+ * F&F LE-01MR - This is a single phase energy meter with rs485 modbus interface 
+ *               (and bidirectional energy counting - enabled by RS485).
+ * It measure: Active energy imported AE+ [kWh] , Reactive energy imported RE+ [kvarh],
+ *             Voltage V [V], Current I [A], Frequency F [Hz], power factor (aka "cos-phi"),
+ *             Active power P [kW], Reactive power Q [kVAr], Apparent power S [kVA],
+ *             *Active energy exported AE- [kWh] (when meter is switched to bi-directional counting then 
+ *                  reactive energy imported register contains value of Active energy exported).
+ *
+ * Meter descriptions at manufacturer page (english version have some description errors):
+ *    EN: https://www.fif.com.pl/en/usage-electric-power-meters/517-electricity-consumption-meter-le-01mr.html
+ *    PL: https://www.fif.com.pl/pl/liczniki-zuzycia-energii-elektrycznej/517-licznik-zuzycia-energii-le-01mr.html
+ * 
+ * Note about communication settings: The meter must be reconfigured to use baudrate 2400 (or 9600) *without* 
+ *                                    parity bit - by default the meter is configured to 9600 8E1 
+ *                                    (Frame format: "EVEN 1") . To make those changes, use LE-Config 
+ *                                    software (can be found in download tab in product page - link above)
+ *                                    and USB-RS485 dongle (those cheap ~2$ from ali works fine)
