Error when trying to add Goodwe #258

Closed Oooklart closed 4 months ago

Oooklart commented 6 months ago

Its not possible to connect to Goodwe 15kw with WiFi 2.0 IMG_2999

mletenay commented 6 months ago

Does the SolarGo/PvMaster mobile app work ?

linusst commented 5 months ago

Hi, I have the same problem. Yes SolarGo and SEMS is working.

This is the log i get:

Also have the same problem, newly installed 15kw hybrid inverter. Looks like the inverter doesn't respond to UDP 8899 at all(tested with nmap), updated to latest DSP and ARM firmware(according to SolarGo) DSP: 07.7068 ARM: 08.401

Tried both Wifi and LAN connection.

mletenay commented 5 months ago

How do you then connect SolarGo ? Via bluetooth? If not, can you sniff network traffic ?

micros01 commented 5 months ago

I'm using Bluetooth to connect SolarGo. I've never been able to see the Wifi the inverter is supposed to broadcast..havent found any setting where you can turn on/off this..

mletenay commented 5 months ago

Hmm, this seems to be the same issue as https://github.com/home-assistant/core/issues/114173 It looks like the new WIFI/LAN 2.0 adapters switched from UDP to (more standard) modbus/TCP. And that one is not supported at the moment.

As mentioned in that other ticket, it should be doable, but will be a pain without real device to test with ...

micros01 commented 4 months ago

FYI.. I experimented with the modbus connection to my ET15, as far as I can tell it's read only but at least now I can get the statistics/values I need into Homeassistant, PV generation, battery and so on. Also seem to work fine adding the daily production to the Energy dashboard.

I've added everything to my Github, maybe it could help someone else.(not used to Github but I think it should work :) ) https://github.com/micros01/GoodweHAmodbus

What do you mean by read only? I have a third party module connected via modbus thru the LAN connection controlling the battery and its writing to registers. If anyone else are doing the same connecting ower Wi-Fi at the same time makes the modbus LAN connection fail but using modbus rtu at the same time works great.

micros01 commented 4 months ago

OK, found this about the modbus registers: https://forum.iobroker.net/assets/uploads/files/1666333836822-goodwe_modbus_protocol_hybrid_et_eh_bh_bt__arm205-hv__v1.7-_-read-only_20200226-1.pdf and it states "Ready only"....which I interpreted to read only for the modbus but guess I was wrong.

Then it should be possible to control charging and discharging the battery based on electrical price from the grid(which I get from another sensor in HA)? If you can hint on how to do that it would be awesome...

linusst commented 4 months ago

Use this instead https://forum.iobroker.net/assets/uploads/files/1703579717824-arm.745.esg2.et30.modbus.protocol.map.20221231..v1.pdf?fbclid=IwZXh0bgNhZW0BMQABHXcRLb0ZpNyMluMOU1YbESC-qq7E6tqPzmVHqIo23sWL3AheL7OYA5a_fg_aem_AeJDg4Y2IXxYAnOrXnNez3tsuNQNVzB0cyxXopC87s3VG7X8rW4mRa4WvMJevb3suLo

it contains RW registers as well. I found some fault in it (like wrong prefix on apperent power) and two registers that they forgot to put in (35200 e total buy energy and 35195 e total energy).

mletenay commented 4 months ago

FYI - I've just added the standard Modbus/TCP to the library, see https://github.com/home-assistant/core/issues/114173#issuecomment-2073563347 If you're willing to help, it would be nice to have some real feedback.

mletenay commented 4 months ago

Proper support for Modbus/TCP was added in v0.9.9.18. When adding the integration, one can select either UDP (8899) or TCP (502). Enjoy.
