Thank you very much for great explanation!!!

But is there a way how to connect ESP8266 to Controller. In MySensors are available just ethernet or serial gateway with NRF. Of course I can connect ESP to NRF and then use serial gateway but then there is no difference if I use ESP or nano.

My idea is that I want to use wireless network for sensors. One of my sensor should be LCD/TFT with touch so I wanted to prevent to use NRF (it occuy SPI)

Hello,

Maybe I have a stupid question but I did not find proper information on this forum or internet.

Currently I use serial gateway (Uno + NRF24 connected via USB, MyController) for connection of sensors. So sensors are arduinos (uno, mini, ...) with sensor and NRF24.

And now my stupid question. Can I connect WeMos D1 mini directly to my gateway (without NRF24)? Both items works on 2.4GHz.

Thank you for your reply

Hello,

I would like to promote my home automation system and be able to control room settings for each room.

I use MySensors + MyController.

In rooms I measure Temperature, Humidity, AirQuality, and I control air condition, heating and electronic window blind.

I would like to have a TFT touch display in each room with possibility to see all measured values and (on button click or slide) + be able to control temperature (thermostat), open or close window blind.

Additionally i would like to build it small .. not like on mega but on nano. Unfortunatley NRF and TFT use MISO/MOSI so I need to use custom pins for TFT.

Do you know if it is doable and could you recommend solution/concept?

Thank you very much!
