Thank you. The box is ready. Next step connect all hardware. So far no luck with the display (KMR-1.8 SPI). What kind of display model you used in this project.

petewill

@lis610 This is the display I used.

Got the same display. It is working with Adafruit graphicstest example. I did not connect any components just display. If I ran the FAN sketch should be something showing on the display?
Or need to connect everything?

petewill

@lis610 is #define TFT_DISPLAY_ON uncommented? Also, you will at least need the radio attached so the MySensors code can fully load (you can also setup defines to proceed without connecting to gateway but I don't remember them off the top of my head). I don't remember if there are any other dependencies since it as been so long since I built this.

Please help
Display is working with Adafruit graphicstest example pins:
#define TFT_CS 10 #define TFT_RST 9 #define TFT_DC 8# define TFT_SCLK 13 #define TFT_MOSI 11
I did try the same pins in FAN sketch -nothing on display
Tryed pin# from FAN sketch on Adafruit graphicstest- nothing on display.
Nothing come up
I did connect to the radio. Got something from MY_DUBUG not sure is it good or bad:

@lis610 It looks like it's having issues communicating with your gateway. Here is a link to the log parser. You can use this in the future to check out your logs.

Also, did you comment/uncomment the proper defines as noted above and in the code comments?

Try adding this line before #include <MySensors.h>

#define MY_TRANSPORT_WAIT_READY_MS 4000 //This will allow the sensor to function if it can't find the gateway when it first starts up

Hi Pete,
Do you see anything wrong with gateway, node and vera

petewill

@lis610 sorry, I'm not a place where I can look in depth. It looks like your code isn't communicating with the gateway though. Did you try the line of code above? The device should work with the push button even if it can't communicate with the gateway (with that code).

lis610

I will come back to the communication issue later.
In your resent code SPI is comment out " //#include <SPI.h> " what is the reason you comment SPI?
The display is not showing anything even with: #define TFT_DISPLAY_ON. and #include <SPI.h>

petewill

@lis610 if it can't communicate with the gateway and controller the node will never get to the loop which could be why the display isn't working. The SPI include used to be required for MySensors.

hard-shovel

@lis610 It seems you have two problems.
1 The radio is not connecting reliably with the gateway and may blocking the display from starting.
There are lots of other messages on troubleshooting radio problems.

2 The Graphic Display is not operating correctly.

For Item one, You eventually need to resolve the radio problem, However as pete stated in his message if you add the following define it will allow the sketch to run, I can confirm this as i have just tested with just a arduino and just a graphics display.

#define MY_TRANSPORT_WAIT_READY_MS 4000 //This will allow the sensor to function if it can't find the gateway when it first starts up

So if you add this and the display still does not display then you need to test the display connections.

You stated

"Display is working with Adafruit graphicstest example pins:
#define TFT_CS 10 #define TFT_RST 9 #define TFT_DC 8# define TFT_SCLK 13 #define TFT_MOSI 11
I did try the same pins in FAN sketch -nothing on display
Tryed pin# from FAN sketch on Adafruit graphicstest- nothing on display."

So with standard connections the display is working.
So you need to test and get the display working with the adafruit test program using the correct pins required for the house fan program.

Add the following info the adafruit test sketch as option 3 and comment out the options 1 and 2. Wire the graphic display as per the house fan requirements and it should work.

// Option 3: testing pins used in Whole House Fan Node
#define TFT_CS     3
#define TFT_DC     6
#define TFT_MOSI   7
#define TFT_SCLK   8
#define TFT_RST    0  // you can also connect this to the Arduino reset
                      // in which case, set this #define pin to 0

Adafruit_ST7735 tft = Adafruit_ST7735(TFT_CS, TFT_DC, TFT_MOSI, TFT_SCLK, TFT_RST);

If it does not work the same as when connected to the standard connections , then your wiring is in error and need to be changed to make it work before proceeding to the other sketch.

lis610

Thank you very much. Star Over. Rewire display and change the code. Never thought I would be excited to see the word ”Error” on display :).
I got five NRF24L01+. Two of them are not working at all. Looks like the one on the gateway working ok, but the node is unstable.
Do I need to create an additional device for Fan in Vera or, it will be displayed within the MySensors serial gateway?

petewill

@hard-shovel Thanks for the help.

@lis610 You are picking a very advanced project to start with. If you have the time I'd suggest an easier project like a motion sensor to get started. If you want to keep going I'd suggest doing some additional reading/watching on how this all works. Not trying to be critical but rather save you frustration.

I'm not running UI7 on my Vera so I haven't tested but it should automatically create your device as long as you are including it when first starting the node. For me I press the "Start" button then power up my node (the fan in this case).

However, if you don't have good communication it may not add correctly.

lis610

.......Thanks

lis610

Replaced NRF24L01+ and it is working now.
Having trouble with DHT22 it is working on MEGA, but not on Pro Mini ATMega328P 3.3V 8MHz any suggestions

hard-shovel

@lis610 I find that at 3.3 some of my DHT22s are unreliable and at 3.2V it just gets worse..
The data sheet shows the minimum voltage as being 3.3V, and i suspect my Chinese supplied items are not within specification.
while you are using a 3.3V pro mini do you have a 5V supply for the DHT22?
You will find they are much more reliable at the higher voltage.

petewill

@lis610 Great news! I echo what @hard-shovel said. I try to supply my 5v sensors with 5v power from a regulator (with the appropriate capacitors) instead of my Arduino.
