Hello @Shagger,
If the Door/Window sensors have an embedded temperature sensor, you won’t be able to delete it or hide it. The controller will always create this child device. You can ask for this feature in our Community Feature and Bug Tracker tool. More information on this tool here.
If the Dorr/Window sensors don’t have an embedded temperature sensor, it may be an integration issue. Please share the model number of the device or report it in our Community Feature and Bug Tracker tool.
Kind regards!
