We have a 5 in 1 weather station and 2 remote temp and humidity sensors we use on different floors in the house. When we had our first hub fail after an upgrade a curie sent a replacement. Since we received the new smart hub another remote sensor has appeared on on the acurite app. We can't find this new sensor and the temp an humidity reported by the unknown sensor does not match any readings from other devices we have . How can can we find out what this device is.
