Ikea Smart Bulb range?

Hello,

Has anyone had issues with the Ikea Tradfri smart bulbs range from the Smartthings hub?
They work in the same room as the hub, but as soon as I move them to another room they wont turn on or off from the smartthings app

Thanks

Do you have any other directly connected zigbee bulbs that do work in that location?

What’s the architecture like? Adobe or cement walls block a lot more signal than wood, but plaster walls with wire lathing inside can be even worse.

Is there a Wi-Fi extender in the room where the bulbs are?

Have you looked at your Wi-Fi channel versus your zigbee channel? ( this is more important if you don’t have other zigbee devices that are working OK)
