Installation guide

True plug & play. From unboxing to live dashboard in under 2 minutes. One RJ45 cable, one USB cable, one captive portal — if you can plug in a phone charger, you can install a Pylon-Monitor.

What's in the box

You will also need: a 5V USB power source (any phone charger, a free port on your inverter, a power bank…). The device draws under 0.5 W.

Step-by-step

  1. Plug into the battery

    Connect one end of the RJ45 cable into the Console port of your Pylontech battery (top of the master battery in a stack). Plug the other end into the RJ45 socket on the Pylon-Monitor.

  2. Power the device

    Plug the micro-USB cable into the Pylon-Monitor and into any 5V USB source. The TFT screen lights up within a couple of seconds.

  3. Connect to the setup WiFi

    On your phone or laptop, open WiFi settings. A new network called PylonMonitor-Setup appears. Connect to it (no password). A captive portal opens automatically; if not, browse to http://192.168.4.1.

  4. Pick your home WiFi

    The portal shows a list of nearby networks. Tap yours, enter the password, hit Save. The Pylon-Monitor reboots and joins your network.

  5. Open the dashboard

    After reboot, the TFT screen shows the device's IP address (the one your router assigned). Type it into your browser, or try http://pylon-monitor.local if your network supports mDNS. You'll see the live dashboard.

That's it. Bookmark the dashboard on your phone's home screen for one-tap access.

Once connected to the battery, the TFT screen shows:

While booting it briefly shows the IP address — note it down to access the dashboard.

Troubleshooting

The TFT screen stays blank

Check the USB cable and power source. Try a different USB port. The device draws very little, but it does need a proper 5V supply.

"No battery data" on the TFT screen

The RJ45 cable is plugged into the wrong port. Pylontech batteries have several RJ45 sockets — make sure you're using the one labeled Console, not RS485, CAN or Link.

I don't see PylonMonitor-Setup

The device may have already joined a previous network. Hold the reset button for 5 seconds, or use the Factory Reset button in the web dashboard if you still have access to it.

pylon-monitor.local doesn't open

mDNS may be disabled on your network. Just use the IP address shown on the TFT screen instead.
