3 Great Solar Automations in Home Assistant

Three Home Assistant automations to make your inverter happy
- Only Switch Pool on when the forecast predicts lots of power
- Switch off heavy loads when grid disconnects
- Change light bulb colour to red when grid disconnects and to white when reconnected

Thanks for another great video. Must say loving these videos and helping a ton.

[@SolarIntegrations]

Thanks Vaughan, I am glad that they are helping you

[@vaughanza]

@SolarIntegrations Could you do a video that explains what most of the sensors are on the chart / graphs. Explaining the charts will be great thanks

[@JohnBrinkman]

Hi @@vaughanza I will be doing my best to cover this topic in my next video with is for a new dashboard.

[@vaughanza]

@@JohnBrinkman Thanks

Thank you again for the valuable video , i slightly modified the automation by changing the light to flash red on grid power loss and then when power is returned it goes green for a minute before going into normal white mode , you can also make home assistant read out a alert on a something like a google home mini that Loadshedding is in progress and then again read out a another alert that loadshedding has stopped via the TTS engine.

[@mc_allstar4860]

Hi I currently do that using the alexa integration, I'm sure there is a google one too. It will announce loadshedding start in 55 mins and 15 mins warning and then actually when load shedding starts. I can share my code but I'm not sure what the process is for sharing code in the comments.

[@SolarIntegrations]

That's a great suggestion Adrian, thanks for the comments

Sounds great, you are welcome to post the Yaml in your reply :-)

@@SolarIntegrations ok cool so here is the automation code. You need the google chrome cast integration and tts setup. I ca. try help you with that if you don’t. So I have normal announcements from 6am to 8pm then between 8pm and 6am Alexa whispers the announcements so that it doesn’t wake the house up. Happy to assist you further if need be.

To take it further I also have a notification pop up on my TV’s when they are powered on that shows the load-shedding announcements. All my TV’s have Xiaomi MITV boxes and I installed notifications for android/fire tv

The reason why you didn't saw the prodection for today was more then 30kWh is because it was 5 kwh/hour. Not for 1 day!

[@francozaayman8164]

Thank you for your videos. I found them to be very useful!! Will it be possible for you to make a video on how to configure an automation in home assistant that changes the battery SOC settings on the sunsynk invertor. I can think of two variables that will impact this decision: the solar production (weather) and load shedding. This feature will be great for optimal battery use without running out of battery power during load shedding.

[@SolarIntegrations]

Hi Franco, I have an automation video planned to do that exact thing in the next week or so. Just finishing one off with a new Dashboard video and will get onto it :-)
