No problem to add more values. Below the known values in the Growatt record.
The values I find in your record:
pv1voltage 61.6
pv1current 0
pv2voltatge 232,7
pv2current 7,7
pvtemp 35
from grott.
It is a 2 or 4 bytes value. (High and low together makes 4 bytes)
from grott.
I'm getting a value of 38,1 °C. Seems the general ballpark at least. Will see what it does during the day.
Thanks for all this. I'll let you close this if you think its done.
from grott.
Great!
What does the High and Low mean in the different attributes?
from grott.
I have made the changes (correct the pv2watt error) and added new values to the json message:
pvinput
pv1voltage
pv2voltage
pv1current
pv2current
pvtemp
I have added the new version to the repository! Can you please test it?
from grott.
I've got them in :) Thanks.
I do think the pvtemp is a bit too low. Have never seen it that low with the old implementation. More around 35 °C. Just like you said. Can you check?

Rest seems fine :)
from grott.
Maybe its the difference between 31 Inverter Temperature and 41 IPM Temperature.
Inverter Temperature is maybe sort of the ambient temperature and 41 the internal temperature of the device?
Then I would like both :)
from grott.
It really does seem to be the temperature at this moment (it is at the same location in the record as the 35 in your previous one).
You are not generating at lot energy so maybe it is lower at this moment (the actual temperature in my inverter is now 26).
The IPM temperature for your record is 27. I will add that to the JSON tomorrow (can not test it any more today).
Please look at again tomorrow when it produces more energy.
from grott.
Ok, I guess you're right. I see just before shutdown the temperature drops from around 35 to 21. So this was probably just before shutdown.
Do you know what the IPM temperature is?
Thanks for your work today. Really nice to see features get in so fast.
from grott.
I added pvipmtemperature to the jsonmessage.
I am not sure if it gives the right value. I Can not test it with my Growatt 1500-s while IPM temperature is not inserted in the record (value = 0).
IPM stands for inteligent power module. This is a major module within the inverter to generate and control the (output) power.
from grott.
For now all relevant values are added to the json string. If more values are needed please open a new issue.
