Wow, i actually researched about wipro and my own smart plug found out they are almost same just different rebranding.. both are tuya. But how mine developed the stucked power consumption live metrics problem, i dont know. Maybe hardware issue.
I have also tried to check if custom firmware can be installed or not. But unfortunately it is updated to 1.1.17 so it’s not possible to flash custom firmware without opening up this and sholder wires into its flash chip. Which is too much effort for me also i don’t have the equipments.
if the app is good then i will go with tplink because smartlife app feels like it made by caveman who recently discovered fire..
I have Aziot 10A version and I believe wattage measurement will be off by a lot as it consistently shows very high voltage (above 250V) in my house. So not the most accurate.
i haven’t checked for accuracy but they have been working for long time and never failed. i mainly use it to remote switch on and off devices and run them on timer thats all.
If you want real accuracy compare these wifi plugs against an actual electricity meter, those have class standard and are temperature compensated. So you get exactly what is advertised.
These define how precise the meter is, expressed as a percentage error under standard test conditions. Common accuracy classes:
Class 0.2S → Very high precision (±0.2%) → often used for laboratory or revenue-grade applications.
Class 0.5S → High precision (±0.5%) → utility billing for large consumers.
Class 1.0 → Standard precision (±1.0%) → typical for residential & commercial billing.
Class 2.0 → Lower precision (±2.0%) → older meters, sub-metering, or less critical applications.
(The “S” means the meter is suitable for wider operating ranges, especially at low loads.)
The best way to test would be to wire them series and connect the load for long period of time, the small errors will accumulate giving you the perfect comparison results between real power meter vs wifi power meter.
