Error message to Domoticz

[Henry]

I've created a small Node-Red flow that reads the information from my Kia EV6 using Bluelinky every 10 minutes.
Most of the time this goes ok, but sometimes there is an error in the communication. Now i'm looking for a way to send part of this message to Domoticz.
The error looks like this:

Code: Select all

ManagedBluelinkyError: @EuropeVehicle.fullStatus: [401] Unauthorized on [GET] https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fprd.eu-ccapi.kia.com%3A8080%2Fapi%2Fv2%2Fspa%2Fvehicles%2Fd717d170-e9b2-4000-9144-4cc82bff4ad1/location - {"error":"Key not authorized: Token is expired"}

And I want the part between braces sent to a Domoticz device.
Because it's not a json message I'm note sure how I can handle this.

Hello Henry,

You wrote:

The error message tells you that the "Key not authorized: Token is expired" .

I would recommend to renew the token, however I do not know what BlueLinky requires.
Sending it to Domoticz doesn't look very useful, unless you want a notification.
I would say, use the message as a trigger to renew the token.

And I want the part between braces sent to a Domoticz device.

I think you mean the part between the curly brackets:

Code: Select all

{"error":"Key not authorized: Token is expired"}

This is JSON and the only thing we have to do is to extract that JSON part from the string.

Currently it is not possible to add a screenshot.

See flow below:

You have to add a contrib node with the Palette Manager (node-red-contrib-string)

Hi Firewizard,

The error message tells you that the "Key not authorized: Token is expired" .

I would recommend to renew the token, however I do not know what BlueLinky requires.
Sending it to Domoticz doesn't look very useful, unless you want a notification.
I would say, use the message as a trigger to renew the token.

For now it's just a notification to see how often this happens. There is a limit of 200 calls per day to the api and I don't want to create an endless loop caused by a trigger.
It's working so I will see if it's a problem that is resolved by a next call.

Thanks
