UnicodeDecodeError:

[hviljoen]

This is a great project - would love to get it going... Having trouble towards the end though...

C:\Projects\deye-inverter>py InverterData.py Traceback (most recent call last): File "InverterData.py", line 109, in parameters=json.loads(txtfile.read()) File "C:\Users\henni\AppData\Local\Programs\Python\Python37\lib\encodings\cp1252.py", line 23, in decode return codecs.charmap_decode(input,self.errors,decoding_table)[0] UnicodeDecodeError: 'charmap' codec can't decode byte 0x81 in position 1035: character maps to

If line 108 is changed to:

with open("./DYRealTime.txt", "rb") as txtfile:

Then the following error is produced:

Traceback (most recent call last): File "InverterData.py", line 106, in response=twosComplement_hex(str(''.join(hex(ord(chr(x)))[2:].zfill(2) for x in bytearray(data))+' '+re.sub('[^\x20-\x7f]', '', ''))[p1:p2]) File "InverterData.py", line 13, in twosComplement_hex val = int(hexval, bits) ValueError: invalid literal for int() with base 16: ''

try the other way around

python ./InverterData.py

and share if this works for you.

[hviljoen]

Thank you very much for your prompt response:

Same error (Im running the code as is , no changes from my side)

C:\Projects\deye-inverter>python ./InverterData.py Traceback (most recent call last): File "./InverterData.py", line 111, in parameters=json.loads(txtfile.read()) File "C:\Users\henni\AppData\Local\Programs\Python\Python37\lib\encodings\cp1252.py", line 23, in decode return codecs.charmap_decode(input,self.errors,decoding_table)[0] UnicodeDecodeError: 'charmap' codec can't decode byte 0x81 in position 1035: character maps to

[jlopez77]

ok, let me try something

with open("./DYRealTime.txt", "rb") as txtfile: parameters=json.loads(txtfile.read().decode("UTF-8"))

try this. It should work fine.

[hviljoen]

Unfortunately not...

does your inverter S/N start by 17?

It looks that the data retrieved does not match what is expected.

[hviljoen]

It actually does not - it starts with 21*

:(

[jlopez77]

Then I'm sorry, this script works with S/N 17* I can't help you decoding the S/N 21 as long as I don't have one.

If you don't mind, I will close the issue.

[hviljoen]

Thank you very much for your assistance - any pointers on how I should go about decoding this for 21, then I can maybe contribute ?

[tomislavravic]

@hviljoen, I have taken the script and customised it a bit. I am happy to share it with you and see if it works for your inverter. It doesn't give you all the info, but the main stuff. Sadly, I have no idea how to contact you directly to send the script.

[tomislavravic]

It is still a work in progress which is why I haven't contributed to the project yet.

[hviljoen]

Thank you very much - I would be extremely grateful if you can send it to henning.schalk.viljoen@gmail.com

Im extremely frustrated with the delay in data from the Solarman app, hence the reason im want to push this into my Smart Home Application

thank you very much!

[tomislavravic]

Cool, mailed you the script.

If you don't mind, share here the changes and I can pinpoint you to get all the data. Hopefully few parameters will differ...

[cmpGI]

@tomislavravic could you please share the same with me as well? (email: zzaskoczenia1@gmail.com)

@tomislavravic @hviljoen Could you please share the changes for the 21xxxxx ? Regards, w00dst0ck

@hviljoen able to share the script? thank you very much
