Tesla Charging automation in Home Assistant

I needed a super simple Tesla charging automation for Home Assistant to use energy from the Solar panels when producing.

What it does

When Solar power is above 1 kW for more than 10 seconds, and the charger is plugged in, then start charging If Solar power drops below 1 kW, stop charging

Its that simple.

Requirements

• Home Assistant
• Tesla
• Tesla Wall Connector

How to

• Discover and install Tesla Wall Connector
• Install Tesla Custom integration
• Go to Settings -> Automations & Scenes -> Create Automation
• Add the below scripts & adjust to your tesla and solar sensors for Home Assistant.
