That's the whole device.
One small box, one captive portal, one dashboard, one JSON endpoint, one update button. No cloud, no app, no subscription — €29 once.
No marketing fluff. These are the real pages served by your Pylon-Monitor at http://pylon-monitor.local — exactly what you'll see the moment you plug it in. And that moment is under 2 minutes after opening the box.
A crisp 1.8" IPS TFT panel shows the State of Charge in giant digits, with voltage and current beside it and SOH and cycle count below — readable across the room, no phone required.
No fan, no buttons to fiddle with — just glance at the box.
On first power-on, the Pylon-Monitor creates its own network PylonMonitor-Setup. Connect from any phone, the setup page opens by itself.
A username/password gate protects the dashboard. Credentials are stored on the device and changed from Settings. Default is admin / admin — change it on first login.
The home screen of the device. Three live cards (Summary, Health & System, Temperatures) and one nav strip to jump anywhere in two clicks.
http://pylon-monitor.local · current IP <DEVICE-IP>configuration.yaml — six sensors appear in HA.Hostname, login, static IP, MQTT broker, REST API helper and Pushover emergency notifications. All in one form, with inline hints that show your current IP and copy-paste-ready YAML.
http://yourname.localDownload the latest .bin, upload it, the device reboots into the new version. No cables, no soldering, no Arduino IDE. Your settings are preserved across updates.
https://pylon-monitor.com/update.bin/api.jsonOne endpoint, all the data. Ready for Home Assistant, Node-RED, Jeedom, Domoticz, openHAB, Grafana, InfluxDB or any cron-driven script.
Two safety buttons in the navigation strip. Reboot triggers a confirmation then restarts the device cleanly. Factory Reset wipes WiFi credentials, MQTT and login — reopening the captive portal so you can start fresh.
This action is irreversible. It will erase your saved WiFi networks, MQTT configuration and Security settings.
