Ikea Tradfri motion sensor with light strips

I’m running HA and Homebridge, and my lights are all ikea tradfri. Now I want to add led strips activated by a motion sensor, but ikea has not strips and i don’t want to buy another gateway.
There are strips compatible with tradfri system or some hack? Do you think using sonoff and tradfri motion sensor could work fine?
