Open Meteo (open_meteo) integration date parsing issue.

[formatBCE]

The problem

Open Meteo integration reports incorrect day name in forecast. First of all, I checked server and client device time zone setting and it's correct, as well as Home zone coordinates. Time zome I live in is PST (America/Vancouver). On screenshot, there's time card with correct time/date and day name, and Open Meteo forecast information. Check the first day - it's showing day back from now, but temp/weather info for today.

On second screenshot you may see forecast info at the same moment.

Most probably, the problem is in parsing date string from datetime field (for other integrations it seems to be timestamp, but here it's string representation). I tried to use template to parse this date to day, and it works correctly.

I have the same display issue as @formatBCE . I am in time_zone America/Denver and on container version 2023.2.4, no errors in the logs. Appending T00:00:00 to the forecast datetime element using dev tools to manually override the value results in the day of week showing correctly, so it seems the date string by itself without time is indeed the problem:

I seem to be having the same issue. However, I am not using open_mateo. I have my own weather station that feeds to Weather Underground. I get a weather entity from that.

This morning, it switched to Sunny at 4AM, and then at 3PM, it switched to Clear-Night.

It's not stale, and still reproducible. I moved to different integration.
