That's such a shame. I bought quite a few IKEA devices as they were the cheapest in the market and were Zigbee-driven, which meant I could use it with my custom-made SmartHome software (which does what Home Assistant does but without a heavy runtime) and they connected with other manufacturer's devices (they form a mesh, so as long as you have a Zigbee device every few 10s of meters, the devices can communicate with the central hub even from very far away). I wonder if I will be able to connect to Thread devices at all now.
