Havells
Havells Smart Wi-Fi 4-Node Retrofit Module for Existing Switchboards

Full details →Who the Philips Hue White & Color Ambiance Smart Bulb E27 9W is for
Buy it if: Anyone who wants very low dimming, accurate colour, and automations that survive an internet outage.
Avoid it if: Anyone whose fittings are B22 bayonet, and anyone unwilling to add a Rs8,000 Bridge to get the full feature set.
Who the Havells Smart Wi-Fi 4-Node Retrofit Module for Existing Switchboards is for
Buy it if: Anyone with a modern switchboard that has a neutral wire and four circuits worth automating at once.
Avoid it if: Anyone in an older building with no neutral at the switch -- a no-neutral Zigbee module is the alternative.
