hi guys! sorry for my english..I want to make a simple alert system using Sonoff RF Bridge 433 + PIR2 PIR Sensor and Android phone ...
this system is designed to work with the internet and that ewelink application put on the phone ... I wish I could connect that sonoff rf bridge 433 directly via wifi with the phone and when the sensor is triggered I get the notification directly on the phone without being need internet ... some kind of local network or i don't know how to tell them ... i also have an arduino one, can you help me with something? thanks a lot
You need a way to connect to your phone - such as a Bluetooth or WiFi adapter.
If you go the WiFi route, consider dropping the Arduino and replacing it with a WeMOS or NodeMCU board, with the ESP8266 processor.
.. first of all thanks for the help .. then i will have to connect sonoff 433 to modull and on the phone i look for it as a router ... the problem is how will i get a notification when the pir sensor is activated? will the basic application work? "it does not depend on the cloud and the internet connection? if I could activate that buzzer included in the sonoff board to emit a warning sound when the sensor is activated so that I could get out of any connection and also no phone ...
You can connect your phone to an ESP8266 in access point mode without connecting to the Internet, even without the need of a router.
No experience with the sonoff as such, nor "the basic application" whatever that may be.
ok..I connect with the phone to ESP8266 and with Sonoff ... when the pir sensor detects movement and transmits Sonoff and it will turn the signal into wifi ... how I will receive a notification on the phone? ...
the initial system is: PIR sensor detects movement and transmits it Sonoff RF Bridge 433, it converts the received signal into wifi and transmits it to a router and I through the internet connection and the ewelink application receive a notification ...
silviuralu:
how I will receive a notification on the phone? ...
Some kind of phone app that can receive this signal - but that is well outside the scope of this forum.
ok..thank you very much!
