Ikea has recentely released a new series of smart lighting products called Trådfri. The devices currently include light bulbs/panels, remote controls and a motion sensor, but more are promised to be available in the near future. The product line is Zigbee based but also include a cheap gateway product that will let you control everything from an app or other external devices.

Any hope of getting support for this gateway into Girder? I see that other home automation products like Home-Assistant already have decoded the gateway protocol and implemented support for it.
