Hello,
I am evaluating to buy the cheap alarm system based on Sonoff RF Bridge 433 MHz.
I have two basic and main I cannot answer by myself.
RF Siren
Is there any RF siren certified by Itead or tested by anyone actually working with RF Bridge ?
Can I use the siren to bè turned on based on paired RF sensors alarms ? How ?
Behaviour without internet connection
Let's say a thief cut home Power.
I can protect Sonoff RF with a battere/UPS.
What does happen when internet connection is Lost ?
Can automated actions on RF devices (like the siren above) still happen without internet connection to the Cloud ?
Thanks !
Emiliano.
