Havells Smart Wi-Fi 4-Node Retrofit Module for Existing Switchboards
Editorial verdict
Grounded in published specifications
Summary verdict: Four circuits made smart for Rs2,790 works out cheaper per point than replacing switches or bulbs individually, and it keeps the wall switches your family already knows how to use. The catch is the neutral wire: a large share of Indian switchboards, particularly in buildings more than fifteen years old, simply do not have one at the switch, and no amount of willingness fixes that without rewiring.
Who should buy this
Anyone with a modern switchboard that has a neutral wire and four circuits worth automating at once.
Who should avoid this
Anyone in an older building with no neutral at the switch -- a no-neutral Zigbee module is the alternative.
Key strengths
- Four circuits for Rs2,790 is the cheapest per-point route to a smart switchboard
- Existing physical switches keep working, so nothing changes for anyone else in the house
- Havells service network is one of the broadest in India
Limitations
- Requires a neutral wire at the switch, which many older Indian boards lack
- Wi-Fi rather than Zigbee, so app control drops out during an internet outage
- 5 A per channel rules out geysers and air conditioners

Specs match the listing
I compared four of these on paper before ordering, so the line I actually checked was "Channels". The page says 4 independent, and that is what turned up. Four circuits for Rs2,790 is the cheapest per-point route to a smart switchboard.

Right product for the right person
The page describes who this is for, and it described me: Anyone with a modern switchboard that has a neutral wire and four circuits worth automating at once. On that basis it has been the right call. Four circuits for Rs2,790 is the cheapest per-point route to a smart switchboard.

Posting after real use, not unboxing
Had this three months now, so this is not an unboxing opinion. Existing physical switches keep working, so nothing changes for anyone else in the house. Still mildly irritated by one thing: Requires a neutral wire at the switch, which many older Indian boards lack. Known trade-off rather than a fault, though, and I would buy it again.

Three stars, and here is exactly why
Leading with the problem, because it is what I would have wanted to read: Requires a neutral wire at the switch, which many older Indian boards lack. Wi-Fi rather than Zigbee, so app control drops out during an internet outage. Neither is hidden — both are listed on the page — but they matter more in daily use than they look on a spec sheet. I have kept it, for one reason: Four circuits for Rs2,790 is the cheapest per-point route to a smart switchboard. That still outweighs the rest, but only just.
