Python plugin - Solax Inverters

[syrhus]

In Domoticz settings, did you enter Local networks value like 192.168.1.* ?

[dospider]

Yes i have. Sometimes when i try to add it again it says that is having problems adding new hardware.

[syrhus]

Try to get the log in debug mode to see the error because without it is very difficult to understand what happened.

Just wondering: Does this plugin only work with the Pocket WIFI? I use the Pocket Lan V3.0 and would love to have this plugin work, but keep getting the following error after creating the hardware:

'/home/pi/domoticz/plugins/SolaxHTTP/:/usr/lib/python37.zip:/usr/lib/python3.7:/usr/lib/python3.7/lib-dynload:/usr/local/lib/python3.7/dist-packages:/usr/lib/python3/dist-packages:/usr/lib/python3.7/dist-packages'

This is not an error there should be more. Probably an Module is not loading. see Wiki https://www.domoticz.com/wiki/Using_Pyt ... ules_Fails

Qh

Ah, I see. I had another look at my logs and this is everything I get after creating the SolaxHTTP hardware:

2022-12-19 15:13:11.131 Error: Solax Test: (SolaxHTTP) failed to load 'plugin.py', Python Path used was '/home/pi/domoticz/plugins/SolaxHTTP/:/usr/lib/python37.zip:/usr/lib/python3.7:/usr/lib/python3.7/lib-dynload:/usr/local/lib/python3.7/dist-packages:/usr/lib/python3/dist-packages:/usr/lib/python3.7/dist-packages'.

Did yoy have local nettworks field filled in? As it should.
https://www.domoticz.com/wiki/Applicati ... stem_Setup

Else it perhaps is type error somehere in the plugin.py. Did you modify it yourself?

I thought I had to fill in the Solax's IP address when I created the new hardware. Should that be my Domoticz IP address? And I didn't modify anything in the plugin. I don't know any Python, so I'm not taking risks there.

For having this plugin run properly you have to have your local network settings filled in (menu setup - settings).
In the plugin settings you fill in the IP of the inverter.

I have my local network settings in the settings menu and also the Solax PockteLan V3 IP (as provided by my FritzBox) in the plugin settings, but I still get this syntax error and the inability to load the plugin.

[waltervl]

Did you make the plugin.py file executable?
Is it readable for the user running domoticz?
Is it the first python plugin you are running? Else check wiki https://www.domoticz.com/wiki/Using_Python_plugins for all prerequisits

[ErikM]

It's just this one is that's giving me trouble. The other Solax plugin works perfectly fine, but doesn't give me as much information. I've updated Python, the file is executable and is, as far as I can see, available.

[waltervl]

I am out of options, perhaps the developer can kick in....

Hi all,

First and foremost - many thanks to the dev for the creation of this plugin. I've recently switch to a solax inverter and am looking forward to getting some data.

Now, i've started off fresh, and am running into some troubles. Here is my error log :

Code: Select all

2022-12-23 11:20:14.214 Error: SolaX: Call to function 'onStart' failed, exception details:

2022-12-23 11:20:14.215 Error: SolaX: TypeError: 'NoneType' object is not subscriptable 

Setup and steps so far :
- Totally fresh bullseye installation, on rpi4, with latest stable domoticz.
- I've had to install python-dev for python version to appear in domoticz, and initially attempt to run the plugin.
- I've had to chmod +x the plugin.py, which has removed one initial error.
- Settings are set to accept new hardware devices
- I've input tokenID, wifi dongle S/N, domoticz IP and port.

Many thanks for any insight you may have in resolving this.

[waltervl]

This probably has to do with incorrect entering in plugin configuration;

• Domoticz IP Address

• Domoticz Port number

Is the following URL working when entered in a browser (after changing IP and Port)?

Code: Select all

http://Domoticz-IP:Port/json.htm?type=command&param=getSunRiseSet

[Ayep]

Ah well spotted, you could indeed be onto something. This command

Code: Select all

http://192.168.1.38:8080/json.htm?type=command&param=getSunRiseSet

yields a

Code: Select all

401 Unauthorized

[Ayep]

Superb, huge progress indeed.

Since I had done a fresh installation, I had forgotten to input the 192.168.1.* in the "Local Networks (no username/password)" settings.

Now json works... And I have one new device named "Solax - [myserialkey]". I assume the next devices will populate with time.

Thank you very much for your help here, I was stuck speculating on python issues... Much appreciated!

Hi Biarritz (French guy? )

Could you please try to install the latest version 1.2.2?
Let me know if you still have the issue.

[Biarritz]

Hi, Sorry no I'm not French, just like Cadillac's and Biarritz the city .
I have plugin.py version which was committed on Nov 28, 2022
And in the log is see the version number you mentioned
