Home assistant Smart Grid input automation

[RodEzIO]

Hello,

Does anyone has an automation example to share for integrating smart grid feature by using home assistant?

I am looking for something that starts the SG mode when the PV production is above X kw.

Thanks

@andreapier, @maps2002, @colseven could possibly help. I don't have PV production.

Hello, I have Solaredge/Home Assistant and I exceed my hot water target value from 48°C to 54°C with a pv excess.

Hi @RodEzIO ,

I am using a similar automation as @colseven , only based on the current solar power production. I am not able to read any values from my heat pump model, so also cannot "complicate" the automation with any heat pump state values :)

thanks you guys, your answer confirmed me that this is the simplest way of doing it. Indeed, I found something similar here https://javiermugueta.blog/2022/02/02/energy-export-management-on-a-solar-pv-system-with-batteries-by-using-home-assistant-automations-electric-heaters-and-smart-switches/

I have designed a custom PCB with 5V relay, clamp diode on serial pin and socket for esp32devkitC. Here is the picture

I guess this one can be closed now.
