Ideas and help setting up EV charging automation in and off-grid environment

First, this is not a question about blueprints, so that blueprint tag in the topic really doesn’t belong there.

Let me search that for you…

Using excess solar power to heat swimming pool

This is a simple project to heat a swimming pool using excess solar power. It’s my first attempt with Home Assistant and it was surprisingly easy to do once I’d figured out the basics of YAML syntax. It’s also my first forum post so apologies for any rookie mistakes. I have rooftop PV solar and a swimming pool heated by a heat pump. A single water pump is used to both filter the pool and push water through the heat pump when it’s heating. Here in Australia the power companies buy excess power…

PV / Solar Excess Optimizer: Auto-control appliances (wallbox, dish washer, heatpump, ...) based on excess solar power

Hi everybody, I used the power of pyscript and the easy-to-use-approach of blueprints to implement an extensive solar excess optimization, which lets you auto-control your appliances based on power excess of your PV / solar system. Please let me know if you have questions, if you do encounter any bugs, or if you have feature requests. For the last two topics (bugs & feature requests) you can also directly raise them on my GitHub repository: PV Excess Control PV Excess Control Automatically…

Charging Tesla with excess power from solar panels

Hi, I am trying to set up an automation to charge my Tesla with excess power from my solar panels. Every 30 seconds (in the daytime, and if the car is plugged in) the export or excess power from the house electricity meter (pow_k) is measured. The idea is to keep the export power close to 0, by adjusting the charging amps of the car. If it is above 688w, the Tesla charging amps will be increased by 1. If it is below, they will be decreased by 1. HA gives the error message Message malformed: ex…

DIY smart grid: EV (Tesla) charging on excess solar power production

After browsing a couple of solutions for this, I figured out how to make my EV charge on excess solar power production (when available). After automating the process of adjusting the charging power to the current grid power state, I’ve added some functionality to optimize the usage. I’ve tried covering basic usability and some added usability scenario’s. Let me take you through the steps. Here’s what I started with: a smart power meter (using the DSMR integration) that shows the total grid po…

and seriously another dozen or so just here in the HA community. I didn’t even check Google.
