Noob help needed please

Developing with LIFX
#1

I am a bit of a noob here and am currently stuck.
I am attempting to set up a tile array controlled by my ISY-994 home automation controller.
The ISY has the ability to send a binary string to an IP as a resource.
I can currently turn on the tiles with sending to the Tile IP
42;0;0;52;180;60;240;132;0;0;0;0;0;0;0;0;0;0;0;0;0;0;1;13;0;0;0;0;0;0;0;0;117;0;0;0;255;255;232;3;0;0
Like wise off
42;0;0;52;180;60;240;132;0;0;0;0;0;0;0;0;0;0;0;0;0;0;0;11;0;0;0;0;0;0;0;0;117;0;0;0;0;0;232;3;0;0
or Red

Where I am stuck is implementing SetTileEffect (719) to use firmware commands for Morph and Fire
719 it > 32 bits
Suggestions please on the packet
Thank you in advance

Hello,

I’m not sure why those messages you mention would work because they aren’t valid.
EDIT: actually, sorry, I thought your strings were hex, but they were integers, your messages are valid ! except the target field should be the mac address of your device and when you do that tagged should be false.

SetTileEffect looks like this

You can work out what messages to send by using photons.

so if you have python3.6 or above, create a virtualenv and do pip install lifx-photons-core in it and then say something like

lifx lan:tile_effect match:cap=matrix flame --debug

The --debug mean it’ll print out the bytes it sends and receives.

Or you could create a script like

from photons_messages import DeviceMessages
import binascii

message = DeviceMessages.SetPower(level=0, source=123, sequence=0, target="d073d5001337")
print(binascii.hexlify(message.pack().tobytes()).decode())

messages are here https://github.com/delfick/photons-core/blob/master/photons_messages/messages.py

Don’t hesitate to ask more questions!

Thank you delfick
I managed to update python to 3.7 on a pi and get photons up and running
i can see the string it is sending to the tiles
is there a way to select an output format to the string format I mentioned above ??
…Barry

#4

You could always do something like

python -c 'import binascii, sys; print(";".join(str(i) for i in binascii.unhexlify(sys.argv[1])))' 2a000034b43cf0840000000000000000000000000000010d000000000000000075000000ffffe8030000
#5

appears to have a syntax error that I cannot figure out, but I am a nothing on python

#6

What is erroring? If you paste the error here I can help work out why it complains

#7

C:\WINDOWS\system32>python -c ‘import binascii, sys; print(";".join(str(i) for i in binascii.unhexlify(sys.argv[1])))’ 2a000034b43cf0840000000000000000000000000000010d000000000000000075000000ffffe8030000
File “”, line 1
'import
^
SyntaxError: EOL while scanning string literal

#8

oh, I see, yeah windows terminal is very annoying.

I suggest putting the command in a file

import binascii
import sys

print(";".join(str(i) for i in binascii.unhexlify(sys.argv[1])))

and then

python3 convert.py 2a000034b43cf0840000000000000000000000000000010d000000000000000075000000ffffe8030000

Thank you for all the help here :grinning:
called in some help and get a string that looks like what the ISY wants, but the strings dont turn on effects, just turn on last setting code is below, am I missing something ??
…Barry

import binascii
import sys

strIn = sys.argv[1]
strOut = “”
if(";" in strIn):
data = strIn.split(’;’,-1)
for temp in data:
strTemp2 = hex(int(temp)).split(‘x’)[1]
#print(temp + " " + strTemp2.zfill(2))
strOut+= strTemp2.zfill(2)

print (strOut)

else:
for i in range(0, len(strIn) - 1, 2):
str2Char = strIn[i:i+2]
strOut += str(int(str2Char,16)) + “;”
print (strOut[:-1])

#10

When you paste code, if you put three backticks (```) on their own line before and after code, it gets formatted in a way that keeps indentation

If you want to create a hex string from the semicolon separated integers you could do something like

import sys
print("".join(f"{int(i):02x}" for i in sys.argv[1].split(";")))

and then with photons you can see what that packet is by saying

lifx unpack --silent -- 2a000034b43cf0840000000000000000000000000000010d000000000000000075000000ffffe8030000

If you have jq installed you can also pipe it into that to make the output a bit easier to read

lifx unpack --silent -- 2a000034b43cf084... | jq
