You instead need to throw most the board of directors of the insurance provider and device manufacturer in question into a Faraday cage, lock it, and walk away.

On a more serious note, this is a new world of crazy for me I wasn't aware of. I wonder how difficult it would be to push forged data back to the monitoring agency with physical access to the machine with an independent setup. Then, simply put your actual device in a Faraday cage so you can still use your device as needed, with insurance covering it, without insurance invading your privacy and likely using that data for other unscrupulous purposes as well.
