Hi,
I have a streaming dataset (e.g. real time temperature data) in Power BI via Stream Analytics. I have a category field called RoomName in that dataset (e.g. kitchen, bedroom) which allows me to see real-time temperature for each room. I want to see the latest temperature value for each room on a real-time basis in the following format:
| Room | Temperature | Time |
| Kitchen | 25 | 20/09/2017 17:12:30 |
| Bedroom | 23 | 20/09/2017 17:12:29 |
| Lounge | 24 | 20/09/2017 17:12:28 |
Could you please help how can I build the above data from the dataset? I have tried TOP 1 filtering based on the temperature value by latest time but that only gives me latest temperature value which in the above case is Kitchen temperature. I don't know how can I break that down by category. Any help will be appreciated. Thanks
