How do you connect to the inverter? Some of them (SUN2000 series I think) will only accept modbus connections when you are connected through the inverter WiFi access point.

gieljnssns commented 3 years ago

I'm connected through lan. (On the WiFi stick)

Emilv2 commented 3 years ago

You will need to set up a separate WiFi connection with the inverter WiFi access point to be able to connect with the modbus server.

gieljnssns commented 3 years ago

Now I have this error

Ok, seems like you are able to connect now, but reading the register fails. Do you happen to have anything else connected with the modbus server? It only supports one connection at the same time.

Do any other register addresses work? (Your device is listed as supported in the Interface.Definitions.V3.0.pdf so 30000 should work though)

Is that the app that uses cloud connection, or the one that needs a connection with the inverter WiFi access point? The cloud one shouldn't be an issue, but the other one might interfere.

gieljnssns commented 3 years ago

I think the cloud connection When I turn off wifi on my phone, the app still connects And I get this error on my Mac

Are you sure you are connected correctly? I see the subnet has not changed. You're still on 192.168.86.0/8. The inverter should have the address 192.168.200.1 (200 could be something else) when you connect to it's AP.

gieljnssns commented 3 years ago

I'm sorry, I've found it... Now my nuc is connected to my main Lan through ethernet (like it always was) AND my nuc is connected through wifi to the inverters AP. And now I use

This will be fixed once we can use async pymodbus, for now the component is just slow.

For the other issues, does it happen very often? I would just ignore it if it doesn't happen too often, I don't think I can do anything about it anyway...

It happens +/- 2 times an hour...

Exactly, I have the same problem. The biggest problem is that going back to the previous verse doesn't help. Any idea?

Ok, give me some time. I just found out it's possible to install requirements from git, so I think I will just make it async first and see if that solves the issue.

JacoboSanchez commented 3 years ago

Don't know if it was casual or not, but after some tests downloading (not using as they do not work with huawey) other modbus integration (SAJ Inverter Modbus) this integration started working again. Probably unrelated but if anyone wants to try... i have two sun2000 currently working in HA

javierin commented 3 years ago

I currently monitor the inverter using another app via modbus-tcp. However If I try to connect HA also to the same modbus IP/port, everything collapses and it stops responding. Is this a firmware version related issue on the side of the inverter or a limitation in modbus-tcp specifications (no more than a single client expected).

Thanks!

Emilv2 commented 3 years ago

@javierin As far as I know this is a limitation in the modbus-tcp implementation on the inverter, only one client at a time can connect.

Apparently there is a firmware update for a dongle that solves some issues with modbus: https://community.openhab.org/t/reading-data-from-huawei-inverter-sun-2000-3ktl-10ktl-via-modbus-tcp-and-rtu/87670/83?u=emilv2, but I don't know anything about firmware updates for the inverter. You could always try to contact Huawei to see if there are firmware updates for your inverter at: eu_inverter_support@huawei.com.

javierin commented 3 years ago

Yes, I recently upgraded the dongle to a newer version, but that was a couple of months ago, I have sent support an email asking for any updates.

Thanks

Matthias54321 commented 2 years ago

Hi,

this application is exactly what I was looking for.

Unfortunately I can't get it to run.

I have a Sun2000 6 KTL M1 whose IP in the network I know.

I installed the repository via HACS as a custom repository and it is now also available as an integration under HACS.

Additionally I added the part for the sensor in configuration.yaml.

sensor:

But now I can't find any sensor or anything from the inverter, did I forget something?
