Fronius Inverter does not start

[na-ma-ste]

HI,

since today (Homebridge ui 4.57.1; node 20.11.0, homebirdge 1.8.4) I got this Error meessage on the console and the fronius plugin does not start and causes homebridge to stop work:

AxiosError: timeout of 2000ms exceeded at RedirectableRequest.handleRequestTimeout (/var/lib/homebridge/node_modules/homebridge-fronius-inverter-lights/node_modules/axios/lib/adapters/http.js:657:16) at RedirectableRequest.emit (node:events:518:28) at RedirectableRequest.emit (node:domain:488:12) at Timeout.

From the error it looks like there's a problem connecting to your inverter. In the past when I've run into similar problems it's either due to some WiFi connectivity issue (rebooting the router) or a bug with the inverter (reboot the inverter/datamanager).

I think you should also investigate changing the plugin to a child bridge so this error does not break your entire Homebridge instance. You can find the documentation for that here https://github.com/homebridge/homebridge/wiki/Child-Bridges

Hi @longzheng ,

thank you. i have now done a complete reboot of the PI and that has helped. The plugin is working again.

However, it always shows 100 (in the homebridge). Although other values are present.

Any Ideas?

[longzheng]

Which light is showing the 100? Import or export?

[na-ma-ste]

Import: 100 PV: 100 Export: 0 Load: 0

Values are continuous, i.e. no change for hours

Real Values: Import: 1 PV: 80 Export: 50 Load: 100

[longzheng]

@na-ma-ste That's very weird. Where abouts are you seeing the "real values"?

Does the data in http://YOUR_INVERTER_IP/solar_api/v1/GetPowerFlowRealtimeData.fcgi for P_Grid P_Load P_PV look reasonable?

If so, can you try restarting Homebridge again?

[na-ma-ste]

That works but i see some null values in the response:

{ "Body" : { "Data" : { "Inverters" : { "1" : { "DT" : 232, "E_Day" : 63930, "E_Total" : 24200800, "E_Year" : 10403875, "P" : 4403 } }, "Site" : { "E_Day" : 63930, "E_Total" : 24200800, "E_Year" : 10403875, "Meter_Location" : "unknown", "Mode" : "vague-meter", "P_Akku" : null, "P_Grid" : null, "P_Load" : null, "P_PV" : 4403, "rel_Autonomy" : null, "rel_SelfConsumption" : null }, "Version" : "12" } }, "Head" : { "RequestArguments" : {}, "Status" : { "Code" : 0, "Reason" : "", "UserMessage" : "" }, "Timestamp" : "2024-08-29T17:44:08+02:00" } }

[longzheng]

Hmm it looks like there's a fault with your smart meter connection, it's not sending the load value.

Can you try restart the Fronius inverter or data manager?

[na-ma-ste]

Hi @longzheng ,

everything is available and correct in the SOlar Web from Fronius and on my Varta storage system (where I read the values from above).

I also had the restart idea yesterday. I'll give it a try.

I've also noticed that I'm operating my Fronius in ‘night mode’. This means that it is off from sunset and does not provide any data. So far this has not been a problem, but after updating to UI 4.57.1 I get an Error (will try to send the error, made a copy of the log yesterday but forgot to save it :/ )

[longzheng]

everything is available and correct in the SOlar Web from Fronius and on my Varta storage system (where I read the values from above).

Right, I believe SolarWeb gets values pushed from the inverter by other means (not using this Solar API which this plugin uses) and the Varta storage system I presume would have meters/CT clamps separately to the Fronius system.

I'm guessing if you visited your Fronius datamanager IP directly and viewed the local UI it would also not show the load/grid values (since it uses the Solar API).

Hi @longzheng ,

i have done the restart, but the output looks same:

{ "Body" : { "Data" : { "Inverters" : { "1" : { "DT" : 232, "E_Day" : 18224, "E_Total" : 24416302, "E_Year" : 10619366, "P" : 2265 } }, "Site" : { "E_Day" : 18224, "E_Total" : 24416302, "E_Year" : 10619366, "Meter_Location" : "unknown", "Mode" : "vague-meter", "P_Akku" : null, "P_Grid" : null, "P_Load" : null, "P_PV" : 2265, "rel_Autonomy" : null, "rel_SelfConsumption" : null }, "Version" : "12" } }, "Head" : { "RequestArguments" : {}, "Status" : { "Code" : 0, "Reason" : "", "UserMessage" : "" }, "Timestamp" : "2024-09-02T13:00:26+02:00" } }

@na-ma-ste I'm not sure what's happening, I've not seen this before but it looks like there's something wrong with the meter data.

Unfortunately this is a bit of roadblock if the API isn't able to provide the correct site/load data then it won't be able to display the correct numbers.

[longzheng]

@na-ma-ste i saw someone write about this elsewhere.

Can you check the SolarWeb settings > components. Under Energy Meters look for column “Visible”. Make sure it is enabled.

[na-ma-ste]

Hi @longzheng ,

I check the Fronius Webinterface. I have only these two elements that fit to your request (the other are network, password and so on):

It looks that everything is active. Or do i need to check something else?

[longzheng]

I believe the other person was referring to the setting in Fronius Solarweb https://www.solarweb.com/

[na-ma-ste]

Ok, in Solor web it looks like this:

[longzheng]

@na-ma-ste Yeah it looks like there's something technically wrong with your meter, maybe a hardware fault? I would recommend contacting your solar installer to troubleshoot.
