Python plugin for Goodwe - local lan via udp

[kratax]

Hi,
Is there any alternative for home assistant goodwe plugin which directly reads data from local network (i.e. not via sems portal)?
Github page of home assistant version:
https://github.com/mletenay/home-assist ... e-inverter

Thanks a lot!
Regards,
Kratax

Good question!

I would love also to replace the web based currrent plugin with a (more reliable and no external dependent, SEMS portal is sometimes slow) with a local one.

Ok, good to know, I am currently considering if that's easier to adapt this to domoticz (not much experience with that so far) or to switch from domoticz to home assistant ...

Hey,

I'm maintaining the plugin for accessing the Goodwe inverter via the SEMS API. Reason for not (yet?) switching to the local lan option is the fact that you need to have the firmware upgraded for your inverter, which most people (my assumption) haven't done. Not sure how or since when new inverters are being delivered with new firmware.

I do see indeed errors and sometimes the data lagging, but overal it works ok. I've got some other plugins I? want to finish first, maybe I'll dive into this later. If you guys wanna dive in, I'll be happy to help.

You can submit a ticket at https://support.goodwe.com with the request for an firmware update so UDP readout becomes available. If you provide the serial number of your inverter they upgrade it over the internet within a week.

Can I help in the development of the plugin? No coding experience, but I can test?

[JanJaap]

I've got my hands full at this moment with 2 other projects + no real need for this (via web api works ok) so won't promise anything......

I created a plugin for Domoticz for local readout of a GoodWe inverter via modbus over UDP.
Works via LAN and WLAN. For XS inverter is firmware 1.xx.14 or higher required. Other GoodWe inverter model series (ET, EH, BT, BH, ES, EM, BP, DT, MS, NS) might work as well.

Currently the plugin is in working order but isn't (yet) in a shape to be released, so I'm looking for some beta testers to start in a couple of days. Please send me a message and I'll be contacting you back in a few days with some details to get you started.

Whenever you want to help beta testing I expect this from you:
1. You are familiar with Domoticz, know how to install and configure a plugin.
2. You are familiar with reading the Domoticz logs and are able to extract data from that to send to me.
3. You have a GoodWe inverter with the required firmware (For XS series firmware 1.xx.14 or higher) with a Wifi of LAN module which has been proven to already work with modbus over UDP on port 8899.
4. You have insight in your energy delivering stats (not in Domoticz, but in Sems, for example) so you can compare numbers between different systems.
5. You install and use the plugin at your own risk. If, for any reason, things break down, you lose data, Domoticz dies or anything else; its your own risk.

Edit: Hope this forum allows you to send me a PM or e-mail, so try that. Otherwise, maybe just reply below (without giving your e-mail address or other personal info in the post), then we will find another safe way to get the info.

Hi Remco, I'm interested.

Just received my goodwe 3600dns last month. Sems is very disappointing so looking for a way to log via local in domoticz.

My domoticz is on rPi bullseye so the other plugin isn't working.

Let me know what I can do.

[remcok]

Hi Remco, I'm interested.
...
Let me know what I can do.

Hi, I just finished publishing the beta version in my github account, you can find it here:
https://github.com/remco-k/domoticz-goo ... dp-plugin/

Please take a look at the readme, it will describe on how to install the plugin. If you find an issue, then please create an issue here, describe as much as possible on what the issue is and what you think is going wrong:
https://github.com/remco-k/domoticz-goo ... gin/issues

Hope it works for you, please let me know if this plugin works with your inverter.

[bvdf0251]

Hi, Took a little time(Bullseye and Python do not get along)

Updated Domoticz to beta and the plugin is now functional.

Did have to manually install pymodbus via 'pip install pymodbus' perhaps this should be added to 'requirements.txt'

Also notice that you have to have 'Accept new Hardware Devices' enabled or it will fail to create devices.

My Inverter is 3600T-DS with Wi-Fi module.

I do notice that today's and total generation don't match the device setting. In devices the total is 622, on the dashboard it started at 0 and is now being totalled.

Thanks, I added this to the requirements.

Also notice that you have to have 'Accept new Hardware Devices' enabled or it will fail to create devices.

I'm fairly new to Domoticz, about 3 to 4 weeks, this setting is in Setup->System, and I believe its normal that you need to enable it for devices to be added by plugins? And therefore device creation will fail if disabled. Or do you mean something else?

My Inverter is 3600T-DS with Wi-Fi module.

Noted as a reported working inverter.

I do notice that today's and total generation don't match the device setting. In devices the total is 622, on the dashboard it started at 0 and is now being totalled.

I believe this is normal as Domoticz didn't get the 'start of the day' value in the beginning of the day. Looking at other inverter plugins (I have a SolarEdge inverter as well), this looks the same.
I think if you have a look at it tommorow for that day, it should match up.

I pushed a new version with the above changes: beta-release-v0.0.2

[bvdf0251]

Yes I meant that setting. I've been using Domoticz for some 2 years now but never actually used a plugin till now.

It's no problem just something that I noticed.

As for the daily generation I understand that because of the timing I don't get everything today, however when you check the device in 'devices' it does show the correct daily generation. Meaning the data is there.

Same for the total generation.

https://drive.google.com/file/d/1Rblyhx ... p=drivesdk

Would be nice if we can get this data in the database so I have the total amount generated accurately.

HI there. I have the plugin running but it seems i can't get data from the inverter. Could it be that i'm running an older firmware? Where can i check the version of it?

On the other side it is showing 19 out of 34 values so data is coming trough in domoticz.

I also noticed when UDP is active, no SEMS portal data is coming trough. Is this because of the intercept of data?

Hey,

Reason for not (yet?) switching to the local lan option is the fact that you need to have the firmware upgraded for your inverter, which most people (my assumption) haven't done.

I have your plugin working, tnx! only downside is that it is only displaying one of the three phases of output (current and voltage) while it's a 3-phase inverter. Or can i tweak something in SEMS portal for this?

[JanJaap]

Hi Jeweettoch,

This topic is for the straight to the inverter via UDP plugin. For questions on the via-the-web version of goodwe SEMS plugin, please use this topic: Python Plugin: GoodWe solar inverter via SEMS API. I'm guessing it ain't all that hard to make, guessing data is there. In both of the plugins.

I have a GW5000D-NS, which is a single phase, dual input inverter, running software V1.1.2.1

This plugin in its current form does not work for my model. I have managed to get it working by making a few changes.

The biggest issue seems to be the detection of single vs 3 phase in the plugin. It tries to read vgrid2 and vgrid3, which fail (around line 315 in the code). By changing that part to force it always to single phase I got it to work.

For your reference, this is the output of my inverter from the first sample script:

And it generates these sensors:

There are a few that don't seem to be reporting the correct value. I will give a stab at it trying to figure out what to change to get it to work correctly.

Hi Remco,

How can I upgrade without losing history?

Thanks.

Hi, It that some body who will be to help me to make in LUA Fibaro HC3 make quick app for load data directly from local LAN for Goodwe via UDP protocol like is here or in HA.
