Custom FMI (Finnish Meteorological Institute) Weather & Sensor Platform

yr.no is included in the HA. This have been pretty shit from the start.

This is great integration, keep up the good work guys!

I’m not having actual problem / issue with integration, more like templating forecast data. I’d like to calculate heating degree day-number (lämmitystarveluku, FMI page on subject) for next day. Forecast data includes per hour temp forecast for next day and therefore, it should be possible to calculate. My idea is, that based on heating degree day forecast one could more accurately predict heating requirements and say, if electricity is cheap today, heat up energy storage in advance.

I remember HA Developer tools used to have long list of forecast attributes before, including temp, but it’s now remarkably shorter. However, this data is still available in weather card.

Any ideas how to calculate and template this data? It outputs just single number.

EDIT 21.07.2024:
Degree day calculation (lämmitystarveluku S17) template is now here

Hi Anand,
I installed the latest version of fmi 0.5.3 that was released in July 2024. I clreared the brower cache. Placed all files in custom component >fmi folder in HA directory. But in integration fmi is not showing even after restarting the HA. Could you please guide me on this.
I am using following versions
Core Home Assistant: 2024.10.1
Raspberry 5
Supervised Home Assistant: 2024.10.0
Using Duckdns domain

This integration stoopped working after core update 2024.10.2. Is there anything to do to get it working again?

Can’t get it to work anymore in 2024.10.2.

It seem to be working for me in apexcharts, but not in history view. Same thing with YR integration. So waiting for fixing in 2024.10.3

Seem to be something strange, because history view just started to work for both integrations.

2024.10.3 update did fix this.
