It doesn't need it, its just that chips that can run doom are the dirt cheap bottom tier chips now. Rather than making some custom chip only just powerful enough to run the lamp software. You may as well just stick a generic one in.
These IKEA smart bulbs cost about $9 so yes, it is cost effective.
- marcan_42 5y agoChips that can run Doom are nowhere near the dirt cheap bottom tier. The dirt cheap bottom tier is this $.03 chip: https://hackaday.com/2019/04/26/making-a-three-cent-microcontroller-useful/ https://hackaday.com/2019/04/26/making-a-three-cent-microcon... Chips that can run Doom, though, are just about at the low end for internet-connected devices. You can't run an IoT stack on that $.03 thing. The chip in the bulb is exactly in the right ballpark for the application. You do need a fairly beefy chip to run multiple network protocols efficiently.
- foobar33333 5y agoThere is no network stack on the ikea bulbs. They only support local communication via zigbee. No IP/TCP/etc. Its the gateway device that does wifi/networking.
- marcan_42 5y agoZigBee is a network protocol with a network stack. Just because it isn't TCP/IP does not mean it's not a network. It has addressing, routing and routing tables, fragmentation and reassembly, discovery, error detection, packet retransmission, and everything else you'd expect from a functional network protocol.
