PVbrain 2 - Project Presentation! {ESPHome} - Control and Management of a Solar Installation
PVbrain2 is an open-source/open-hardware project based on ESPHome (ESP32-S3) for monitoring and controlling a solar installation locally (without relying on the cloud).
Inverters (Voltronic, PIP, WKS, Sofar, Growatt, Victron, etc.), BMS (JK, Daly, Pylontech, etc.), relays, ATS, Linky teleinfo, sensors… the goal is to centralize and automate everything cleanly within Home Assistant.
⚠️ Important:
PVbrain2 is NOT a product for sale. We don't sell anything.
If you're interested in the project, you order your PCBs/components yourself (often through group orders), and the community provides support on Discord.
➡️ This video is the first in a PVbrain2 series: we'll lay the groundwork and cover the hardware, modules, and code structure.
