I recently bought a second tempest station to place in a different location, 7.8 miles away from the first, connected to a different WiFi network. None of the suggested articles at the tempest help site contemplate such a situation.
Surely this must be possible, but how?
It is possible to do. I set up a second one at my home before obtaining a second hub to operate it. I would call customer service for specific details. Their support number is 1.844.968.3679. I did find this or maybe you ran across it already https://tinyurl.com/5ffpuf2r
My confusion - my problem was w/ Google Password Manager & the fact that I needed to be in two places at once to realize that, which I later did.
