SainSmart iMatic relay board with RJ45

Hi guys
Is there any way to control that board from Domoticz? (
http://www.sainsmart.com/sainsmart-imat ... d-ios.html)
I bought it hoping it will allow HTTP GET requests but id doesn't
There are some clues about that relay board (8 channel but it's almost the same):

But I'm not a programmer and it doesn't tell me anything...

First: welcome to this forum!
I think the Python script is perfectly usable with Domoticz.
Put the script on your Pi (domoticz folder > scripts).
Then create a virtual switch (create dummy hardware at Setup > Hardware), then go to 'Switches' tab and click on 'Manual switch'. Choose the dummy hardware from dropdown. Then fill in a name and choose on/off. Protocol doesn't matter because it is virtual.
Then when you have made the switch, click the 'Edit' button and at the 'On action', fill in something like this:
Code: Select all
script://path_to_script/relay.py 8 1
For the 'Off action' you fill in almost the same, but this time the off command:
Code: Select all
script://path_to_script/relay.py 8 0
(not sure if zero means off, but it probably does)
Hope you can get it working that way
Edit: Looked at the Python script again, but i think his blog messes up the code. The '&', '<' and ' " ' are replaced by HTML alternatives.
Try this version that i corrected:
relay.py
Code: Select all
from socket import *
import sys
if len(sys.argv) != 3:
sys.exit(2)
relay = str(sys.argv[1])
state = str(sys.argv[2])
data_send = "FD0220"
if int(relay) <= 8:
data_send += "0" + relay
if int(state) == 0:
data_send += "00"
elif int(state) == 1:
data_send += "01"
elif int(relay) == 9:
data_send += "F8"
if int(state) == 0:
data_send += "80"
elif int(state) == 1:
data_send += "88"
data_send += "5D"
s = socket(AF_INET, SOCK_STREAM)
s.connect(("192.168.1.4", 30000))
s.send(data_send.decode('hex'))
data = s.recv(4)
print(data.encode('hex'))
Be sure to change the IP to that of your board.

Haha it was not meant like: you didn't welcome yourself!
I saw this was your first post here, so i wanted to welcome you here
By the way i don't have this relay board, so can't help trying. Just translating/helping what i see on the (second) page you gave me.

Ok... I realized, that I didn't have python @ my raspberry (I've got it now
) but when I'm trying to run that script error appears:
Code: Select all
pi@raspberrypi ~/domoticz/scripts $ sudo python relay.py 8 1
File "relay.py", line 1
Script started on czw, 2 kwi 2015, 20:25:47

Can't help you with that unfortunately. My coding skills are insufficient.
Maybe someone with better coding skills comes by and is able to help.

Ok so mainly it was wrong some tabs and spaces...
I've added working one as attachment.
But I have another problem
When I'm using that in Domoticz it generates error:
Code: Select all
2015-04-02 22:43:59.154 Error: Error executing script command (/home/pi/domoticz/scripts/test.py). returned: 512
It was Error 32256, but afer I've changed attributes of the script file to 755 (chmod +x file.py) it changed to error 512...
It works @ console without any problem.

Ok, I think, that I've found a source of the problem. I assume that Domoticz runs python scripts @ Python 3. That script works only with Python 2. For a programmer it wont be a problem to fix it
I hope that some of u can help?
When I'm trying to run that script @ Python 3, I get an error:
Code: Select all
Traceback (most recent call last):
File "/home/pi/domoticz/scripts/test.py", line 29, in <module>
s.send(data_send.decode('hex'))
AttributeError: 'str' object has no attribute 'decode'

Can you please explain how you got it working, and post the script here?
I think other users who maybe have/will buy the same board are interested in it!

Hi,
I'm the guy from the blog!
The code is indeed for Python =< v2.7
I have updated the blog with a new link to the code which has a more proper format, that fixes the indent and the html fuck ups.
In case someone needs this code for v3 and up, personal message me and I'll give it a try.

Hi,
I'm going to buy Imatic relay with 8 relay onboard.
Can you confirm it will work with Domoticz?
Thank you.

I was finally able to get the 16 relay module
working with Domoticz.
I am not much of a coder but I was able to cobble together some working code from other sources. For some reason the code I found worked great running from SSH but when I tried to run it as an On/Off Action it wouldn't run. After a lot of trials I figured out that for some reason I could not pass two arguments through the On/Off action.(Probably just something I was doing wrong). So I simply made two python scripts one for On and one for Off
I also couldn't decipher their code but I was able to use it to make a list of the commands for on and off so my script uses a list instead of code to generate the on/off commands.
To use these put these in your:
/home/pi/domoticz/scripts/python folder
SSH into that folder and run
sudo chmod +x relayOn.py
sudo chmod +x relayOff.py
Create a Dummy Swith
Under On/Off Action point to the files like this, changing the argument to the relay number you want to control:

Not the most elegant code, but it works for me, I hope it works for others.
