In the last ten years the Earths has been hit with very high radiation from Solar activity. This solar radition (x-rays, gamma-rays, etc...)
can and will cause garage doors to open for no apparent reason.
Solar activity also causes RFI (Radio Freq. Interferance) radio waves all across the spectrum are bouncing everywhere.
If you live in the Northern US/Canada, you may find that you have trouble with any wireless devices when you start seeing the Aurura (Norther Lights)
