And it shows the power consumption too (irrespective of accuracy, it does put some data forth). Can get a 6A to 16A adapter too. 6A plugs works on the plug already.

And way more, it has notifications for power monitoring! It can turn off the socket if power exceeds a threshold or falls below a threshold. Newest firmware update has a "charge guard" feature that turns off the socket when your phone switches to slow charging (above 70/80%) — useful if you're of the mindset that batteries shouldn't be charged above 80% for longer life.
are they better than wipro ones ? I have currently 8 plugs from wipro need 2 more so thinking of getting tplink one now
You will have to install tp link app to control those plugs as they are not compatible with tuya/smartlife app.
How accurate are these. Better than these wipro and other tuya/smartlife based wrt features and accuracy?

I haven't used any of the app based plugs. For the Polycab ones, I flashed Tasmota without ever setting them up.
These TP-Link Tapo ones are just as accurate as the calibrated Tasmota ones.
It's very impressive, I tested it just now at a small load and at a >1kW load:

Not sure but the simplest solution would be to use some power/voltage tester to compare the readings of any typical load device with smart app readings & find the deviation percentage & then just use that to calculate correct readings from smart app readings. In my case I got a supposedly more accurate power plug which showed me that wipro smart plugs have a deviation of as much as around +30% so now I simply multiply wipro smart plug power consumption readings by 0.7 to get an estimate of supposedly accurate readings.

I have the Tapo P110, did not know it was so accurate
My non-inverter ac has a rated capacity of 1618W but Tapo always showed 1300-1400W so I was doubtful about it's accuracy

Yes, that's the one.
I haven't set up HA yet, just going by MQTT/Node-RED automations.
With ACs, I see a variance of a few hundred watts depending on whether the air filters are clean or not.

I've been getting the Tapo P110 smart plugs for all new requirements, even with the stock firmware, I liked the Tapo app better than Tuya/SmartLife. It seems more polished.
Only gripe is the lack of a 6A/10A model so cannot use it with non-16A sockets unless I use an adapter, and I am not a big fan of such adapters. To start with it makes the whole thing pretty bulky.
The actual usage is mostly less than the rated capacity, I've noticed that with my non-inverter AC too. Regarding the stabiliser, yes, need to keep it turned off. I'd have expected such devices to be more power efficient when idle. My V-Guard stabiliser seem to consume around 10W with no load.

This feature is damn good afait and i guess it should be fairly easy if wipro wants can be put in there features list too.

If you have home assistant, you can create an automation to do any of this and more. The wipro plugs can be used out of the box with the localtuya integration. I did that because I was too lazy to open them up and reflash them with esphome/tasmota/etc. You also get the ability to poll them for power data much more often than the wirpo/tuyasmart app does.
time based routines will work only if it has internet access whereas my old smart plugs which I got from Aliexpress works fine without internet. The old plugs needed internet only for setup.I'm talking about only the timer function like turn off at and turn on at certain time. This specific use-case is working fine on Tp-link one and old plugs from Frankever... Fact is that, i enable 2.4Ghz network only for activating these smart plugs and after that i disable, run only 5Ghz network in my home. Except the amazon one, everything is working fine as timed(Frankever plugs are working for more than three years). This particular socket is small socket, not the 16A big socket, otherwise i should have gone for TP-link model once again.

Sorry, not filters. I meant the contactor. This is an electromagnetic switch/relay inside the outdoor unit, it's responsible for turning on the compressor in non-inverter units.
Over time, it attracts lead/iron particles in the air which form a layer of metallic dust over its contacts, increasing the resistance and also power consumption.
These contactors have small plastic dust covers that are removed and discarded by AC technicans during installation/servicing — this is done so it would fail prematurely and you'd call them to come back and fix it a few months later.
The dust covers help a little but you'll still need to clean the contactor regularly since our air has a significant amount of ferrous materials that find its way inside.
I change mine every year or so, or whenever I notice that the power consumption has creeped up by a couple of amps.
I've been meaning to make a post about this, I'll see if mine needs changing/cleaning in a day or five and take a few photos to explain what needs to be done.
