WiFi Energy Meter Tuya App Control with RS485 power 110-240V, 50/60Hz energy meter luxe meter
energy meter luxe meter
Low Power comsumption, Long Life, High Accuracy
Basic Function
Measuring positive & negative active energy with negative energy accumulated into positive energy
The meter display total active energy, positive active energy , negative active energy , total reactive energy , balance active energy
The meter also display real voltage , real current , real active power , real power factor , real frequency
Pulse LED indicates working of meter,Pulse output with optical coupling isolation .
RS485 communication port and WIFI communication
Measuring active energy without calibration under long term operation
Display step by step with button\
APP can display total active energy, balance active energy, real voltage , current ,active power and remoter control on/off.
Hour/Day/Month/Year history active energy consumption tracking by APP
It has overvoltage and undervoltage protection , it can set value from APP and by button
Each protection function can be opened/closed as customer requirement
It has overload protection ,it can set value from APP
Voice control on/off function
Alarm event records on APP
Prepayment function, if balance energy used up. It will cut off automatic. This function can be opened/closed by APP
Energy data can store on memory chip when power off, it also still measure energy whenlose WIFI connection and it will update the energy on APP when connect WIFI again
It can control on/off by hand with button when prepayment function close
It has timing control function , it can set value from APP
It can reset the active energy to zero from APP

Overvoltage recovery value |
260V+1(default)= (APP overvoltage value - 10V) |
Undervoltage protection value |
170V+1(default),APP can set value |
Undervoltage recovery value |
180V+1(default)= (APP overvoltage value + 10V) |

Pre-paid Function for Landlord and Tenant
This function is for landlord rental house. The tenant purchase the kwh power advance.
When tenant purchased 100KWH, the balance shows 100KWH.
When used 20KWH, balance is 80KWH.
When used 90KWH, balance is 10KWH.
If not top up, the meter shut off the power automatically when the balance is 0KWH.
