If you can plug in a phone charger, you can install it. Two cables, your WiFi, and your battery appears on your phone — in about two minutes, with no tools and no app.

Both cables are included. Net weight ~93 g.
Plug one end of the RJ45 cable into the port labelled Console on your Pylontech (the master battery if you have several), and the other end into the Pylon-Monitor. It clicks in — that's the hardest part.

Plug the USB cable into the Pylon-Monitor and into any 5 V USB source. It starts in a couple of seconds (the V2's screen lights up).
On your phone, open WiFi settings and connect to PylonMonitor-Setup (no password). A setup page opens by itself; if not, go to http://192.168.4.1.
Tap your network in the list, type its password and press Save and connect. The Pylon-Monitor restarts and joins your WiFi.
Type http://pylon-monitor.local in your browser — or the IP address shown at the bottom of the V2's screen. Your battery is live: charge, power, health, every cell. The first time, it asks you to create your own password (there is no default password).
No configuration file, nothing to touch on your inverter. Here's what you can do next, whenever you like:
hostname.localEvery element except the percentage can be switched on or off from the dashboard's Screen Display page, with a live preview. The Lite has no screen: you read everything on your phone.
Check the USB cable and the power source, and try another USB port or charger. The device draws very little, but it needs a proper 5 V supply.
The RJ45 cable is in the wrong port. Pylontech batteries have several RJ45 sockets: use the one labelled Console, not RS485, CAN or Link.
Almost always the link cable between batteries: it must leave LINK PORT 1 on the master and land in LINK PORT 0 on the first slave — never the other way round, never 0 to 0. Each further battery repeats 1 → 0. See the wiring photo.
The device may already have joined a previous network. Press the reset button (back of the enclosure) twice quickly to reopen the setup network — nothing is erased.
Your network may not support it (mDNS). Use the IP address shown on the V2's screen, or find it in your router's list of connected devices.
Do the setup within about 5 m of the router, make sure a 2.4 GHz network is available (avoid "WPA3 only"), and retype the password carefully.
Use Reset via USB: it reinstalls the device from Chrome or Edge with a USB cable, in a few minutes.
It's on the back of the enclosure. Each press is short — nothing to hold down. What counts is 2 or 3 quick presses in a row (each within 8 seconds of the last).

Pylon-Monitor tells Home Assistant when the battery fills up and when it runs low. Four simple rules, and the washing machine, the water heater and the car use your sun instead of the grid. Watch a day:
Your solar production
Your consumption
Automations
Logbook
Simulation of a sunny day for a house with 5 kWp of panels, a 10 kWh battery, a car that needs 10 kWh and a water heater. The energy delivered to each appliance is the same in both scenarios; only the timing changes. Your figures depend on your system, your tariff and the weather.
