The latter is overengineering for safety, using a fast chip isn't. But I imagine it's the cheapest, small SoC that offers bluetooth or wifi, or whatever a "smart" lamp needs. If someone wants to rail against the need for smart lamps, however, they'd have a point.
- wyager 4y agoIkea uses zigbee. Better for this purpose than wifi or BT (but sadly not much).
- Comevius 4y agoA Cortex-M33 microcontroller costs like a coffee, and much less that that for Ikea that can then sell more lamps and at a higher margin, because people like introducing more complications in their lives, like software updates for what used to be a wire and a switch.
