Telnet Type Data to Domoticz Help Topic is solved

[NickHead]

Managed to get the Socket on the PI Simon.

Tried the same program on the Domoticz LUA, worked in a fashion, however, due to the program
needing to be connected to the Bridge, it was connecting every time it was polled.
I have to find a way now to connect it, and keep the connection.

Code: Select all

>lua -e "io.stdout:setvbuf 'no'" "ESPInverter.lua"

And the output is more standard/readable rather than hex digits.
This is still running on the PC, through the wireless bridge.

Update:

Decided LUA was not easy enough to use.

Ported it over to Python, Job Sorted, took some time to reverse engineer what I had already
but it's working. Few final polishing routines to create and game over. off to do something new
with the gear..

[simonrg]

Glad you have got it all working.

Curious to understand what the Python looks like, it would be a nice example to post up on the http://www.domoticz.com/wiki/ESP8266_WiFi_module.

[NickHead]

Still in " Sorting it out mode". Tightening all the slack programming out as best I can.
Limited time after work as there is no sun and nothing comes from the inverters, so I
have to do it on sunny day and they are few and far between here at the moment.

It's working in a fashion but I just can't keep it logged in when the sun goes down. The program
flags an error, if I can sort it out it will be use-able.

Just been trying a python inverter simulator I wrote, need to run it on another pi really as the RS485 converter
is not knowing whether it's coming or going.

[NickHead]

Here's a picture of the circuit I made.
An ESP-Programmer/breakout that I use.

ESP-8266-01, RS485, Power Dropper, Reset and Program buttons
with headers for GPIO and RS232 in/out.

Hi all,

This looks like what I was hoping to do with my denon amp. I need to pole the power state of the amp by sending the command PW? And read the reply and if it's on then switch a switch in domoticz to on. That's it in its simplest form.

Any ideas?

Cheers

[NickHead]

Do you know what the data-stream format is ?

For my inverters I have a print out of the commands in RS485 format.

I started with a simple ESP Bridge from wifi-tcp but I changed it over to a commercial Wifi-Serial-Ethernet bridge, it
doe the same thing but all in one and has 2 serial ports, works like a dream and frees the ESP for something else.

You need the protocol first then write the program to see if it decodes/encodes it.

I am not an expert on programming I just do a lot of asking and trial / error .

[simon_rb]

Hi,

I think its pretty simple, below is the documentation I found. Thank you

http://openrb.com/wp-content/uploads/20 ... V7.6.0.pdf

[NickHead]

Wow, that's a pretty comprehensive list.

Too late for me to ingest at the moment, I will look tomorrow and see if I
can be of any help to you.

Off to bed.

[simon_rb]

I just need to send the PW? and get Domoticz to understand and act on the reply.

Thank you very much! Sleep well.

[NickHead]

Do you know what data is sent from the Denon after PW? has been sent to it.

I am assuming you have an IP Address for it, and a Port Number.

I can send PW? over the network to an IP/Port. Depending on the result received is what
determines what happens next.

I cannot drop out of a Python Loop without knowing what is received, even better if its a CR then
the length is/can be fixed.

[simon_rb]

Yes I have an IP address and port but how can I send the command and let you know what the answer is?

[NickHead]

You will need the libraries installing, and the Denon/Domoticz Parameters modifying.

Code: Select all

#!/usr/bin/env python
import os
import sys
import socket
import urllib, urllib2, hashlib
###############################################
# Denon Amp Settings

denon_host = "192.168.0.231"
denon_port = 8081
###############################################
#domoticz settings

domoticz_host         = '192.168.0.5'
domoticz_port         = '8080'
domoticz_url          = 'json.htm'
port = 8080
################################################
def CallData():
	Text = "pw?"
	s.send(Text)		 
	 		       		
try:
    	
	s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    		print "			 Socket successfully created"
except socket.error as err:
		print" "
s.connect((denon_host,port))
print "                      Host =",denon_host," Port = ",denon_port
print "			 Connecting to Denon Amplifier"

CallData()

[NickHead]

P.S

The program will not actually receive anything.

It just sends pw? to the Denon.

If I don't know how the data is formatted, I cannot do anything to continue.

As I said, I am no expert on this, only been programming a few months

[NickHead]

Code: Select all

s.connect((denon_host,port))

needs changing to

Code: Select all

s.connect((denon_host,denon_port))

[simon_rb]

Thanks for that, I am just trying to find out what the Denon would return so we can act on it. Must be a way of sending the PW? and view what is returned.

[NickHead]

There is, but I aint done that yet, and wether it would work is another story.

You could always try entering other commands in to the text string to see if it changes channels/volume or whatever/

I simple read of about 10 bytes would suffice I would reckon.

i am doing too many things here at the moment , I have to rewrite my SolarPanel programs as well
not only that , I have to to work in a bit

[NickHead]

This will/should receive 6 characters from the Denon Stream.

It will print the character chr(DA[Data}) 6 times. with the associated Decimal Number Next to it.

Its a start.

Code: Select all

#!/usr/bin/env python
import os
import sys

import urllib, urllib2, hashlib
DA = [1,2,3,4,5,6,7,8,9,10,1,2,3,4,5,6,7,8,9,10]

port = 8080
################################################
def CallData():
	Text = "PW?"   # Changed as it was lower case
	s.send(Text)

def ReceiveData():
	DStart = (s.recv(1))
	for Data in range ( 1 , 6 ):                                   
		DA[Data] = ord(s.recv(1))			 
		print chr(DA[Data])," ",(DA[Data])	       		
try:
    	
 	s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
 	print "			 Socket successfully created"
except socket.error as err:
		print" "
s.connect((denon_host,denon_port))
print "                      Host =",denon_host," Port = ",denon_port

Does this help, it uses the PW? As an example...
