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
