Is there an automatic power transfer switch (120v) controlled by an ESP32 device?

I was trying to think if I could put together a diy load shifting setup for my homelab + main PC using a LiFePO4 battery + inverter. Obv there are portable power stations (Anker, EcoFlow, Pecron, etc) that can do this within their apps, but I would prefer not to have an extra app and instead use ESPHome + HomeAssistant for power monitoring and automations for when to use outlet power and when to use the battery.

Maybe a module that could connect to an ESP32 doesn't exist that could reliably switch the power fast enough.

I saw a post from years ago thinking about using an old UPS' insides to make this happen, but I don't see anything come from it.
