Incorrect Maximum Temperature Readings for Next 17 Hours #57

Closed kineci closed 1 month ago

kineci commented 1 month ago

I've used the node-red-contrib-dwd-local-weather node to receive the maximum temperature forecast for the next 17 hours. However, the resulting output is significantly lower than expected. According to the node's output, the maximum temperature is far lower than what is currently observed and forecasted by the same MOSMIX station online.

Current Behavior: The node output indicates a maximum temperature of around 23.7°C for the next 17 hours. Actual temperatures observed and forecasted online for the same MOSMIX station (P0037) show around 25.2°C.

Expected Behavior: The maximum temperature forecast provided by the node should match the temperatures observed and forecasted online for the same stations.

Steps to Reproduce: Configure the node-red-contrib-dwd-local-weather node with MOSMIX Station P0037. Set the "Look ahead hours" to 17. Add ">°TX" to the additional fields to get the maximum temperature. Trigger the node and observe the output.

Node-RED version: 4.0.0 node-red-contrib-dwd-local-weather version: 1.0.5

Additional Context: I have tested with nearby stations, and the results are similarly lower than expected. The temperature values observed online are consistent with other weather services, indicating that the node's output may be incorrect. The acutal temperature today is 27°C according to dwd online with an actual warning about immense heat. So even the mosmix station readings online ar lower than expected, but getting 23.7°C from the node is even more off and does not represent the real conditions at all.
