Connenct a RS485 Network to a NodeMCU Gateway?
-
Just some guesses:
The PIN assignment for arduino nano is due to the use of altsoftserial lib.
Most likely you may rather use hardware serial on ESP8266. See http://esp8266.github.io/Arduino/versions/2.3.0/doc/reference.html for the relevant PINs on the ESP (most likely serial0 is the better choice).
Connect DE-RE (linked together) to any interrupt-capable PIN and adopt sketch accordingly.Btw: What is your motivation to build a wired network and then connect the whole thing wirelessly to your controller? (I personally try to get rid of all RF transmissions, so this is why I use RS485 as preferred transport layer and connect the whole thing via USB...)

Hello,
i will build a few Sensors in the yard and i thing the best way to connect these Sensor Array to the Controller is WIFI.

ThomasD@ThomasDr Thx for info.
So using wires to connect also teh GW seems not to be an option. And why do you not plan a entirely wireless infrastructure and - if really needed - a repeater node instead of the NodeMCU for the wireless bridge in the house? Especially: RFM69@868MHz should have better range than wifi. To address security related troubles also signing etc. could be used.
Controller: FHEM; MySensors: 2.3.1, RS485,nRF24,RFM69, serial Gateways
