I have had Tempest hub 1579 up an running for a year. I also have a WF Air from previous device that I would like to add as an indoor tempature and humidity sensor. I can’t seem to connect the WF Air to the Tempest Hub. I am using my iPhone to run the Tempest app. The LED on the hub turns blue when I run the app. I click on Settings, Stations, Select my station, click on Manage Devices, then click on the plus sign at the upper right corner. I place the batteries in the Air and close the cover. The green LED flashes 10 times, then glows steady for about 5 seconds. The LED on the hub flashes blue/cyan, but the Air is never “found”. Am I doing someting wrong, or is the WF Air not compatible with the Tempest Hub?
