Gateways

WIFI UDP/IP <=> Serial link

Running on ESP8266 with a WIFI connection converts serial link frames on UDP frames and vis et versa

Ethernet UDP/IP <=> RF433 home made protocol

Running on Arduino with a Ethernet connection converts RF433 frames on UDP frames and vis et versa

Ethernet UDP/IP <=> RF433 HomeEasy and Somfy protocol

Running on Arduino with a Ethernet connection converts UDP instruction on RF433/Homeeasy frame or RF Somfy protocol
