Re: Python Plugin: GoodWe solar inverter via SEMS API
So IK checked out the WiFi option. Turns out you need to have your firmware to a minimum level. Meaning, it can't be backward compatible so that would be a new plugin. Or an option in the current plugin (upside: you keep your historic data) but would complicate the plugin.
At this moment I'm focusing on another plugin so I'm not going to pursue the Wifi for now. Perhaps later.

Re: Python Plugin: GoodWe solar inverter via SEMS API
I get for months the following errors in domoticz:
What can I do about this?

Re: Python Plugin: GoodWe solar inverter via SEMS API
Hi,
This error occurs once in a while (I haven't seen it for quite some time though). It looks like the response from the webserver is not formatted correctly. It is nothing to worry about, the values correct themselves in the next update. And I cannot do anything about it as it is a problem on the server side......
Regards Jan-Jaap

Re: Python Plugin: GoodWe solar inverter via SEMS API
Since updating to Domoticz 2021.1 I have the strange issue that some of the device values do not reach InfluxDB, others still do.
Values that do reach InfluxDB: temperature, input 1 and 2 current power, inverter output power (usage)
Values that do not reach InfluxDB: inverter input 1 and 2 voltage, inverter output power (instant)
The domoticz log does say that the values are sent through influxLink.
I tried to delete the hardware and add it again. Also restored the database to before the update. No luck.
Does anyone know how to fix this?

Re: Python Plugin: GoodWe solar inverter via SEMS API
Hi,
This (normally) not any issue with the plugin, as the plugin writes data into the Domoticz database according to specifications. Apparently something changed between Domoticz and Influx, so I suggest to check the related topics of influx.

Re: Python Plugin: GoodWe solar inverter via SEMS API
Did you update to stable (build 13191) or to a beta 2021.1 (build > 13191)?
As there are things changing with regards to the Python Plugin framework in beta.

Re: Python Plugin: GoodWe solar inverter via SEMS API
I'm now on build 13360. But I think because of the issues, I tried the beta channel.
I've added the GoodWe hardware to my second Pi with Domoticz (stable 2021.1). Same result. The specific measures are not stored in InfluxDB.

Re: Python Plugin: GoodWe solar inverter via SEMS API
Can you try in your second Pi with stable to update one device with Domoticz http API call https://www.domoticz.com/wiki/Domoticz_API/JSON_URL%27s
If these updates are sent to influxDB then there is something wrong with the plugin or more likely with the Plugin Framework.

Re: Python Plugin: GoodWe solar inverter via SEMS API
Hi Vinjon,
I'm not seeing these errors here. Do they occur at every attempt to pol the Goodwe server (so every 5 minutes at the default update rate)?
Which server server do you connect to (I'm on 'Europe')?
If the problem persists, can you switch on debug log level and send me the complete logging so I can see what part of the return message is not working as expected?

Re: Python Plugin: GoodWe solar inverter via SEMS API
Error occurs only when I restart domoticz or disable/enable the hardware. Looks like no attempt to connect is made.JanJaap wrote: ↑Tuesday 17 August 2021 10:39 Hi Vinjon,

Loglevel is already on debug, this is all I get in the error log
I connect to Europe (but global gives the same result)

Re: Python Plugin: GoodWe solar inverter via SEMS API
OK, that provides some more info. And I can reproduce it. I'll try to fix this.
The plugin works such that it retrieves data on the stations from the web portal if not loaded locally. The API seems to have changed there...

Re: Python Plugin: GoodWe solar inverter via SEMS API
I have no errors until now, everything works fine. Although I do not understand what this local loading would mean.
My Sems server is Europe.

Re: Python Plugin: GoodWe solar inverter via SEMS API
It is an odd situation indeed since I haven't seen an update to the goodwe app on my phone, which would be expected when they change the API.
The local storage remark was incorrect that applies to another plugin I maintain. In this plugin I just go through all API calls at every update, which may be redundant. I'll see if I can improve that later.....

I have the same issues since 17-8. From the Domoticz errorlog:

Re: Python Plugin: GoodWe solar inverter via SEMS API
Yes, working on it. Seems that there is a couiple of things going on:
- I put some requests that are now not valid anymore
- I was querying for a list of stations but that endpoint seems not to work any more (was not used by others)
I'm close to a solution but need a bit more refactoring...

Re: Python Plugin: GoodWe solar inverter via SEMS API
OK, It's working for me now, hope this fixes it for all you guys out there. i will publish a newer, cleaned up version after my holiday, since it is now doing quite some steps redundantly but don't want to break it now that it finally works again

Re: Python Plugin: GoodWe solar inverter via SEMS API
ok, did not check in detail but in the newest version you have to supply the station id (as I can't query for that anymore) which I presume you did not do. So I fixed that now by making this an explicit error. Plus I fixed the issue with token being expired (which I forgot last night). Please give it another try.
