lib/pyheatpump/pyheatpump_upgrade.sh

cp db/*.sql /var/lib/pyheatpump/
