@foad62 I don't know if it helps but you can modify the default pins MySensors expects the NRF chip to be connected to. Here is an example, works on my Nano with MySensors 2.0:

#define MY_RADIO_NRF24
#define MY_SOFTSPI
#define MY_RF24_CE_PIN 11
#define MY_RF24_CS_PIN 6
#define MY_SOFT_SPI_SCK_PIN 10
#define MY_SOFT_SPI_MISO_PIN 9
#define MY_SOFT_SPI_MOSI_PIN 7

#include <SPI.h>
#include <MySensors.h>

In my case I didn't try connecting another SPI device, I just moved the pins for easier NRF soldering on a perfboard.

Hi all,
This post is great. I started writing a similar library myself for Electra AC, I might just add it on top of @ToniA's library.

Quick question: can anyone recommend MySensors compatible controller that supports temperature/fan commands ?
The only thing I came across so far is this modification for Vera UI7 thermostat: https://forum.mysensors.org/topic/3606/redesigned-vera-ui7-thermostat-with-heat-cool-setpoint-hvac-state-fan-status-energy-mode

Thanks!

Hi all
I'm looking for a controller that allows controlling HVAC and showing/responding to soil moisture levels.

For HVAC, I have Arduino device capable of sending the right IR codes for my HVAC.
I'd like the controller to have an interface allowing me to power on/off, set mode (heat/cool/dehumid/...), control fan speed, target temperature, flaps, sleep mode, ionizer.

For soil moisture level, simple reading should suffice, however it should support multiple moist sensors connected to a single Arduino device.

Any suggestions for most suitable controller ? ideally with built-in user interface that supports the level of HVAC control I want out of the box

Thanks!
