Sorry if this has been covered over and over, but I haven’t had much luck searching. I’d like to buy a tempest sensor only to attach to my existing WF hub. I’d be using it in parallel with my existing Sky and Air devices. I don’t see an option for this in the WF store. How can I buy just the Tempest sensor unit? ---

That will be available soon but you might want to rethink buying the Tempest Sensor array only. The new Tempest Hub has the added ability to update the firmware on the Sensor array. Your current Hub does not allow this. ---

Ah, interesting. Are there any compatibility issues between the new hub and the old SKY/AIR? ---

no, the newer hub can serve old and new devices
