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?

@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,

is it possible to configure multiple MySensors gateways (ie one serial and one ethernet) on single Openhab server?

@yveaux is there any way to convert flow in l/min to pulses per liter?

Another user posted below info; is that accurate?

• • Flow meter using Honeywell C7195A2001B which has a hall sensor that pulses at 7 Hz per liter/min
• we count only upgoing pulses, so in our case we get:
• 7 pulses per second at 1 l/min
• 420 pulses per liter
• 420000 pulses per m3
• Flow meter Caleffi 316 which has a hall sensor that pulses at 8.8 Hz per liter/min (according to specs)
• In reality the frequency is about 30% lower in my case, so we have to correct this with a factor of 1.3.
• 8.8 pulses per second at 1 l/min
• 528 pulses per liter
• 528000 pulses per m3
• 528000/1.3 = 406154

Hi,

I would like to use YF-B5 water flow sensor with default mysensors water-meter sketch. I need help getting correct PULSE_FACTOR value based on below specs:

1 Appearance Product identification clear, accurate and meet the requirements
2 water pressure> 1.75MPa
3 Operating voltage range DC5 ~ 15V
4 Insulation resistance> 100MΩ
5 Accuracy (in 1 ~ 25L \ MIN) ± 3%
6 Flow Pulse Characteristics (6.6 * Q) Q = L / Min ± 3%
7 Output pulse high> DC 4.7V (input voltage DC 5V)
8 Output pulse low level <DC 0.5V (input voltage DC 5V)
9 Output pulse duty cycle 50% ± 10%

@Mitja-Blazinsek I had similar issue. I found the cause was port 8443 itself. When I changed Mycontroller config to use another port (8442 or 8444) and opened it, I was able to access Mycontroller from external networks.

as emc2 said; alternatively if rc-switch doesn't work for you (unlikely) you can also try with Remoteswitch library.

@NeverDie they do, but many people don't notice it or find it unbearable. It also depends on type of filament; ABS smells like hot plastic, PLA like something sweet (it is derived from sugar). I keep mine in the house but I put it inside DIY enclosure - mainly to improve ABS printing quality but as side effect it also contains smell.

@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.
