exit Arduino ide, download latest Master library 1.4.1

Patch file RF24_config.h (xxxx\MySensors\utility) to enable softspi,

uncomment (remove //) #define SOFTSPI

and change pin numbers as below:

const uint8_t SOFT_SPI_MISO_PIN = 15;
const uint8_t SOFT_SPI_MOSI_PIN = 14;
const uint8_t SOFT_SPI_SCK_PIN = 16;

Connecto radio and gateway as per instructions for ethernet gateway except MISO, MOSI and SCK.
These connect as below
radio MOSI to arduino A0,
radio MISO to arduino A1,
radio SCK to arduino A2.

start arudino ide 1.5.8, open Ethernet Gateway sketch and amend/add below lines

add this line: #include <DigitalIO.h>

comment UIPEthernet.h (//#include <UIPEthernet.h>)

uncomment Ethernet.h (#include <Ethernet.h>)

and choose IP address

@Velo17 I am still on IPv4. I use DDClient as an update agent. I think it works with majority of providers such as NO-IP and DYNU.

@BartE I believe what you are looking for is called bezel - check this website.

As for cover you could modify general pvc electric box or have one printed.

@portals I had same issue - see this thread.

Download latest library, disable debug and follow @BulldogLowell advice. I managed to get dynamic memory to 75% and that seems sufficient - it has been running for a week now without issues.

@Oitzu I am only not sure whether Vera supports CH340.

@reza if you are looking for solution to control relays without buttons then you can use default mysensors relay-actuator sketch.

You only need to change this line according to the number of relays you want to control (this will work with 2 and 4 channel relays).

#define NUMBER_OF_RELAYS 1 // Total number of attached relays

For 8 channel I think you would need custom sketch.
Check this thread. Sketch posted there allows you to assign individual pins.

@p0lar, did you do everything as described in this thread?

Can you ping the gateway?

I've used below sketch with 1.6 development version; it compiles also with 2.0.0 but I have not tested it. This sketch uses toggle buttons.

//MultiRelayButton Sketch, MySensors 1.6, toggle switch

#define RELAY_OFF 1                     // switch around for ACTIVE LOW / ACTIVE HIGH relay
//

#define noRelays 4                     //2-4, define number of relays
const int relayPin[] = {14,15,16,17};          //  relay pins - should match noRelays
const int buttonPin[] = {3,4,5,6};      //  button pins - should match noRelays

class Relay             // relay class, store all relevant data (equivalent to struct)
{

@TimO thanks, that's great. Do I have to change the bridge name (gateway) for the second bridge to something else? Can I use same node IDs on both gateways?

Bridge mysensors:bridge-ser:gateway [ serialPort="/dev/pts/2", sendDelay=200 ] {
	humidity 		hum01 	[ nodeId=172, childId=0 ]
	temperature		temp01 	[ nodeId=172, childId=1 ]
        light			light01 [ nodeId=105, childId=0  ]
        light			light02 [ nodeId=105, childId=1 ]
  }
Bridge mysensors:bridge-eth:gateway [ ipAddress="127.0.0.1", tcpPort=5003, sendDelay=200 ] {
	humidity 		hum01 	[ nodeId=172, childId=0 ]
	temperature		temp01 	[ nodeId=172, childId=1 ]
        light			light01 [ nodeId=105, childId=0 ]
        light			light02 [ nodeId=105, childId=1 ]
  }

@Reza below is example for 4 channel relay

#define NUMBER_OF_RELAYS 4

It is that simple. If you will use this sketch then connect relays to pins 3, 4, 5 and 6.
You will be able to control each relay independently.
Relay actuator sketch allows you to control relays only via controller ie Veralite. Relay actuator with button sketch allows you to control relays via controller AND physical button (light switch).

Hi,

I just upgraded Linux Openhab version from "openHAB 3.1.0.M2" to "openHAB 3.1.0.M3". Since upgrade I cannot use / activate MySensors binding anymore (it worked in previous version - M2).
I cleaned openhab cache, rebooted computer; feature:install openhab-transport-serial and feature:install openhab-core-io-transport-mqtt are properly installed and active. When I place Mysensors.jar to Addons folder the file gets recognized but it is listed only as Installed, not active.

openhab> bundle:list | grep MySensors
266 x Installed x  80 x 3.1.0.202012312203      x openHAB Add-ons :: Bundles :: MySensors Binding

Log shows following error:

Does anyone know how to resolve this issue / install missing requirement?
