Filtrando dados por período em gráficos no Node-RED (Dashboard 2.0) - Neo Responde EP.17

🤓 In this episode of Neo Answers, we show the solution to a very common question for those who use Node-RED with Dashboard 2.0: 👉 How to create charts connected to a database and allow filtering by start and end dates? In the video, we demonstrate in practice how to structure this type of solution, integrating database queries, data processing, and dynamic visualization on the dashboard, all in a low-code way and fully integrated with Node-RED. This type of approach is extremely useful for: 🔸 historical data analysis 🔸 operational dashboards 🔸 industrial metrics 🔸 visualization of IoT and automation data 🔸 absorption of expensive technology functions, such as supervisory systems and HMIs If you are migrating from Dashboard 1.0 to Dashboard 2.0, or want to create more professional and flexible interfaces in Node-RED, this video will help you a lot. 💬 If you also have a question or topic suggestion, leave it in the comments — your question could become a future Neo Answers!
