This command line tool allows you to read and set the Powerwall minimum backup reserve battery level (percentage).
# Install python modules
pip install python-dateutil teslapy
# Login to Tesla account to set up token
python3 set-reserve.py --loginThis will create the config file, save an auth token so you will not need to login again, and then display the energy site details associated with your Tesla account. It will run in an interactive mode.

Cron Job Examples
See the cron.sh example script on how you can use set-reserve.py to optimize your Powerwall usage.
This command line tool allows you to read and set the Powerwall operational mode (self-powered or time-based control).
# Install python modules
pip install python-dateutil teslapy
# Login to Tesla account to set up token
python3 set-mode.py --loginThis will create the config file, save an auth token so you will not need to login again, and then display the energy site details associated with your Tesla account. It will run in an interactive mode. See the instructions for the "Set Reserve" tool above.

Set Operational Mode
# Set to Self Powered mode python3 set-reserve.py --set self # Set to Time-Based Control mode python3 set-reserve.py --set time
This python script allows you to change your Tesla car charging speed (amps) in realtime with solar production and home energy consumption (to minimize drawing and feeding power back to the grid), using PyPowerwall to get the energy data from the PowerWall local gateway, and TeslaPy to set charging speed via Tesla's Cloud API.
Modify the TesSolarCharge.py file and enter in your Tesla-associated email address (login), your latitude and longitude (as numeric with three decimal places), the IP address of the computer running PyPowerwall on your local network, and the hour of the day when you want charging to stop:
username = 'yourname@example.com' # Fill in Tesla login email address/account
lat, lon = ##.###, -###.### # Fill in Location where charging will occur (shown at startup)
pypowerwall_IP = '10.x.x.x:8675' # Fill in IP address and port for pypowerwall docker container
stop_charge_hour = 16 #hour of the day to stop charging (i.e. peak electricity rates to not discharge powerwall or when solar production expected to be around min charging rate causing charging to start and stop frequently
Install Python modules and try to authorize TeslaPy
# Install python modules
pip install teslapy
# Login to Tesla account to set up token
python3 TesSolarCharge.pyThe first time you run the script if TeslaPy is not authorized, it should provide a Tesla website URL, where you can login with your Tesla account credentials.
NOTE: After you log in, it will take you to a 404 Page Not Found error page - do not panic, this is what you want.

# Run TesSolarCharge.py to start charging your car and adjusting rate based on solar python3 TesSolarCharge.py
These tools (set-reserve and set-mode) are based on the the amazing tesla_history.py tool by Michael Birse (@mcbirse) that imports Tesla cloud history into the Powerwall-Dashboard.
TesSolarCharge is based on TesSense w/ SenseLink by Randy Spencer (https://github.com/israndy/TesSense), modified by Nate Carroll to work with PyPowerwall and add a few features.
