I made some changes but i'm not able to test it
Can you try version 5.0.2

If this is not working i'll add more logging in debug to see what is happening

Updated the beta, now running 5.0.2, nothing changed. I can control all devices but only the awning has no status update. There is another issue, if a device is moving, i can see in the logging that a fast device update should be active, every 10 sec, but the devices are updated every 20sec. I saw this also in earlier versions of the beta.
I created a debug somfy logging when a rolling shutter was active, after that the awning was active. I don't think i can upload it here, the file is about 6000kb

Can you create an issue on git.

Ok. Going to create an issue.
For your information, deviceClassTrig is allways "Unknown".

Version 5.1.1 has been released

It has been tested but not with every devices.
If you have any finding please report on git about is

The parameters in the hardware setup has been relocated for some settings so you need to change some fields if you upgrade from an older version.
When not familair with the plugin checkout the readme for for more information.

Hi Patrick,

I was ready for an overhaul and switched to a clean Trixie (Debian 13) OS on my Raspberry Pi 5.
I can't get your plugin installed, or at least, I can't see any devices.
Could this be due to Trixie? I don't see any error messages in the log as far as I can tell.

Thanks to Jan Jaap's help, I've been running my tilt-function blinds on Bookworm for a long time. But even the older version that runs successfully there doesn't work on Trixie. Very frustrating, and most AI tools offer little solace. Do you have any ideas?

I've no RPI or running on Trixie so i can not do a test
If i've some time a i'll setup a VM with Debian 13 and do some testing

It is possible that it is a python version issue and breaks some features
Can you enable the debug logging and monitor what is happening and check the Somfy.log

Maybe better to raise an issue on Git for this

Just for information, i am running the plugin, latest master, on Trixie, Rpi3b+, Domoticz 2025.2. No issues here.

I've found the issue
In the later releases the creation of the devices is broken
So when you do an update it works.

There is not a quick fix (yet) and i need to dive in to this
The best way is to go back to an old release.

see https://github.com/MadPatrick/domoticz_somfy/releases
Maybe 4.2.16 is the best to use for now.


Only the sunset JSON can be giving an error due login setup
You can change the IP 127.0.0.1 in the plugin.py to your domoticz IP

ok. Just released version 5.1.6

Please test and let me know

Re: Support for Somfy Connexoon and Tahoma

I have tested the latest version 5.1.6.
For me it works without problems. Just some remarks/ questions, what is the advantage of using a config file? The only parameter that is used in that file (at this moment) is the fast polling time (temp_time). The other parameters are set in the parameters section. Is it possible to add the fast polling time also in the parameter section, in the same Refresh Interval field?
I think it looks nicer if the Refresh Interval field has the same width as the three other fields.
Thanks for the updates.

Hi Rik
I agree with you and i'm currently working to remove soe of the settings in the config.txt file
The problem is the limitation within Domoticz in the use of parameter fields

I've pushed a new version in the beta branch.
The config.txt is now limited and no reload by changes of the config.txt. Only on start of the plugin of update in the setting page

Moved to beta 5.1.7. No issues. I can't test the creating of new devices.

Made some changes in plugin.py:

Code: Select all

        <param field="Mode2" label="Refresh interval" width="100px" default="30;900;15"/>
        <param field="Mode3" label="Night Mode" width="100px" default="30;60"/>
and

Code: Select all

        # Check Mode2 and set default as empty or invalid
        if not Parameters.get('Mode2') or ';' not in Parameters['Mode2']:
            Domoticz.Log("Mode2 leeg of ongeldig, instellen op standaard 30;900;15")
            Parameters['Mode2'] = "30;900;15"

        # Check Mode3 (sunrise;sunset; delay)
        if not Parameters.get('Mode3') or ';' not in Parameters['Mode3']:
            Domoticz.Log("Mode3 leeg of ongeldig, instellen op standaard 30;60")
            Parameters['Mode3'] = "30;60"

        try:
            sr_delay_str, ss_delay_str = Parameters['Mode3'].split(';')
            self.sunriseDelay = int(sr_delay_str.strip())
            self.sunsetDelay = int(ss_delay_str.strip())

        except Exception as e:
            Domoticz.Error("Invalid Mode3 value, using defaults 30;60: " + str(e))
            self.sunriseDelay = 30
            self.sunsetDelay = 60

        try:
            day_str, night_str, tmp_str = Parameters['Mode2'].split(';')
            self.dayInterval = int(day_str.strip())
            self.nightInterval = int(night_str.strip())
            self.temp_delay = int(tmp_str.strip())

        except Exception as e:
            Domoticz.Error("Invalid Mode2 value, using defaults 30;900;15: " + str(e))
            self.dayInterval = 30
            self.nightInterval = 900
            self.temp_delay = 15
Now there are 3 variables in the Refress Interval field. In the config file i have disabled the 2 temp times.

Hi,

I've been working on my RPi 5 with Trixie for days now, but I can't get any devices to show up in Domoticz.
When I try to retrieve data from my Tahoma Classic in the terminal, I see the following, which shows that the token, the IP of the Tahoma, and the PIN are correct and working properly.

Code: Select all

Naam                      | Type (uiClass)
--------------------------------------------------
IO (10459781)             | ProtocolGateway
Aanraakgevoelige knop     | Pod
Rolluik kleedkamer        | RollerShutter
Jalouzie                  | ExteriorVenetianBlind
Rolluik slaapkamer        | RollerShutter
Rolluik Lynn              | RollerShutter
Rolluik Tess              | RollerShutter
You would do me a huge favor if you could walk me through the process of installing this plugin step by step. I'm starting to lose hope.

Thank you so, so much in advance for your help!

Which version are you using?
Please try it with the latest beta version (main should also work)

Enable debug logging to see what is happening
I just tried on a clean debian 13 install and it creates the devices

Did you add your IP to your DNS

Code: Select all

Your Somfy box needs the traceable in your network. To do this, you need to link your Somfy Box PIN to the Somfy Box IP address. Add your Somfy Box PIN number to the IP in your local network in etc/hosts or in your DNS Server
192.168.1.1 1234-1234-1234.local


192.168.1.1 is the IP of your Somfy box
1234-1234-1234 is the PIN number of your Somfy box and don't forget to add .local to the PIN number

Hi Patrick and others,

I finally got it working. I used the following git clone and suddenly all the devices appeared! Phew, what a relief!

Code: Select all

git clone https://github.com/MadPatrick/domoticz_somfy.git
First I cleaned everything up, then restarted, and other than that I really don't know what else is/was different.
I can see now that I was using version 5.1.8, but that's beside the point. From now on, I'm going to sit very quietly ;-)

Thank you very much for sharing your thoughts, Patrick. Occasionally, it remains a matter of trial and error.
