@ActionHenk
You could have saved yourself a lot of trouble by checking my post of 19 october.
But glad you managed to get it up and running.

Hello,
RPI3 + Raspbian Stretch + Domoticz stable V4.9700 + RM PRO+

It looks like I am close to use the Broadlink inside Domoticz,
I am stuck now with the import function, no button is active:

• webstart

• import

• generate

Can you put in debug mode and post the result ?

Hi all, I'm new and trying to make this plugin work.
Using Win 10 and latest stable app
Im currently stuck with the message
"Error: (BroadlinkRM2) failed to load ' plugin.py', Python Path used was ..."
I tried to install and uninstall different Python versions, only 3.4
Let me install the plugin since crypto demanded it...but from.that step, I get the error above...
Any clue?
Thanks ms for any help

Hi,
if you go to domoticz / about let show what you have.
this is mine:

UPDATE: I used stretch raspbian 2018-10-09 version with domoticz 4.9700. You definitely have to pip3 uninstall pycryptodome. No need to install Crypto or libcurl4 or libssl. Just for your info. Works as a charm now. So in total:

Code: Select all

curl -L install.domoticz.com | sudo bash

sudo pip3 install broadlink
sudo pip3 install pyaes

sudo pip3 uninstall pycryptodome

copy plugin files to plugins/broadlink/
chmod +x plugin.py
chmod +x plugin_send.py
chmod +x plugin_http.py
chmod +x plugin_http.sh
sudo service domoticz restart

Tnx that work for me. I see broadlink (rm3 mini) in hardware and switches but when I try learn new IR code from IRcontrol I got very often this log:

2018-11-19 01:58:39.172 (Broadlink) b'\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00'

2018-11-19 01:58:39.181 (Broadlink) Update 1:'20' (Broadlink - Command)

later when I put test button, broatlink no sending IR code (no blink white LED). I need about 10 attempts and I gets the correct code and then test button eorks correctly and I can save IR ccode.

You need to be very close the broadlink device during learning process....

I'm 5-10 cm from broadlink when during learning process. Restart service domoticz help but only for once code learning. I have the last version of the firmware broadlink v55. Log debug:

@hose2001
need to check deeply... as workaround, you can use the application and import the code.

Ok thx, I imported *.ini from e-control it"s work fine. but I have anothrer problem. Domoticz with broadlink works okey for one day. When I try connect to domoticz in next day - domoticz offline. Raspberry no response for ping or ssh and every morning is this same.
Only reboot can help.

My device:
Raspberry Pi 3
Raspbian 2018-10-09-raspbian-stretch-lite
Broadlink RM3 mini
Plugin broadlink 0.9
Domoticz Version 4.9700 (June 23th 2018) stable

I installed from this instruction:

sudo apt-get install python3-pip
sudo pip3 install broadlink
sudo pip3 install pyaes
sudo pip3 uninstall pycryptodome

copy plugin files to plugins/broadlink/
chmod +x plugin.py
chmod +x plugin_send.py
chmod +x plugin_http.py
chmod +x plugin_http.sh
sudo service domoticz restart

thanks in advance;
zsolt

you should be able to have more than once.

[kubrik]

Sorry you have trouble, but not really related to broadlink plugin itself. once you have a system with python installed in right way, as required for Domoticz, you should not have problem to run broadlink plugin. I'm not able to provide lots of help on linux, I run all my system on Windows.

But happy to see that you have been able to have it running again

Hi zak45,
i've a working domoticz (3.8796) with a working plugin in a raspbian jessie.
I've tried to upgrade domoticz both stable or last beta version, but domoticz stop work...untill i disable the broadlink plugin (viewtopic.php?f=6&t=25751)
So i don't think it's a python issue (it's working with actual domoticz version).
Can you give me some hints?

Perhaps i'm seeing the light....
Progress:
after i've upgraded the plugin to 4.1 (and not only domoticz) i got this error:

Then i moved away this folder:
/usr/lib/python3.4/lib/lib-dynload

mv /usr/lib/python3.4/lib-dynload /usr/lib/python3.4/lib-dynload.old

Domoticz started and plugin seems to work...i'll do some tests in these days...

ps: If i switch back to old domoticz version with plugin 3.0, i'd to move back also that lib folder.

Hey zak45,
I see that You have domoticz on windows.
I really want your plugin to work stably on domoticz, that's why I changed the system. I have a problem installing your plugin on windows. I installed python 3.5.3 and when I run setup.exe as an administrator, I have such an error. I copied files to C: / ProgramFiles x86 / Domoticz / plugins / BroadlinkRM2. I have no broadlink on the device list. I'm sorry but I've used domoticz on raspberry / raspbian before and I'm a bit lost here.
Can you help and write a detailed installation guide?
Thank you in advance

2: what is the proper folder for Folder to store ini files (RM2/RM mini3): I point at /home/pi/domoticz/ but not sure that the one
3: what doest the debug on of function do … its set to off but the log domoticz file is still flooded with messages
thanks for your help

1: not managed
2: folder where you can keep safe your ini files, not domoticz folder itself, during upgrade can be lost.
3: debug provide much more information. normal operation, need to be unset
