GoodWe Solar: get data from the new semsportal (lua script)

[pvdgulik]

I added in the calculation script the following, which takes the W from the

After reading out the powergeneration out of the device in:

PowerGeneration, EnergyGeneration = otherdevices_svalues[GenerationDeviceName]:match("([^;]+);([^;]+)")

Add:

PowerGeneration=PowerGeneration:sub(0,-2)

This resolved the problem for me.

hi,

I have updated the script to get output power, temperature of the inverter, output voltage, output current etc.
------------------------------------------------------------------------------------------------
output_power = getValue(splitString, "output_power")
last_refresh_time = getValue(splitString, "last_refresh_time")
eDay = getValue(splitString, "eDay")
work_mode = getValue(splitString, "work_mode")
temperature = getValue(splitString, "tempperature")
stroom = getValue(splitString, "output_current")
spanning = getValue(splitString, "output_voltage")

print("last_refresh_time :" .. last_refresh_time)
print("output_power :" .. output_power)
print("eDay :" .. eDay)
print("work_mode :" .. work_mode)
print("temperature :" .. temperature)
print("stroom :" ..stroom)
print("spanning :" ..spanning)


current = tonumber(stripchars(output_power, "pv:(W)"))
dayTotal = tonumber(stripchars(eDay, "sum:"))*1000
temp = tonumber(temperature)

UpdateDevice(sensorSolarPanels, current..";"..dayTotal)
------------------------------------------------------------------------------------------------
I see these vallues in the log but I do not get them into Domoticz.

I think I have to change the UpdateDevice commands and cannot get it working.

can someone help me with this?

Regards,

Sander

I'm running Domoticz V4.10055 in a docker image on Raspi3

It seems GoodWe has (again) changed something but, at least for me, the script is no longer working. Instead of the JSON data, I now get the HTML of the login page. Anybody any ideas on how to fix this?

I'm using the PHP version from @sinze and this no longer works for me either.

Same problem since wednesday 13 november 2:45

[bldewit]

Same here, nov.13.....

[sjoemie1985]

i have also some problem i think.
i see the following error in my domoticz system, any one who knows how to solve it.
or has this also to do with the problems you all got?

[CrazyFrog]

Sorry I've been very busy for a while.

I picked up this issue again today and expect next week
post a new working script here.

At this moment I already have extract the data from the site, now I just have to strip it and pass it on to domoticz.

Just be patient

Thanks a lot.
I had to add i=1 to get it working, but now it works fine.

Hello sandeman684

why did you have to put this variable, the code does not use this variable?
Could you indicate where you have placed this declaration so that other users can take it over when referenced.

Thank you in advance for the information.

I got an error at the following line:

Code: Select all

commandArray[i] = {['UpdateDevice'] = idx..'|0|'..data}

Adding i=1 here:

Code: Select all

commandArray = {}
i=1

solved this.

tx.

oops forgotten with copy-past
I have update the code above.

[Gruzi]

Thanks for the script CrazyFrog, if functions well overhere!

However, it causes an error in my log file about one time per hour:

2020-02-28 07:35:10.354 Error: EventSystem: Warning!, lua script SolarPanels has been running for more than 10 seconds

Is there a way to increase the timer for script?

[CrazyFrog]

yes you can, but with an update it is set back to 10 seconds

[sandeman684]

It seems there is still an issue with the daily production. Very often a value is used for two consecutive days, as you can see in the image. The correct values should be:
Tue 7.2
Wed 2.4
Thu 1.7
Fri 6.2
Sat 5.6
Sun 6.4
Mon 2.7
Tue 0.3
So, often the value of the previous day is used, but not always.
EDIT: it seems like the previous day is used when its value is larger than the current day value.

[Gruzi]

Same behaviour here.

Values should be (checked on Sems portal) :
Wed - 5.8
Thu - 2.4
Fri - 8.6
Sat - 9
Sun - 13.2
Mon - 4.5
Tue - 20.5

It is also remarkable that today Wed is already filled in with 20.5

@CrazyFrog @Sandeman684

I investigated further and I think that the problem Sandeman684 and I have is not caused by the script from Crazyfrog.
The script is giving Domoticz the right values for Power and Energy (I created logfiles over the day) but Domoticz doesn't process them well.
This seems a more common problem from the sensor Electric (Instant and Counter) and I found another post on the forum where I have reported this.

See my post:

Hi Sincze,

I used your PHP script but I am getting a fatal Curl error which leaves the output.errors blank and also No feedback in the domoticz log.

this is the output:

 thnx in advance!

hi

i tried to use the LUA scripts (2 versions) but both do not work

first of all the request to get the TOKEN must be wrong as I got back "0" as an answer on two different accounts within the Semsportal

where is the token used for?

the LUA script is giving errors while checking under raspbian os

Lua 5.1.5 Copyright (C) 1994-2012 Lua.org, PUC-Rio

who is able to help me out?

kind regards
