<\/figure>\n\n\n\nWhat You Need to Get Started<\/h2>\n\n\n\n
To use this feature, you obviously need a solar energy setup (though direct solar production measurements aren’t strictly required), a sensor to measure your power grid import\/export, and smart devices to control.<\/p>\n\n\n\n
The most accurate way to calculate excess energy is by monitoring the grid directly. While you can<\/em> use your solar production sensor, your grid export<\/strong> is the true metric of excess\u2014it shows exactly what you are selling back after your home’s baseline consumption has been met.<\/p>\n\n\n\n Along with these sensors, you will need the AIO Energy Management integration for Home Assistant, which can be installed via HACS.<\/p>\n\n\n\n This is the core concept you should understand when setting this up. In the Excess Solar configuration, you define your grid sensor and assign it a buffer (in watts). You also define the devices you want to control, along with the power they drain when active.<\/p>\n\n\n\n When the grid sensor detects enough surplus power (buffer included), it will turn on the first available device it has the capacity to run.<\/p>\n\n\n\n Here is how the smarter logic handles the details:<\/p>\n\n\n\n Configuration can be done via legacy YAML or directly through the UI. I’ll walk through the UI method here. (If you prefer YAML, check out the\u00a0 Once the configuration is complete, some entities are automatically provided by the integration:<\/p>\n\n\n\n Each device then are provided with three entities:<\/p>\n\n\n\n Because not all controllable devices are simple smart plugs, you need to write an automation to follow the binary sensor. For instance, my bathroom floor heating is a climate<\/em> entity, so I need to raise the target temperature when there is excess solar, rather than just flipping a switch.<\/p>\n\n\n\n Here’s an example of a single on-off automation I’m using for my water heater:<\/p>\n\n\n\n And here’s the thermostat automation. I’ve created a scene for hi and low states of the thermostat that this automation will activate when surplus energy is provided.<\/p>\n\n\n\n (Tip: You can combine all these triggers into one massive automation if you prefer. You can check out my full YAML<\/a> setup on GitHub, which handles my spa, floor heating, and water heater).<\/em><\/p>\n\n\n\n So far, this feature has been working brilliantly for me\u2014I’m hitting up to 80-95% self-consumption of my solar! Your results will depend heavily on your solar capacity and the devices you have available to act as energy sinks.<\/p>\n\n\n\n This is just the beginning for the Excess Solar feature. There is still plenty of work to do, and I’m sure a few bugs will pop up in the wild.<\/p>\n\n\n\n What is currently missing? Right now, it doesn’t gracefully handle flexible-consumption devices, like EV chargers. In theory, you can set the minimum power to the triggering status and pass the flexible consumption entity as a parameter. However, in my case, my go-e charger has its own built-in solar tracking. If I run both the charger’s native solar logic and the AIO Excess Solar logic, they fight each other. That\u2019s a puzzle I definitely need to solve in a future update!<\/p>\n\n\n\n If you have ideas for improvements, find any bugs, or want to suggest new features, drop a comment below or open an issue<\/a> on the GitHub project page<\/a>.<\/p>\n\n\n\n The AIO Energy Management has finally received the feature planned all along – it only took me few years to finally figure it out.
