GW20K-ET Some values are always 0
t4e-dev opened this issue · 8 comments
Hi,
thanks for your hard work!
I have an inverter GW20K-ET
meter_e_total_exp: Meter Total Energy (export) = 0.0 kWh
meter_e_total_imp: Meter Total Energy (import) = 0.0 kWh
The values, that are needed for Homeassistant Energy Dashboard are always 0 in the requests.
Sadly I do not really know how to analyse the datagram.
Solar-Go seems to successfully decode these values. So in theory, they are there .-)
I also have the issue that Semsportal is no longer available once HomeAssistant starts polling the inverter.
If there is a solution for that I would be thankful as well.
Thanks for your help...
I have GW15K-ET. Same problem. Meter Total Energy reads always 0.
Also PV2 panels status is wrong (always reads "not connected"), PV1 string power is equal to PV power (but I have two strings), PV2 power always reads 0, but PV2 current and PV2 voltage reads ok.
If you set polling interval for 180sec or above, SEMS communication is restored
Is there anything I can help to include these devices ?
Provide datagrams, or something like this ?
GW15K-ET in my home and same for me here too.
The entity „Total energy export/import“ is working, but it seems that this is the oberall energy coming from the inverter. Could there be a way to calculate the meter total energy from theese values?
It seems the ETT inverters use different modbus registers than ETU.
I can try to reverse engineer some data from mobile app again, but can't promise when or if possible at all ...
We now have the manufacturer's description of modbus registers of ETT inverters and there are no relevant differences to ETU inverters. So the "meter" values should be read and decoded properly.
Couldn't it be something is wrong with your meter installation ?
I have just realized there are additional "CT2" meter registers at address 36047, 36049.
Will investigate ...
Sounds great!! Thanks a lot. Wish I could help :-)
Library with the "CT2" was released and HACS integration was released as weel, hope it helps.
