Arh. They catch other signals. No, not during configuration modes. Sometimes they catch motion sensors, sometimes door sensors. Sometimes THEY catch signals from same devices of our neighbors. It requires to clear their memory and configure them again or they continue switching. I dont have any good explanation to this. Maybe voltage spikes cause remembering mode? Nah. This should not be happening with good product.
The package is not arrived on my adres, seller is quickly communication and money full refund - seller is dependable. I recommend this seller.
