Python plugin - Solax Inverters

[syrhus]

I created Domoticz plugin to retrieve inverters production data from Solax Cloud as they changed their APIs and no more usableb locally.
First, on the solaxcloud web site, you have to claim a TokenID from the Service menu.

You can add several inverters and get the total like below:

onduleurs_solax.png (83.43 KiB) Viewed 3442 times

The plugin is available here solax_inverter

Thank you for your work, I installed the plugin and configured it.
It updated once for the first startup, but after that no updates are coming through
In the log I find some entries that could point to the problem in the bottom 2 lines

Do I need to change something else in order to have this plugin working?

If I look at the system settings, the for my location the I see that SunRise and SunSet are like this, so from a system perspective (and outside) the Sun is up
SunRise: 07:29, SunSet: 18:13

[syrhus]

Hello itsbvka,

Are you sure to allow local connection to Domoticz in the Domoticz parameters? (192.168.2.*; ...)
The sunset and sunrise time are queried but nothing in the log so it seems to failed.

Hello itsbvka,

Are you sure to allow local connection to Domoticz in the Domoticz parameters? (192.168.2.*; ...)
The sunset and sunrise time are queried but nothing in the log so it seems to failed.

Regards

For clarity: Local network settings in menu Setup - Settings
https://www.domoticz.com/wiki/Applicati ... stem_Setup

[itsbvka]

I found a small error in the script.
the initial value of self.sunset was not set, it was only self.sunrise that gets an initial value.
This is what is in the original script
self.sunrise = datetime.time(7,30,0)
self.sunrise = datetime.time(21,30,0)

I changed this to
self.sunrise = datetime.time(7,30,0)
self.sunset = datetime.time(21,30,0)

and now the script starts to generate meaningful info and the graphs get populated

[syrhus]

Thanks for the bug about the sunset default value.

BUT, you still have an issue because the plugin asks to Domoticz the sunrise and sunset time to override default value. In your case, this request doesn't work. Please, check your Domoticz IP address, port and if you have allow local network connection in Domoticz.
On your web browser, in a new tab, enter:
http://192.168.2.19:6144/json.htm?type= ... SunRiseSet

Do you have a json result with sunset and sunrise value?

[itsbvka]

You are right, this call does not give a proper response
However Local is set to 192.168.*.*;127.0.0.* which should allow local connections so that's not the problem
When connecting to https://192.168.2.19/json.htm?type=comm ... SunRiseSet I do get the right answer, so the problem is the port used
{
"AstrTwilightEnd" : "20:04",
"AstrTwilightStart" : "05:38",
"CivTwilightEnd" : "18:47",
"CivTwilightStart" : "06:56",
"DayLength" : "10:44",
"NautTwilightEnd" : "19:25",
"NautTwilightStart" : "06:17",
"ServerTime" : "2021-02-26 19:47:54",
"SunAtSouth" : "12:51",
"Sunrise" : "07:29",
"Sunset" : "18:13",
"status" : "OK",
"title" : "getSunRiseSet"
}

[syrhus]

Good news!
Try to change the port to 80 instead of 6144.
Regards

[itsbvka]

Indeed, that part was obvious. I should have stated in my previous post that I already did that.

Thanks for creating the plugin and the help here!

[labrag12]

i ran into some trouble.
I filled in all the information. but its wont show up under devices.
I see the below in the log.

Kind regards

Hi

What Domoticz IP address & port have you entered in the parameters?
Regards

[labrag12]

I filled in my local ip adress 192.168.2.12
It’s running on port 8020

[syrhus]

Have you tried to open your web navigator and enter:
http://192.168.2.12:8020/json.htm?type= ... SunRiseSet

Is it succeeded?

Else, could you please switch the plugin in debug mode to get more information.

[labrag12]

{
"AstrTwilightEnd" : "19:34",
"AstrTwilightStart" : "03:54",
"CivTwilightEnd" : "18:15",
"CivTwilightStart" : "05:14",
"DayLength" : "11:55",
"NautTwilightEnd" : "18:54",
"NautTwilightStart" : "04:35",
"ServerTime" : "2021-03-16 07:01:57",
"SunAtSouth" : "11:44",
"Sunrise" : "05:47",
"Sunset" : "17:42",
"status" : "OK",
"title" : "getSunRiseSet"
}

think this looks good.
Can i change it to debug mode in the pyton script ?
sorry for the questions, first time i', working with domotics

[syrhus]

In the plugin parameters, the last one is for Debug; the default is "False", change it to "True" and update the plugin.
Regards

When you have added/updated the plugin, did you previously allow to add new hardware in the Domoticz settings? Do you have a Solax device?

[labrag12]

I only have them in the hardware tab.
Its not showing up in the device list

So, please, go to Domoticz settings and check "Accept new hardware devices".
Then, go to hardware tab, select the solax plugin and click on update.
Check the log and device list.
