- Sun Jul 17, 2016 9:31 pm #50937 I just purchased 2 Adafruit Huzzah ESP-12 modules. I would like to build an actual weather station with wind speed, direction, temp, humidity and barometric pressure and whatever else I can add. I would like to use one ESP-12 as the outside "brain" for all the sensors and use the 2nd one to receive that data and display it on a Nextion 5" TFT display along with temp and humidity of indoor sensors and a RTC module.
Yea I could go out and buy a weather station and throw it up on the roof and be done with it but what fun is that? This is for my own personal use, not a school project that needs to be done in a week. If anyone could give me some pointers to get started as I have Googled a million sites for ESP weather stations and most of them are an ESP on a proto board with a DHT11/22 connected.
So in your honest opinion is this overkill using 2 ESP's communicating this way. If so then I can try the NRF24's or the 05/06 Bluetooth modules. Thanks for any input on this project!!

IF your outdoor unit will be batery operated, you would like to use sth more low power than wifi.
If on the other hand you are planning to run a cable to your outdoor unit, think about using a spare wire for communication; nothing more reliable than copper.
There is a range of fine sensors for all kinds of enviromental purposes:
temperature, humidity, pressure, UV, air-purity, wind direction/speed, percipitation ...
most of them as easy to implement as buying the pure sensor element and linking the correct library, some of them more challenging to your diy as wind speed/direction or percipitation. But still there is the option to buy these as finished module.
just have fun picking bits and pieces from others projects and conjuring up your ultimate weather station by only combinig what you see fit and/or worthy...

for powering, ill go solar powered.

So how will I set up the board with all the sensors ? Will it be the server or workstation or other? I have seen sketches where two 8266's talk but never set up a pair and made it work. I will also need to work on the "sleep" mode as I don't need readings every second.
If anyone has found a basic two 8266 communication setup that works please pass it along as a starting place. Thanks
