# Electricity Price Ticker – Version Information
|
||
|
||
## Current firmware
|
||
|
||
- **Version:** 6.1.2
|
||
- **Release date:** 2026-03-11
|
||
- **Target MCU:** Seeed XIAO ESP32‑C3
|
||
- **Display:** 20x4 I²C LCD (PCF8574, default address `0x27`)
|
||
- **API endpoint:** `https://api.energy-charts.info/price?bzn=SI`
|
||

|
||
|
||
## Highlights of v6.1.2
|
||
|
||
- Fix: restore proper white LED price indicator behavior on ESP32 by avoiding mixing PWM (`analogWrite`) and `digitalWrite` on the same pin.
|
||
- Fix: LED is now truly off when backlight/LED gating turns it off (no more “dim glow”).
|
||
- Change: `updateLeds()` uses PWM only (`analogWrite(pin, 0/255)`) for off/on and blink toggles.
