sensor unavailable

[EagleStClair]

Since a week or so my sensor.smhialert is just in state unavailable and the log only shows this error: 2023-01-16 08:47:39.441 ERROR (SyncWorker_6) [custom_components.smhialert.sensor] Unable to fetch data from SMHI. 2023-01-16 08:47:39.443 ERROR (SyncWorker_6) [custom_components.smhialert.sensor] 'approximateEnd' No changes done on my side other than updating home assistant. Might have been when updating to 2023.1 but I'm not sure.

I had this in the end of last year due to connection issues towards their servers.

Remote end closed connection without response

But after that it has worked fine and still does for me. However, I haven't upgraded hass for a while, maybe there is something with the latest versions.

I think this occurs when there is not 'approximateEnd' in the issued warning. I've seen it from time to time, and today I had the time to investigate a little closer. Here is one example:

{

    "normalProbability": true,

        }
    },

    "warningAreas": [

            "published": "2023-01-17T10:13:03.750Z",
            "normalProbability": true,
            "areaName": {
                "sv": "Hedströmmen",
                "en": "River Hedströmmen"
            },
            "warningLevel": {
                "sv": "Gul",
                "en": "Yellow",
                "code": "YELLOW"
            },
            "eventDescription": {
                "sv": "Höga flöden",
                "en": "High water discharge",
                "code": "HIGH_FLOW"
            },
            "affectedAreas": [
                {
                    "id": 19,
                    "sv": "Västmanlands län",
                    "en": "Västmanland County"
                }
            ],

We need to account for the possibility that the time frame of the issued warning is open..
