Edit: At least on amazon.in I could not find any.
Don't ZigBee and zwave smart plugs work locally only?
But with both zigbee/thread the problem is shifted towards the gateway instead so you'll have to do it yourself / pick one tu trust there. But here I think/hope Thread is going to have better interoperability.
And if you don’t want to deal with the hub potentially being your next issue, you can always throw home assistant on a computer / raspberry pi / whatever and control them locally. If you want remote access when you’re off your network, it’s up to you to figure out how to securely get the bits from your phone to your home assistant server.
And that's not really terribly hard. I run a VPN server at home, and connect from my phone through that.
Dunno if they ship to India, but I'm sure you can find similar products on AliExpress if you search for the same keywords
I wish more manufacturers provided this sort of thing!
These come pre-flashed with Tasmota, which can rudimentarily be controlled via an HTTP API, and fully via MQTT.
Here's a list of all Plugs and Sockets which can be flashed with this firmware: https://templates.blakadder.com/plug.html
they also have bulbs too. Got both setup with Home assistant, seems to work fine.
Now I can control the lights from my bed even when the LAN is down.
Here are my rough notes on the project https://github.com/Yossi/Bluetooth_lightswitch
The fact is that the Hue bridge supports connecting to a cloud for control from anywhere, so they'll advertise that since it's what many people are after. But it works perfectly fine offline, and you can manage it via Home Assistant, for example.
Whatever you do, don't buy TP-Link. Those had local control but they removed it due to "security concerns" in an automatic update. And of course promoting their data mining cloud had nothing to do with it.
