The Pylon-Monitor V2 is a standalone device that reads State of Charge, voltage, current, cell health (SOH) and temperatures from your Pylontech battery in real time, straight from the Console (RJ45) port. All data is exposed through a clean JSON API and a web dashboard reachable over WiFi from any phone, tablet or PC — no USB cable permanently tethered to a computer.
Truly plug & play: under 2 minutes from unboxing to a live dashboard, no app, no account, no cloud.
