Pylon-Monitor Lite

Brand: Pylon-Monitor
SKU: PM-V2L
Price: 49.00 EUR
Availability: InStock

The same monitoring.
No screen. €49.

Pylon-Monitor Lite runs the exact same firmware as Pylon-Monitor V2 — State of Charge, voltage, cell health, temperatures, JSON API, MQTT and Home Assistant, all identical. The only thing missing is the physical screen: everything you'd read on it lives on a web dashboard instead, open on your phone, tablet or PC at http://pylon-monitor.local. If you always check your battery from a device you're already holding, this is €10 you don't need to spend.

Live in under 2 minutes — captive portal, zero apps

Home Assistant ready — MQTT auto-discovery or REST, zero YAML

Up to 16 batteries chained — mixed Pylontech models supported

Plug & play: 1 RJ45 + 1 USB-C cable, both included

Lifetime firmware updates, free and automatic

Quick start guide

Everything else? Identical.

Same firmware, same PCB family, same firmware update channel as Pylon-Monitor V2 — the enclosure and the screen are the only things this model doesn't have.

WEB

Beautiful web dashboard

Open http://pylon-monitor.local from any phone or PC on your WiFi. This is where the Lite's "screen" really lives.

Home Assistant, done right

Zero-YAML MQTT auto-discovery — 10 sensors appear automatically. Prefer REST? A clean JSON API at /api.json gives you a short, auto-generated YAML paste instead.

WiFi

Plug & Play WiFi setup

On first boot the box creates its own WiFi network. Connect, pick yours, type the password — done.

OTA

Over-the-air updates

New features arrive through a friendly web update page. No cables, no soldering, no skills required.

LAN

100% local, 100% yours

Your battery data stays on your network by default — no telemetry, no subscription. The free Cloud, to see it from anywhere, is optional.

ALM

Configurable alarms

Set your own SOC and temperature thresholds and get a push notification via Pushover the moment either is crossed.

Your cells, back in line. Measured, guided, proven.

A Pylontech pack that rarely reaches 100 % slowly drifts apart — and a pack is only as good as its weakest cell. Smart Balance watches every full charge, scores your balance, names the cell that lags and, when it is due, runs a guided two-hour session with your own inverter. Then it shows you the result, cell by cell.

01MeasureEvery full-charge window, automatically.

02ScoreA balance score out of 100, the weak cell named.

03BalanceOne click: the exact setting for your inverter, a 2-hour hold that starts by itself.

04ProveA before/after report by e-mail, cell by cell.

Lite — frequently asked

Can I add a screen to the Lite later?

No — the enclosure has no display, no cutout and no mounting point for one. If there's any chance you'll want to glance at the box itself later, get Pylon-Monitor V2 instead; the firmware and every feature besides the screen are identical either way.

Is the firmware really the same as Pylon-Monitor V2?

Yes, exactly the same feature set — WiFi setup, web dashboard, JSON API, MQTT/Home Assistant, alarms, OTA updates, multi-battery and high-voltage support. The only code that's different is the part that would draw to a screen this model doesn't have.

How do I check my battery without a screen?

Open http://pylon-monitor.local (or the device's IP address) in any browser on your network — phone, tablet or PC. It's the same live dashboard a Pylon-Monitor V2 owner sees, just not also mirrored onto a physical screen.

Does it support the same batteries, and up to 16 chained?

Yes — identical hardware support: the low-voltage US series (US5000, US3000, US2000, UP2500, Force-L1) and high-voltage Force H2 / H48050 towers, up to 16 batteries chained together.

Which one should I actually buy?

If you want to glance at the box itself for a quick reading with no phone in hand, get Pylon-Monitor V2. If checking your phone, PC or Home Assistant is no trouble at all, the Lite gives you the exact same monitoring for €10 less.
