Yes that is correct one wsp8266 wired to the magnetic reed switch for the door and a dht22, this can either be mains (5v) or battery.
The other esp8266 hard wired to a lcd or oled and a servo (with a pointer).
I'll look into post #13 and see what i can come up with, I have managed to connect both devices to my network so halfway there.
Thanks for all the help
